Answer:

Step-by-step explanation:So that is a right angle,which means the sum is 90 degrees.so you subtract 90 from 62 then you have your answer.

Answer:

x = 28°

Step-by-step explanation:

It is given that the full angle measurement is a right angle (90°), denoted by the blue(?) box.

Set the equation:

Total angle measurement (90) = x + 62

I~

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 62 from both sides of the equation:

90 (-62) = x + 62 (-62)

x = 90 - 62

x = 28

if you invest $2,500 at a weekly compounding rate of 4.5% for 4 years, you will have approximately $3,157.22 to use as a down payment on your Can-Am Spyder.

How to solve investment?

If you invest $2,500 at a 4.5% weekly compounding rate, it will grow to a considerable amount in 4 years. To calculate this, we need to use the compound interest formula:

A = P(1 + r/n)

Where:

A = the final amount

P = the principal amount (initial investment)

r = the annual interest rate

n = the number of times the interest is compounded per year

t = the number of years

In this case, we have:

P = $2,500

r = 4.5% = 0.045

n = 52 (since compounding is weekly)

t = 4 years

Plugging in these values, we get:

A = $2,500(1 + 0.045/52) in power (52*4) = $3,157.22

So, if you invest $2,500 at a weekly compounding rate of 4.5% for 4 years, you will have approximately $3,157.22 to use as a down payment on your Can-Am Spyder.

It's important to note that this calculation assumes that the investment vehicle will have a steady and reliable return rate for the entire 4 years. There is always some level of risk involved with investing, so it's important to do your research and make informed decisions about where to put your money.

The better buy for david is churro at the swap

To determine which is the better buy for David, we need to compare the cost per churro for each purchase.

For the farmers market purchase, David bought 3 churros for $2.1, so the cost per churro is:

Cost per churro at farmers market = 2.1/3 = 0.7

For the swap meet purchase, David bought 5 churros for $3.20, so the cost per churro is:

Cost per churro at swap meet = 3.2/5 = 0.64

Answer:

Your friend's error is that having two equal discriminants doesn't necessarily mean that the two quadratic equations will have the same roots. The discriminant of a quadratic equation determines whether the roots are real, complex, or equal. If two quadratic equations have the same discriminant, then they have the same nature of roots, but that does not mean that their roots are equal.

As an example, consider the following two quadratic equations:

1. x^2 + 4x + 4 = 0

2. x^2 + 6x + 9 = 0

Both equations have the same discriminant: (b^2 - 4ac) = 16 - 16 = 0, but their roots are different. The first equation has one real root: x = -2, while the second equation has only one root, which is repeated twice: x = -3.

Therefore, it is incorrect to conclude that two quadratic equations have the same roots just because they have the same discriminants.

In mathematics, a coordinate is a number or combination of integers that indicates the location of a point or object in space. Coordinates are frequently used to define a point or object's position in a specific coordinate system, such as the Rectilinear or polar coordinate systems. In the Cartesian coordinate system, a point is located by its distance from the origin along the x-axis and its distance first from origin along the y-axis. These distances are represented by two digits, the x-coordinate and indeed the y-coordinate. The point's position in the plane is specified by the two coordinates.

(x', y') = (x, y) - (a, b)

a) To find the coordinates of K', we need to use the above formula with (a, b) = (-6, 2) and (x, y) = (3, 4) (the coordinates of K in the original figure)

(x', y') = (x, y) - (a, b)

= (3, 4) - (-6, 2)

= (3 + 6, 4 - 2)

Therefore, the coordinates of K' are (9, 2).

(x', y') = (x, y) - (a, b)

Answer:

The circumference of a circle is calculated using the formula `C = 2πr`, where `r` is the radius of the circle. Since you have given the radius as 4 and asked to use 3.14 for π, we can calculate the circumference as `C = 2 x 3.14 x 4 = 25.12`.

The area of a circle is calculated using the formula `A = πr^2`, where `r` is the radius of the circle. Using the same values for π and r as before, we can calculate the area as `A = 3.14 x (4)^2 = 50.24`.

So, for a circle with a diameter of 8 and a radius of 4 (using 3.14 for π), its circumference is approximately **25.12** and its area is approximately **50.24**.

Step-by-step explanation:

A dilation is a transformation that enlarges or reduces an object by a certain scale factor, and it is centered at a fixed point. In this case, we want to dilate the point (-3, 0) by a scale factor of 2, and the center of dilation is at the origin (0, 0).

To perform the dilation, we first need to find the distance between the point (-3, 0) and the center of dilation (0, 0), which is simply the magnitude of the vector (-3, 0), or 3.

Next, we need to multiply this distance by the scale factor of 2 to get the new distance after dilation, which is 6.

Finally, we need to find the point that is 6 units away from the origin along the same line that passes through the origin and the original point (-3, 0). This can be done by multiplying the direction vector of this line by the distance of 6 and adding the result to the center of dilation (0, 0). The direction vector is (-3, 0), normalized to have unit length, which is (-1, 0).

So the image of (-3, 0) after dilation by a scale factor of 2 centered at the origin is:

(-1 * 6, 0 * 6) + (0, 0) = (-6, 0)

Therefore, the image point is (-6, 0).

The vertex of a parabola in the form of y = a[tex]x^{2}[/tex] + bx + c can be found using the formula x = -b/2a for the x-coordinate of the vertex and then substituting this value into the equation to find the y-coordinate.

For the function g(x) = 3[tex]x^{2}[/tex] - 12x + 7, we can see that a = 3 and b = -12. We can use the formula to find the x-coordinate of the vertex:

x = -b/2a = -(-12)/(2*3) = 2

So the x-coordinate of the vertex is 2. To find the y-coordinate, we can substitute x = 2 into the equation:

g(2) = 3 [tex](2)^{2}[/tex]- 12(2) + 7 = -5

Therefore, the vertex of the function g(x) = 3[tex]x^{2}[/tex] - 12x + 7 is at (2, -5).

Answer:

Step-by-step explanation:

if it helped you please mark me a brainliest :))

Answer/Step-By-Step Explanation:

Part A:

To determine the measure of angle A (m/A), we can use the Law of Cosines, which states that:

c^2 = a^2 + b^2 - 2ab*cos(A)

where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Substituting the given values, we have:

(32)^2 = (16)^2 + (16√5)^2 - 2(16)(16√5)*cos(A)

Simplifying:

1024 = 256 + 1280 - 512√5*cos(A)

512√5*cos(A) = 512

cos(A) = 1/√5

Using a calculator, we find:

A ≈ 63.43 degrees

Therefore, m/A ≈ 63.43 degrees.

Part B:

To use the unit circle to find tan A, we first draw a unit circle with its center at the origin of a coordinate plane. We then draw a ray from the origin through the point (1,0) on the circle, which corresponds to the angle of 0 degrees.

Next, we draw another ray from the origin through the point on the circle that corresponds to angle A. This ray intersects the circle at a point (x,y), where x = cos(A) and y = sin(A).

Since cos(A) = 1/√5, we have:

x = cos(A) = 1/√5

To find y, we use the Pythagorean theorem:

x^2 + y^2 = 1

Substituting x = 1/√5, we get:

(1/√5)^2 + y^2 = 1

y^2 = 4/5

y = ± 2/√5

Since angle A is in the first quadrant, we take y = 2/√5.

Therefore, tan(A) = y/x = (2/√5)/(1/√5) = 2.

Part C:

To calculate the area of triangle AABC, we can use Heron's formula, which states that:

Area = √(s(s-a)(s-b)(s-c))

where s is the semiperimeter of the triangle, given by:

s = (a+b+c)/2

Substituting the given values, we have:

s = (16+16√5+32)/2 = 24+8√5

Using this value of s, we can calculate the area:

Area = √[(24+8√5)(8√5-8)(8√5)(24-8√5)]

Simplifying:

Area = √[4096] = 64

Therefore, the area of triangle AABC is 64 square inches.

In this problem, we use the tangent function to solve for angle A, understand that the unit circle cannot be directly used to find the tangent of A, and finally find the area of the triangle using the formula 1/2*base*height.

Part A: Assuming triangle AABC is a right triangle, we can determine m∠A by using the tangent function (tan ∠A = opposite side / adjacent side). Here, the opposite side is 'b' and the adjacent side is 'a'. So, m∠A = tan⁻¹ (b/a) = tan⁻¹ (16 5/16). To get the correct result, we then use a calculator with the inverse tangent or arctan function.

Part B: The unit circle is a fundamental tool in trigonometry. But in this case, having calculated m∠A in Part A, we cannot directly use the unit circle to find tan A as tan A is not represented on the unit circle.

Part C: The area of a triangle can be calculated using the formula 1/2*base*height. In a right triangle, this can be represented as 1/2*a*b: 1/2*16*16 5 = 130 square inches.

Step-by-step explanation:

The Jumble is an MP3 player owned by Greg. The Jumble chooses music for the user to hear at random. Greg's Jumble features nine rap tracks, seven rock songs, and six classical songs.  The probability of not selecting a rap song is 0.59.

The total number of songs on the Jumble is 6 + 7 + 9 = 22.

To find the probability of not selecting a rap song, we need to find the number of songs that are not rap songs, which is the sum of the number of classical and rock songs on the Jumble:

6 + 7 = 13

Therefore, the probability of not selecting a rap song is:

13/22
