Answer:

Well it is 16

Step-by-step explanation:

the rectangle has 2 of the same sides for each side, so 3x2+5x2, a square has all sides equal to each other, so 4x4

So Now we do the easy part|
The rectangle that is grey:
3x2 = 6
5x2 = 10
6+10 =16

The orange square:
4x4 = 16
4+4=8
4+4=8
8+8=16

Therefore both are 16, meaning 16 must be the perimeter for both!

Answer:

cos(x)=10/15

Step-by-step explanation:

As cosine is Base/Hypotenues

cos(x)=JL/JK

= 10/15

The equation used to find the measure of angle LJK is option C. cos(x) = 10/15.

Trigonometric functions are the functions which are represented as the ratio of the sides of a right angled triangle.

The three main trigonometric functions are sine, cosine and tangent function.

Sine function of an angle is the ratio of the opposite side to the hypotenuse of the triangle.

Cosine function of an angle is the ratio of the adjacent side to the hypotenuse of the triangle.

Here,

Hypotenuse of the triangle = KJ = 15 inches

LJ = 10 inches is the adjacent side with respect to the angle x.

We can use cosine function here.

cos (x) = LJ / KJ = 10/15

Hence the equation used is cos(x) = 10/15.

the lengths in inches of the legs XY and XZ are, 5.53 & 7.36 .

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.

here, we have,

in right triangle ,XYZ, the length of the hypotenuse YZ=85 and tanZ=3/4.

so, we get,

let, the sides= 3x & 4x

now, by Pythagorean theorem,

9x^2 + 16x^2 = 85

x=1.84

hence,  the lengths in inches of the legs XY and XZ are, 5.53 & 7.36 .

Step-by-step explanation:

m = k/m     sub in the values given

-4 = k / 17

k = -68

so    m = -68/n     NOTE: this can also be written as  n = -68/m

Answer:

Step-by-step explanation:

Nikki,  they wrote the problem in a format that is general

y = k/ x      for the given variables  m and n  then

m = k / n   where k is some constant ( konstant)

plug in the given numbers for m and n

-4 =k / 17

solve for k

-4 * 17 = k

-68 = k

now we have a better formula

m = -68 / n  ( this is your answer a )

now plug in -136 for m

-136 = -68 / n  

solve for n

n = -68 / -136

n = 1/2   ( this is your answer b)

Answer:

y = 108°

Step-by-step explanation:

3x - 12 and 2x + 16 are corresponding angles and are congruent , then

3x - 12 = 2x + 16 ( subtract 2x from both sides )

x - 12 = 16 ( add 12 to both sides )

x = 28

then

3x - 12 = 3(28) - 12 = 84 - 12 = 72°

y and 3x - 12 are adjacent angles and sum to 180° , that is

y + 72° = 180° ( subtract 72° from both sides )

y = 108°

Answer: 70

Step-by-step explanation: BAD is 110 degrees and BDE is 180 so do 180 minus 110 and gets you 70 which is DE

Reason:

Central angle BAD is 110 degrees.

This makes angle DAE to be 180-110 = 70 degrees since the two angles are supplementary. They combine to a 180 degree straight angle.

From there, minor arc DE is also 70 degrees. This is because the central angle subtending the arc will be the same measure.

Answer: f(x) = 90,200 (1-.002)^7

Step-by-step explanation:

f(x) = a (1 - r)^t

f(x) = 90,200 (1-.02)^7

The equation f(7) = 90,200 (1 - 0.02)⁷  represents the town’s population after 7 years.

An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.

A town has a population of 90,200 and shrinks at a rate of 2% every year.

As we know the exponential equation for the population as

f(n) = a (1 - r)ⁿ

Where a is the initial population

r is rate

n is years

As per the question, we have

a = 90,200, r = 2/100 = 0.02, and t = 7 years

Substitute the known values in the above equation, and we get

f(7) = 90,200 (1 - 0.02)⁷

This equation represents the town’s population after 7 years.

Using quadratic function concepts, it is found that:

a) The equation is: 16t² - 64 = 0.

b) It takes 4 seconds before the weight is caught by the net.

It is given by:

h(t) = -16t^2 + v(0)t + h(0).

In which:

Item a:

In this problem, the object starts from rest at a height of 67 ft, hence v(0) = 0 and h(0) = 67.

Then, the equation for the height is given by:

h(t) = -16t^2 + v(0)t + h(0)

h(t) = -16t^2 + 67

It hits the net when h(t) = 3, hence:

3 = -16t^2 + 67

16t² - 64 = 0.

Item b:

16t² = 64

[tex]t = \pm \sqrt{4}[/tex]

t = 4, as time is positive.

It takes 4 seconds before the weight is caught by the net.

The percentage that the cost of 1 kg apple is more than 1 kg of orange is 100%.

5o + 3a = 1100 equation 1

2.4o + 3.15a = 870 equation 2

Where:

Multiply equation 1 by 1.05

5.25o + 3.05a = 1155 equation 3

Subtract equation 3 from equation 2

285 = 2.85a

a = $100

Substitute for o in equation 1

5(100) + 3a = 1100

500 + 3a = 1100

3a = 600

we know thatthe equation of the circle is of the formwhere(h,k) is the center of the circler is the radius of the circlein this problem we havesothe center is the point the radius is thereforethe answer isThe radius of the circle is equal to  4units

The required radius of a circle whose equation is (x + 5)² + (y - 3)² = 4² is 4. Option B is correct.

The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by

(x - h)² + (y - k)² = r²

where h, k is the coordinate of the center of the circle on a coordinate plane and r is the radius of the circle.

The equation of the circle is given by:

(x + 5)² + (y - 3)² = 4²

Comparing this equation with the standard form of the equation of a circle:

(x - a)² + (y - b)² = r²

We can see that the center of the circle is at the point (-5, 3), and the radius of the circle is 4 units (which is the same as the constant on the right-hand side of the equation).

Therefore, the radius of the circle is 4 units.

So the answer is (B) 4 units.
