Please help me solve this question

Note :

sin(x) = cos (90-x)

Therefore,

sin(x-3) = cos(90-(x-3))

90-[x-3] = 2x+6

90-x+3 = 2x+6

3x = 93-6

x = 31-2

x = 29°

Answer:

Step-by-step explanation:

If you multiply top and bottom of 7/2 by 2 as in (7 *2) / (2 * 2) = 14 /4

If you multiply 7/2 top and bottom by 4, you get 28/8

So 14/4 and 28/8 are both the same as 7/2

To calculate a point estimate, we need to know the sample size.

Explanation:

Let's go through the answer choices.

ok so they raised 12%

12%=12/100=0.12

12% of 552.5=.12 times 552.5=66.3 was raised

552.5-66.3=486.2

divide by 7

486.2/7=69.457 about 69.46

each member must raise at least 69.46

The percent of his monthly budget that his transport costs account for will be 17.8%.

The percent of his monthly budget that his transport costs account for will be:

= 325/(800 + 450 + 125 + 325 + 125) × 100

= 325/1825 × 100

= 17.8%

The percent of his monthly budget has he accounted for will be:

= 1825/2500 × 100

= 73%

When he saves 10% of his take-home pay towards retirement, the amount saved will be:

= 10% × $2500

= $250

The percent of Rayan's monthly budget that his transport costs account for will be 17.8%.

1. The proportion of his monthly budget that his transit expenses make up is:

= 325/(800 + 450 + 125 + 325 + 125) × 100

= 325/1825 × 100

= 17.8%

The proportion of his monthly budget that he has already accounted for is:

= 1825/2500 × 100

= 73%

He will save the following sum for retirement if he sets aside 10% of his after-tax income:

= 10% × $2500

= $250

The answer is $250.

2. To find the percentage of his monthly budget accounted for by transport costs, we add up the amounts for Car Payment and Gas:

$325 + $125 = $450.

Then we calculate the percentage: (450 / 2500) x 100% = 18%. Therefore, his transport costs account for 18% of his monthly budget.

3. To find the percentage of his monthly budget accounted for overall, we sum up all the amounts in the table:

$800 + $450 + $125 + $325 + $125 = $1,825.

Then we calculate the percentage: (1825 / 2500) x 100% = 73%. Therefore, he has accounted for 73% of his monthly budget.

4. To calculate how much Ryan can save each month for retirement, we take 10% of his take-home pay:

10% of $2,500 = $250.

Thus, he can save $250 each month for retirement.

Answer:

10 sqrt 3

Step-by-step explanation:

sqrt (30) * sqrt (10) = sqrt (300) = sqrt ( 4 * 25 * 3) = 10 sqrt 3

Step-by-step explanation:

The equation of a circle is

[tex](x - h) {}^{2} + (y - k) {}^{2} = {r}^{2} [/tex]

Where (h,k) is the center and

r is the radius.

Here the center is (-9,10).

To find the radius, find the distance from the center to a point on the circle.

So find the distance between (-9,10) and (-9,7).

[tex]r = \sqrt{(( - 9 - ( - 9) {}^{2} + (10 - 7) {}^{2} } [/tex]

[tex]r = \sqrt{0 + 9} [/tex]

[tex]r = \sqrt{9} [/tex]

[tex]r = 3[/tex]

So the radius is 3 so we plug in

[tex](x - ( - 9) {}^{2} + (y - 10) {}^{2} = {3}^{2} [/tex]

[tex](x + 9) {}^{2} + (y - 10) {}^{2} = 9[/tex]

Answer:

○ [tex]\displaystyle (x + 9)^2 + (y - 10)^2 = 9[/tex]

Explanation:

Accourding to one of the circle equations, [tex]\displaystyle (x - h)^2 + (y - k)^2 = r^2,[/tex]the centre of the circle is represented by [tex]\displaystyle (h, k).[/tex]Moreover, all negative symbols give you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must pay cloce attention to which term gets which symbol. Another thing you need to know is that the radius will ALWAYS be squared, so no matter how your equation comes about, make sure that the radius is squared.

Answer: [tex]f(x)=2x^2+5[/tex]

Step-by-step explanation:

First integrate f'(x) so we can find the funtion f(x):

[tex]4\int\limits {x} \, dx =4[\frac{1}{2} x^2]=2x^2+C=f(x)[/tex]

The initial conditions say that when x = 0, the function equals 5. Let's write that down:

[tex]f(0)=5=2(0^2)+C=C[/tex]

Therefore, the integration constant 'C' must equal 5. This means that our function is:

[tex]f(x)=2x^2+5[/tex]

The volume of the cylinder container is the amount of milk in it

The most accurate measurement for the radius is 3 inches

The given parameters are:

The volume of a cylinder is:

V = πr²h

So, we have:

πr² * 8 = 231

Divide both sides by 8π

r² = 9.19

Take the square root of both sides

r = 3.03

Approximate

r = 3

Hence, the most accurate measurement for the radius is 3 inches

Answer:

-35, 2

Step-by-step explanation:

When you multiply -35*2 you will get -70

When you add a positive number to a negative number you will take the larger number and if it is negative you will add the positive and if it is positive you take away negative so -35+2 will be -33

General form of a quadratic equation: [tex]ax^2+bx+c[/tex]

To calculate the x-coordinate of the vertex

  ⇒use x = [tex]-\frac{b}{2a}[/tex]   <--- this is a property that helps you find the vertex of the

Since x = -1:

    ⇒ we can plug in this x-value into the original equation to find the y-

Answer:

1, 9 and 10.

Step-by-step explanation:

Let the 3 numbers be x, y  and z, then

x + y + z = 20

xyz = 90

Assuming the numbers are whole numbers lets find the prime factors of 90:

90 = 2*3*3*5

So we need to combine these factors to fit the 2 eqautions.

Now 90 = 9 * 10

= 1 * 9 * 10

If we include 1 as one of the 3 numbers then 1, 9 and 10 will fit the bill.

Answer:

f(h + 2) = 2h² +8h - 19

Step-by-step explanation:

f(x) = 2x² - 27

f(h + 2) = 2(h + 2)² - 27

f(h + 2) = 2(h²+4h+4) - 27

f(h + 2) = 2h² + 8h + 8 - 27

f(h + 2) = 2h² +8h - 19
