Please help.Find the circumference (to the nearest whole number). Use 3.14 for pi.

A.116 in
B. 88 in
C.44in
D.None of the above

Answer/Step-by-step explanation:

Recall the acronym, SOHCAHTOA.

✔️Cos X = adj/hyp (CAH)

Adj = 10

Hyp = 26

Cos X = 10/26

Simplify

Cos X = 5/13 (as a fraction)

Cos X = 0.3846 (as a decimal to 4 d.p)

✔️Cos Z = adj/hyp (CAH)

Adj = 24

Hyp = 26

Cos Z = 24/26

Cos Z = 12/13 (as a fraction)

Cos Z = 0.9231 (as a decimal to 4 d.p)

Answer:

Alr what do you need help with

Answer:

$0.90

Step-by-step explanation:

So first you need to find the rate (showing how much money it costs to run for 1 hour) so you get 0.60 and divide it by 4 and its 0.15, then multiply 0.15 by 6 and get 0.90

the answer to your question might be (B).

Answer:

-18x^2+17x-9

Step-by-step explanation:

Answer:

9 days

Step-by-step explanation:

1= 9*(1.04)^d

12.81/9= (1.04)^d

1.423= (1.04)^d

log(1.423)= d *log(1.04)

0.1532=d * 0.017

d= 0.1532/0.017

d=9

The reasonable domain to plot the growth function is in the interval [0,9].

Answer:

Step-by-step explanation:

Equation of circle: (x - h)² + (y -k)² = r²

(x+ 3)² + (y + 9)² = 144

(x+ 3)² + (y + 9)² = 12²

h = -3 ; k = -9

Answer:

The game ends at 2:39

Step-by-step explanation:

11:50 + 3 hours (3:00) = 2:00

2:00+ 0:39 = 2:39

Answer:

Step-by-step explanation:

The null and the alternative can be computed as:

[tex]H_o : \mu = 7.62[/tex]

[tex]H_1 : \mu < 7.62[/tex]

[tex]Claim: \mu < 7.62[/tex]

[tex]\alpha= 0.05[/tex]

The critical value for a left-tailed test at [tex]\alpha= 0.05[/tex] = -1.645

The test statistics can be computed as:

[tex]Z = \dfrac{\overline x - \mu}{\dfrac{\sigma}{\sqrt{n}} }[/tex]

[tex]Z = \dfrac{6.78 - 7.62}{\dfrac{1.77}{\sqrt{54}} }[/tex]

[tex]Z = -3.487[/tex]

The P-value = (Z< -3.487)

The P-value = 0.00024

Decision Rule: TO reject [tex]\mathbf{H_o}[/tex] at [tex]\alpha= 0.05[/tex], if test statistics is less than the critical value (left tailed)

Conclusion: We reject  [tex]\mathbf{H_o}[/tex] at ∝ = 5%, thus there is enough evidence to support the claim that the college students average daily ownership expenses are less than the national average.

Answer:

x=0.5

Step-by-step explanation:

Simplifying

4x + -3(2x + -1) + -4x = 0

Reorder the terms:

4x + -3(-1 + 2x) + -4x = 0

4x + (-1 * -3 + 2x * -3) + -4x = 0

4x + (3 + -6x) + -4x = 0

Reorder the terms:

3 + 4x + -6x + -4x = 0

Combine like terms: 4x + -6x = -2x

3 + -2x + -4x = 0

Combine like terms: -2x + -4x = -6x

3 + -6x = 0

Solving

3 + -6x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + -6x = 0 + -3

Combine like terms: 3 + -3 = 0

0 + -6x = 0 + -3

-6x = 0 + -3

Combine like terms: 0 + -3 = -3

-6x = -3

Divide each side by '-6'.

x = 0.5

Simplifying

x = 0.5

This question is incomplete, the complete question is;

Set up an integral for the volume of the solid obtained by rotating the region bounded by the given curves about the specified line. Then use your calculator to evaluate the integral correct to five decimal places.

x² + 9y² = 9

(a) About

y = 3

(b) About  

x = 3

Answer:

a) the volume of solid revolution is 18π² = 177.652879 ≈ 177.65288

b) the volume of solid revolution is 18π² = 177.652879 ≈ 177.65288

Step-by-step explanation:

a) the volume of solid of revolution

about y=3

Using SHELL METHOD;

Volume V = 2π . [tex]\int\limits^1_{y=-1} \,[/tex] (3-y) (2.3√(1-y²)) dy

= 12π . [tex]\int\limits^1_{y=-1} \,[/tex]  (3-y) √(1-y²) dy

= 12π . [tex]\int\limits^1_{y=-1} \,[/tex]  (( 3√(1-y²) - y(√(1-y²)) dy

= 12π[ [tex]\frac{3}{2}[/tex]π - 0 ]

= 18π² = 177.652879 ≈ 177.65288

Therefore, the volume of solid revolution is 18π² = 177.652879 ≈ 177.65288

b)

the volume of solid of revolution

about x=3

Using SHELL METHOD;

Volume V = [tex]\frac{4}{3}[/tex]π . [tex]\int\limits^3_{y=-3} \,[/tex] (3-x) ([tex]2.\frac{1}{3}[/tex]√(9-x²)) dx

= [tex]\frac{4}{3}[/tex]π . [tex]\int\limits^3_{y=-3} \,[/tex] (3-x) √(9-x²) dx

= [tex]\frac{4}{3}[/tex]π . [tex]\int\limits^3_{y=-3} \,[/tex] (3√9-x² -x√(9-x²) dx

=  [tex]\frac{4}{3}[/tex]π [ [tex]\frac{27}{2} \pi[/tex] - 0 ]

= 18π² = 177.652879 ≈ 177.65288

Therefore, the volume of solid revolution is 18π² = 177.652879 ≈ 177.65288

They would need to sell 32 calendars to EXCEED their goal.

Explanation:

8 x 32= 256, which is more than the $250 needed!

Step-by-step explanation:

Answer:

a=7

Step-by-step explanation:

7(sq rt 2)=(sq rt 98)

sin 45=a/(sq rt 98)

0.7071=a/(sq rt 98)

a=0.7071(sq rt 98)

a=7

Answer:

36+16= 52

4(9)+4= 40, which does not equal 52.

4(9+4) = 52.

6(6+8) = 84, which does not equal 52.

(6+4)(6+4) = 100, which does not equal 52.

So, 4(9+4) is correct.

Let me know if this helps!

For 0<x<4, the average rate of change will be -60

For 4<x<8 the the average rate of change will be -31

And for the sentence (on savass in order is)

Stay negative, -31, decrease but at a slower rate

In this exercise we have to use the knowledge of functions to describe the average rates of each one of them, so:

For 0<x<4 will be -60

For 4<x<8 will be -31

First, we have to remember what an average rate means, like:

So we can say that:

[tex]0
