Answer:

v=14.1cm^{3}

Step-by-step explanation:

1. Write the equation of the volume of sphere.

v=\frac{4}{3} \pi r^{3}

2. Substituting the given values.

v=\frac{4}{3} \pi (1.5)^{3}

v=14.137cm^{3}

3. Round the answer to the nearest tenth of a centimeter.

v=14.1cm^{3}

Find the unknown side length x write your answer in simplest radical form
Sauron [17]

Answer:

(B)4\sqrt{37}

Step-by-step explanation:

First, we determine the height of the triangle which we label as y.

Using Pythagoras Theorem.

25^2=7^2+y^2\\y^2=25^2-7^2\\y^2=576\\y=\sqrt{576}\\y=24

In the smaller right triangle with hypotenuse, x

Base = 7-3 =4 Units

Height, y= 24 Units

Therefore, applying Pythagoras Theorem.:

x^2=24^2+4^2\\x^2=592\\x=\sqrt{592}\\ x=4\sqrt{37}

Solve the system by graphing. Tell whether the system has one​ solution, infinitely many​ solutions, or no solution.
masha68 [24]
Here: 6y = 6x + 12
6y - 6x = 12

Divide by 6, 
y - x = 2
Which is nothing but first equation!

In short, Your Answer would be: "Infinitely Many solutions"
[ As L.H.S = R.H.S ]

Hope this helps!

Find the derivative of f(x) = 7x + 9 at x = 6
slava [35]
F(x)=7x+9
f´(x)=7
f´(6)=7

answer: f´(6)=7

f´(x)=Lim x⇒0   (f(x+h)-f(x)) / h
f´(6)=lim x⇒ 0   (7(6+h)+9 -(7*6+9)) / h
=lim x⇒0 ( 42+7h+9-42-9) /h
=lim x⇒0 (7h/h)=7

answer: f´(6)=7

How do you solve a supplementary equation
Rama09 [41]

Answer:Two angles are supplementary. If the measure of the angle is twice the measure of the other, find the measure of each angle.

Let the measure of one of the supplementary angles be a .

Measure of the other angle is 2 times a .

So, measure of the other angle is 2a .

If the sum of the measures of two angles is 180° , then the angles are supplementary.

So, a+2a=180°

Simplify.

3a=180°

To isolate a , divide both sides of the equation by 3 .

3a3=180°3a=60°

The measure of the second angle is,

2a=2×60°=120°

So, the measures of the two supplementary angles are 60° and 120° .

Example 2:

Find m∠Pandm∠Q if ∠Pand∠Q are supplementary, m∠P=2x+15 , and m∠Q=5x−38 .

The sum of the measures of two supplementary angles is 180° .

So, m∠P+m∠Q=180°

Substitute 2x+15 for m∠P and 5x−38 for m∠Q .

2x+15+5x−38=180°

Combine the like terms. We get:

7x−23=180°

Add 23 to both the sides. We get:

7x=203°

Divide both the sides by 7 .

7x7=203°7

Simplify.

x=29°

To find m∠P , substitute 29 for x in 2x+15 .

2(29)+15=58+15

Simplify.

58+15=73

So, m∠P=73° .

To find m∠Q , substitute 29 for x in 5x−38 .

5(29)−38=145−38

Simplify.

145−38=107

So, m∠Q=107° .
