Bas_tet [7]

Answer:

20.  300π m³

21.  457 1/3 π cm³

Step-by-step explanation:

20. r = 10 ÷ 2 = 5

V = 5² × 12 × π = 25 × 12π=300π m³

21. r = 14 ÷ 2 = 7

V = \frac{4}{3} \pi 7x^{3}

V = 457 1/3 π cm³

Solve the equation 6+(c+8)=136-(c+8)-131+7(t+2)=854(A+4)-9(A-4)=3711=7-(1-y)3+7(p-10)= -38-(5-3p)20+5(3-5A)=-5(A-6)+5
marissa [1.9K]

Let's solve the next equation:

6+(c+8)=13

We need to find the value for c, this value is correct when we replaced it with a number and the equality equation becomes true.

First, subtract both sides by 6

6-6+(c+8)=13-6c+8=7

Now, subtract both sides by 8

c+8-8=7-8c=-1

Replacing the c value to verify:

6+(-1+8)=136+7=13

The c value is correct.

Given f(x) = 2x + 1, find the range value if the domain value is 1.75.
MAXImum [283]

Given:

The function is

f(x)=2x+1

To find:

The range value if the domain value is 1.75.

Solution:

Domain is the set of input values and range is the set of output values.

Here, range value if the domain value is 1.75. It means the value of function f(x) at x=1.75.

Substitute x=1.75 in the given function.

f(1.75)=2(1.75)+1

f(1.75)=3.5+1

f(1.75)=4.5

Therefore, the required range value is 4.5.
