Answer:

f(7) = 158

Step-by-step explanation:

To evaluate f(7) substitute t = 7 into f(t)

f(7) = 3(7)² + 11 = (3 × 49) + 11 = 147 + 11 = 158

Answer: f(7) = 158

Step-by-step explanation:

f(t)=3t^2+11 find f(7)...... this can be gotten by inputting the function of 't' into the given equation i.e.

f(t) = f(7)

t = 7, so therefore

f(7) = 3t² + 11

f(t) = 3(7)² + 11

    = 3(49) + 11

    = 147 + 11

f(7) = 158

The model below represents the equation 3x+2=2x-5,
Leno4ka [110]

Step-by-step explanation:

Hey there!

The equation is;

3x + 2 = 2x - 5

Shifting "2x" to left side and "2" to right side.

3x - 2x =  - 5 - 2

Simplify them to get answer.

x =  - 7

Therefore the value of x is -7.

<u>Check</u><u>;</u>

3 × -7 + 2 = 2 × -7 -5

-19 = -19 ( True ).

So, your answer is option B.

A solid silver paperweight in the form of a square pyramid is shown below. If silver costs $0.12 per cubic centimeter, how much
Rufina [12.5K]

Answer:

It would cost $232.32, this answer is rounded.

Step-by-step explanation:

The formula for the volume of a square pyramid is:

V=a^2\frac{h}{3}

So its just:

8.8^2\frac{12.5}{3} = 322.67 cm^3

Then you just multiply the volume by the cost per cubic centimetre:

322.67cm^3*$0.12=$38.704

After just multiply the cost of one by how many you want, which is 6:

38/704*6=232.32
