Find f(–2) for the function f(x) = 3x2 – 2x + 7. −13 −1 1 23

Answers

Answer:

The correct option is 4. The value of f(-2) is 23.

Step-by-step explanation:

The given function is

$f(x)=3x^2-2x+7$

We have to find the value of f(-2). It means we need to find the value of function f(x) at x=-2.

Substitute x=-2 in the given function to find the value of f(-2).

$f(-2)=3(-2)^2-2(-2)+7$

On simplification we get

$f(-2)=3(4)-(-4)+7$

$f(-2)=12+4+7$

$f(-2)=23$

The value of f(-2) is 23. Therefore the correct option is 4.

Answer:

f(-2) = 23

Step-by-step explanation:

$f(x)=3x^2-2x+7\n\nf(-2)\to\text{put x = -2 to the equation of a function:}\n\nf(-2)=3(-2)^2-2(-2)+7=3(4)+4+7=12+4+7=23$

In a stairway, the slope of the handrail is the ratio of the riser to the tread. If the tread is 12 inches long and the riser is 8 inches long, find the slope.(image)

a.
2/5
c.
2/3
b.
3/2
d.
5/2

Answers

The slope of the handrail is 2/3. The correct answer is: c. 2/3

To find the slope of the handrail, we can use the given information that the slope is the ratio of the riser to the tread.

Slope = Riser / Tread

Given that the tread is 12 inches long (Tread = 12 inches) and the riser is 8 inches long (Riser = 8 inches), we can substitute these values into the formula:

Slope = 8 inches / 12 inches

Now, we can simplify the ratio:

Slope = 2/3

So, the slope of the handrail is 2/3. The correct answer is:

c. 2/3

What times what equals 78 and what times what equals 125 please explain !!!

Answers

Well, a good way to find out is that 78 goes into 3, because if you add 7 and 8 you get 15 and 15 goes into 3, so if you divide 78 by 3 you get 26 , and 125 goes into 25 so if you take 125 divided by 25, you get 5. So your 2 answers are 3*26=78, and 25*5=125

For number 16 we need to write the data as a ratio then convert to a unit rate (amount per 1)...

308/14 = x/1

Cross multiply

14x = 308
x = 308/14
x = 22

So the fuel efficiency is
22 miles per 1 gallon or

22/1

For number 17, since the car was driven at 48 mph, we just have to divide distance driven by speed to get how long it took...

288 miles ÷ 48 mph =

6 hours
