f(x)=x^2-3x+4

\\ \sf\longmapsto f(-2)

\\ \sf\longmapsto (-2)^2-3(-2)+4

\\ \sf\longmapsto 4+6+4

\\ \sf\longmapsto 10+4

\\ \sf\longmapsto 14

I don’t know wich boxes to choose
Anika [276]

Answer:

C, D, F

Step-by-step explanation:

She walked 12 miles. Then she walked 1/4 that distance. "That distance" is 12 miles.

That means she walked 12 miles plus 1/4 of 12 miles.

She walked

12 + 1/4 * 12

You can factor out 12 from the expression above, and write it as

12(1 + 1/4)

Now you can do the addition in parentheses.

12(1 + 1/4) = 12(4/4 + 1/4) = 12(5/4)

Answer:

C, D, F

It took a submarine 30 seconds to sink 225 feet, moving at a constant speed. The captain wants to know the submarine's speed.
Vladimir [108]

Answer:

Speed per second= 7.5 feet per second

Step-by-step explanation:

Giving the following information:

We have a distance (225 feet), and a time (30 seconds). Also, we know that the speed was constant.

<u>All we have to do is divide the distance by the time and determine the speed per second:</u>

Speed per second= distance / time

Speed per second= 225 / 30

Speed per second= 7.5 feet per second

A coin is tossed and a die is rolled simultaneously. What is the probability of getting a tail and a number less than 3?
Reil [10]

Answer: 1/6

Step-by-step explanation:

Probability of getting heads or tail is:

P (H) = P(T) = 1/2

The probability of getting any number on the die is:

P (1) = P (2) = P(3) = P (4) = P (5) = P (6) = 1/6

The probability of getting a tail on the coin and a number less than 3 on the die is:

P($Tails and a number less than 3$)=P($Tails$) \times P$(A number less than 3)$$\begin{aligned}&=\frac{1}{2} \times[P(1)+P(2)] \\&=\frac{1}{2} \times\left[\frac{1}{6}+\frac{1}{6}\right] \\&=\frac{1}{6}\end{aligned}$$

Therefore the required of getting tails and a number less than 3 is 1/6
