Answer:

yes, brother can go

Step-by-step explanation:

Apparently, you're not to think to deeply about this function. Rather, you are to take the question at face value. It is asking if the value of T(3) is more than 58.

Evaluation of polynomials is facilitated by writing them in "Horner form."

T(x) = ((x -2)x +1)x^2 +27

T(3) = ((3 -2)3 +1)9 +27 = (3 +1)9 +27 = 36 +27

T(3) = 63

The coldest temperature is supposed to be 63 degrees, which is above 58 degrees. Baby brother can come along.

A cone has a diameter of 30 in. and a slant height of 17 in.

Use the given formula :

$V=\frac{1}3\pi r^2h=\frac{1}3\pi (\frac{D}2)^2h$ where $D$ is the diameter.

By Pythagoras, $h=\sqrt{17^2-(30/2)^2}=8\text{ in}$

Hence $V\approx\frac{3.14}3*15^2*8=\boxed{1884.0\text{ in}^3}$

In your top dresser drawer are 6 blue socks and 10 grey socks, unpaired and mixed up. one dark morning you pull two socks from t

beks73 [17]

We'll use the formula for the classical probability as follows.

P(A) = Number of outcomes favorable for A / Total number of possible outcomes

In this case, two socks are randomly drawn from a set of 6+10 = 16 socks. So the total number of possible outcomes = 16C2 = 120.

The two stocks match each other if they are both blue or grey. So the number of favorable outcomes is 6C2 + 10C2 = 15 + 45 = 60.

Hence the probability that the two stocks match is $\frac{60}{120}=0.5$ .
