A cone has a radius of 1.2 and a height of 2.9 inches. What is the volume, to the nearest tenth of a cubic inch, of the cone?. E

Mademuasel [1]

Answer:

4.4 cubic inches

Step-by-step explanation:

From the question;

Radius of the cone is 1.2 inches
Height of the cone is 2.9 inches

We are required to determine the volume of a cone;

Volume of a cone is given by the formula;

V=1/3πr²h

Therefore; taking π to be 3.142

Volume =1/3 × 3.142 × 1.2² × 2.9

= 4.373664

= 4.4 cubic inches (to the nearest tenth)

Thus, the volume of a cone is 4.4 cubic inches

Guys, please help! I'm reaallllyyyy desperate!

Answer:

So first, let's substiute the variables into numbers based on your problem. We get -(-1)-(5)^2+3(-1)(5). If we solve that expression, we will get -39. So, your answer is -39. Hope this helps and good luck

Answer:

See below

Step-by-step explanation:

1. (refresh if you cant see it)

$F = \frac{9}{5}C+32\\\text{Bring variable C to left side}\\-\frac{9}{5}C=-F+32\\\text{Multiply by -1}\\\frac{9}{5}C=F-32\\\text{Multiply the equation by 5/9 to get C by itself}\\C = \frac{5}{9}(F-32)$

2(x + 3) = 20

Distribute.

2x + 6 = 20 $\neq$ 2x + 3 = 20

Your answer is false.

x $\geq$ -2 because even though it includes the expression "x>5", those values are also above -2, including 5.

Step-by-step explanation:

<u>Modeling With Functions </u>

We have a table of values of speeds vs distance taken for a car to stop. We are required to find a model that uses the square root and fits the given data to predict other values of d as a function of v.

By the nature of the problem, we can know that for v=0, d must be 0 too. So our model won't include a vertical shift or independent term. Being v the speed of the car and x the distance it takes to stop, we use the following model

$x(v)=A\sqrt{v}$
