Answer:

Step-by-step explanation:

(0, 4) (2, 0)

(0-4)/(2-0) = -4/2 = -2

y - 4 = -2(x - 0)

y - 4 = -2x + 0

y = -2x + 4

Based on the data, select the most reasonable prediction about the height ofsecond-grade students.A. The typical second-grade student is less than 45 inches tall.B. The typical second-grade student is about 45 inches tall.C. The typical second-grade student is more than 50 inches tall.D. The typical second-grade student is about 48 inches tall.

Answers

second-gradeWe are given the following data set:

$44,45,47,49,48,48,49,50,48,52$

We can calculate the mean of this data set, by adding all the terms and dividing by the number of terms, that is 10:

$\text{mean}=(44+45+47+49+48+48+49+50+48+52)/(10)=(480)/(10)=48$

Since the mean is 48 this means that the typical second grade student is 48 inches tall. the right answer would be D.

A conical paper cup has a radius of 2 inches. Approximate, to the nearest degree, the angle β (see the figure) so that the cone will have a volume of 60 in3.β = °

Answers

The angle β (see the figure) so that the cone will have a volume of 60 in3 is 82.05 degrees

Volume of a cone

The formula for calculating the volume of a cone is expressed as:

V = 1/3πr²h

where

r is the radius

h is the height

Given the following

volume = 60

radius = 2

h = r tanβ

Substitute

V = 1/3πr²(r tanβ)

Substitute

60 = 1/3(3.14)(2)³tanβ

180 = 25.12tanβ

tanβ = 180/25.12

β = 82.05 degrees

Hence the angle β (see the figure) so that the cone will have a volume of 60 in3 is 82.05 degrees

I don't know where the angle β is, so I will make the assumption that tanβ = h/r
$V = (1)/(3) \pi r^(2) h$

V volume = 60
r radius = 2
h = r tanβ

$tan \beta = (3V )/( \pi r^(3) ) = ( 180)/(25,1) = 7,17 \n \n \beta = 82$

I would like to create a rectangular vegetable patch. The fencing for the east and west sides costs $4 per foot, and the fencing for the north and south sides costs only $2 per foot. I have a budget of $176 for the project. What are the dimensions of the vegetable patch with the largest area I can enclose?

Answers

x = E/W dimension
y = N/S dimension

4x + 4x + 2y + 2y = 64
8x + 4y = 64
4y = 64 - 8x
y = 16 - 2x

Area = xy = x(16 - 2x) = 16x - 2x^2

Maximum of y = ax^2 + bx + c is when x = -b / 2a

so x = -16 / -4 = 4
