Katherine wants to construct a small box with a volume of 20 cubic inches with the following specifications. The length of a box

pochemuha

V=LWH=20

L is 5 more than W
V=5+W

H is 1 less than W
H=-1+W

easy, sub 5+W for L and -1+W for H in LWH=V=20

20=(5+W)(W)(-1+W)
expand
20=W^3+4W^2-5W
minus 20 both sides
W^3+4W^2-5W-20=0
either factor or graph to find the possible values for W
(W+4)(W^2-5)=0
set each to zero

W+4=0
W=-4
impossible, measures cannot be negative
W^2-5=0
add 5
W^2=5
sqrt both sides
W=√5

sub back

L=5+W
L=5+√5
aprox
7.24 rounded

H=-1+W
H=-1+√5

the dimentions are

Find an equation of the line described below. Write the equation in slope-intercept form (solved for y), when possible.

Vinil7 [7]

Answer:

<em>y=-x+18</em>

Step-by-step explanation:

<u>Equation of a line</u>

A line can be completely defined by two points. Suppose we know the line passes through points A(x1,y1) and B(x2,y2).

The equation for a line can be written as:

$y=mx+b$

Where m is the slope and b is the y-intercept. Both values can be determined by using the coordinates of the given points.

First, determine the slope with the equation:

$\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

The points are: A(15,3) B(3,15)

$\displaystyle m=\frac{15-3}{3-15}=\frac{12}{-12}=-1$

The equation of the line can be written as:

$y=-x+b$

Now, use any point to determine the value of b. Substitute (15,3):

$3=-15+b$

Solve for b:

b=18

The equation of the line is

y=-x+18

The slope is -1 and the y-intercept is 18.

Pamela's age is three times Jiri's age. The sum of their ages is 20 . What is Jiri's age?

navik [9.2K]

Answer: Jiří is 5 years old.

Step by step:

Let x denote Jiří's age in years. Then Pamela's age is 3x. Their sum is x + 3x = 20. So we solve for x:

x + 3x = 20

4x = 20

x = 5

Jiří's age is 5 years
