The rectangles below are similar in shape. How wide is the smaller rectangle?
Answer:
[tex]\huge\boxed{x=28\ ft}[/tex]
Step-by-step explanation:
If two rectangles are similar, then corresponding sides are in proportion.
Therefore we have the equation:
[tex]\dfrac{x}{42}=\dfrac{36}{54}[/tex]
cross multiply
[tex]54x=(42)(36)\\\\54x=1512[/tex]
divide both sides by 54
[tex]\dfrac{54x}{54}=\dfrac{15212}{54}\\\\x=28[/tex]
Find the slope of the line that passes through the points (1,-4) and (3,-1).
Answer:
The answer is
[tex] \frac{3}{2} \\ [/tex]
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(1,-4) and (3,-1)
The slope is
[tex]m = \frac{ - 1 - - 4}{3 - 1} = \frac{ - 1 + 4}{2} = \frac{3}{2} \\ [/tex]
We have the final answer as
[tex] \frac{3}{2} \\ [/tex]

Square root of 56 is between what two whole numbers
Answer:
14
Step-by-step explanation:
Answer:
[tex]\huge\boxed{7,8}[/tex]
Step-by-step explanation:
In order to find what two numbers [tex]\sqrt{56}[/tex] is between, we need to find two numbers that, when squared, get us close to 56.
Let's see. We know that [tex]7^2 = 49[/tex]. We also know that [tex]8^2 = 64[/tex]
We know that 56 is in between 7 and 8's squares - 49 and 64. This means that [tex]\sqrt{56}[/tex] will be in between [tex]7^2[/tex] and [tex]8^2[/tex].

Which of the following statements about the function cannot be used to conclude that is defined at x = 1?
a) lim x—>1 f(x) exists
b) f is continuous at x = 1
c) f is differentiable at x = 1
d) the line tangent line to the graph of f at x=1 exists
a) [tex]\lim_{x \to 1} f(x)[/tex] exists
As the limit of a function at any certain point can exist, but the function itself may be not defined at that point.
For example, if [tex]f(x) =\frac{ (x^3 - 1) }{(x - 1)}[/tex], then [tex]\lim_{x \to 1}\frac{(x^3 - 1)}{ (x - 1)} = 3[/tex],
So, here f(1) is undefined as there is a hole in the graph of the function f(x) at the point (1,3).
Therefore the correct statement about the function cannot be used to conclude that is defined at x = 1 is [tex]\lim_{x \to 1} f(x)[/tex] exists.

use the following functions: yf(x) = 3x - 7
g(x) = 2x - 4
1. Find (f + g)(x).
2. Find (f - g)(x).
Answer:
(f + g) (x) = 5x - 11
(f - g) (x) = x + 3
Step-by-step explanation:
f(x) = 3x - 7
g(x) = 2x - 4
to find ; (f + g) (x) and (f - g) (x)
now,
(f + g ) (x) = f (x) + g(x)
= (3x - 7) +( 2x - 4 )
= 3x - 7 + 2x - 4
= 5x - 11
again ,
(f - g ) (x) = f(x) - g(x)
= (3x - 7) - (2x - 4)
= 3x - 7 - 2x + 4
= x + 3

Which of the following is true about the charge of an electron?
a. It is 1.602 x 10^-19 C, and the smallest unit of charge
b. It is -1.602 x 10^-19 C, and the smallest unit of charge (THIS ANSWER IS CORRECT)
c. It is -1.602 x 10^-19, and it is a multiple of the smallest unit of charge
d. It is 1.602 x 10^-19, and it is a multiple of the smallest unit of charge
Answer:
It is -1.602 x 10^-19 C, and the smallest unit of charge
Step-by-step explanation:
The charge on an electron is [tex]1.6\times 10^{-19}\ C[/tex]. The charge on electron is negative. The quantization of electric charge is :
q = ne
q is net charge
n is no of electrons
e is the electronic charge which is [tex]-1.6\times 10^{-19}\ C[/tex]. Hence, the correct option is (b).

Answer:
m∠1= 110
m∠2= 39
m∠3= 31
Step-by-step explanation:
All of these angles would sum up to 360 degrees, but due to half of the angles missing, then we can only do half at a time.
First, the angles given are m∠4, m∠5, and m∠6. Which are:
m∠4= 90
m∠5= 59
m∠6= 31
So, we need to find m∠1. To do so, the equation would be: m∠5+m∠6+m∠1= 180
Step 1- Substitute into the equation with the information given.
59+31+m∠1= 180
Step 2- Simplify.
90+m∠1= 180
Step 3- Subtract 90 to both sides.
90+m∠1= 180
-90 -90
m∠1= 110
So, now we know m∠1 which is 110 degrees.
Now, for m∠2 the equation would be: m∠1+m∠2+m∠6= 180
Substitute into the equation.
110+m∠2+31= 180
Step 1- Add to simplify,
141+m∠2= 180
Step 2- Subtract 141 to both sides.
141+m∠2= 180
-141 -141
m∠2= 39
Now we know most of them, and now we need m∠3.
The equation would be: m∠1+m∠2+m∠3= 180
Substitute the equation with the information given.
110+39+m∠3= 180
Step 1- Add to simplify.
149+m∠3= 180
Step 2- Subtract 149 to both sides.
149+m∠3= 180
-149 -149
m∠3= 31
Now we know all the angles!
Answer:
=90 degrees

what are the solutions to the equation (x-6)(x+8)=0?
Answer:
x = 6, -8
Step-by-step explanation:
If (x - 6)(x + 8) = 0, that would imply that either (x - 6) or (x + 8) would equal zero. Using this, we can find that solving the two equations:
x - 6 = 0
and
x + 8 = 0
would yield the two solutions to the equation.
x - 6 = 0
Add 6 to both sides of the equation.
x = 6
So one of the solutions would be x = 6.
x + 8 = 0
Subtract 8 from both sides of the equation.
x = -8
So the other solution would be x = -8.
The two solutions are x = 6 and x = -8.
I hope you find my answer and explanation to be helpful. Happy studying.

Give the equation of the line with a slope of
1
7
and a y-intercept of 1.
Answer:
y = 17x + 1
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m = slope
b = y-intercept
Answer:
y=17x+1
Step-by-step explanation:
When a question asks us to give the equation of a line, we usually organize it into this formula:
y=mx+b
This formula is called slope-intercept form. Here's what the variables mean:
y=the y-axis
m=the slope
x=the x-axis
b=the point on the line that crosses the y-axis (the y-intercept)
So to write an equation of a line with a slope of 17 and a y-intercept of 1, we would need to plug those values in as m and b.
y=17x+1
I hope this helps! Please comment if you have any questions.
