16) Jenna is responsible for changing the broken light bulb in a streetlamp. The streetlamp is 14 feet high. Jenna places the base of her ladder 3 feet from the base of the streetlamp. Jenna can extend the ladder from 10 feet to 14 feet. How long must her ladder be to reach the top of the streetlamp? Will her ladder work?
Use the Pythagorean theorem:
Height is 14, base is 3, so we can calculate the length required.
Length = sqrt(14^2 + 3^2)
Length = sqrt( 196 + 9)
Length = sqrt(205)
Length = 14.32 feet.
The ladder needs to be 14.32 feet. The longest her ladder can be is 14 feet so her ladder won’t work.
Answer:
14.32 is ur awnser

y=x^2-3, what is your y value when x=4
Answer:
13
Step-by-step explanation:
4^2 is 16
16-3=13
that's all that you have to do you replace the x with 4 and do a normal equation
Answer: y=13
Y=(4)^2-3
y=16-3
y=13

A cylinder has a diameter of 18cm and a height of 4cm.
The radius is 12cm
The volume of the cylinder is324 п cm
The volume of the cylinder is1296 п cm
The area of the base of the cylinder is 81 п cm?
Answer:
The volume of the cylinder is324 п cm
The area of the base of the cylinder is 81 п cm
Step-by-step explanation:
volume of a cylinder = nr^2h
n = 22/7
r = radius = 18/2 = 9
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
n x (9^2) x 4 = 324n
Area of the base of the cylinder : Area of a circle = πr² = π x 9^2 = 81 π

What is the distance between two points(0,0)(-3,5)
Step-by-step explanation:
Think of it like a right triangle. Do you have a graph handy?
Ok, graph both of the points. Now connect the points. That's our hypotenuse and the side length we want to find.
Now, bring down a line from (-3,5) to the x axis. Do you see a right triangle?
All we have to do is find the hypotenuse of this right triangle we just drew. We already have the leg lengths which are 3 and 5. Using this, do the pythagorean theorem.
9+25=34
√34 is our hypotenuse & distance between the points

Find the measure of the label angles below note: you must find y first
13
124
6.8
68.2
Answer:
124°
Step-by-step explanation:
since they are vertical angles, then put them equal to eachother
9y + 7 = 2y + 98
7y = 91
y = 13
9(7)+7= 124
2(13)+98= 124

Answer:
SO first we need to get our numbers.
WE see 20.9 and 10.We learned in school that when
you multiply decimals itll show the placr its in.
So it basically shows you the answer.
Now lets divide, 20.9 divided by 10=2.09

Find the measure of angle b. PLZ HELP AND SHOW WORK
Answer:
1) A because of vertical angle theorem (VAT), which means that b=37 degrees
2) C because a right angle is= to 90 degrees. Take away 23, you get 67 degrees
3) B because the image shows a full angle, which is equal to 360 degrees. Take away 207 and 58, you get 95 degrees
4) D because a right angle is= to 90 degrees. Take away 44, you get 46 degrees
5) A because a right angle is=to 90 degrees. Take away 58, you get 32 degrees

Solve for x.
2x + 24
3x - 26
x = [?]
Answer:
set them equal to eachother, i gotta look at my notes tho
Step-by-step explanation:
I think it's like this
3x-26=2x+24
We simpilfy the equation to the form which is simple to understand.
3x-26=2x+24
We move allterms containing X to the left and all others terms to the right
+3x-2x=+24+26
We simplfiy left and right sideof the eqution.
+1x=+50
We divide both sides of the equation by 1 to get x.
x=50
