Please help me A line that includes the point (3, 3) has a slope of 4. What
is its equation in slope-intercept form?
Answer:You can do this two ways: Either use the slope intercept form
y = mx + b with slope m=-2 so y = -2x +b
From that use x=5, y = -3 to solve for b
-3 = -2(5) + b
-3 = -10 + b
10-3 = b
7 = b
Your equation is: y = -2x + 7
OR
Use the point slope formula: y - y1 = m(x-x1)
with m = -2, (x1, y1) = (5,-3)
y-(-3) = -2(x-5)
y + 3 = -2x + 10
y = -2x + 10 - 3
y = -2x + 7
Step-by-step explanation:
is y=4 and x=8 perpendicular ??
Answer:
yes
Step-by-step explanation:
y=4 is a horizontal line which crosses the y-axis at 4; slope is zero
x=8 is a vertical line which crosses the x-axis at 8; slope is undefined

What is the area of a sector with radius 6" and measure of arc equal to 120°?
12 π sq. in.
36 π sq. in.
6 π sq. in.
4 π sq. in.
Answer:
12 π sq. in.
Step-by-step explanation:
Circumference c = 2πr
Arc Length s = [tex](\frac{0^0}{360^0})[/tex] (2πr)
s = [tex](\frac{120}{360})[/tex] * 2π * 6 = 4π = 12

please solve rhis ques
Answer:
The highest common factor is (a + b)
Step-by-step explanation:
We start by making a factorization of the first expression
By using the difference of two squares, we can have it as;
a^2 - b^2 = (a + b)(a-b)
For the second expression, we already have;
(a + b)^2 = (a + b)(a + b)
What this mean is that (a + b) is common to both expressions and we have it as the highest common factor
The length of one piece of string is 1/5m. What will be the total length of 4 such pieces of string?
Answer: [tex]\dfrac{4}{5}\ m[/tex]
Step-by-step explanation:
Given
The length of one piece of string is [tex]\frac{1}{5}\ m[/tex]
So, the length of 4 pieces is the addition of four-piece length.
[tex]\Rightarrow L=\dfrac{1}{5}+\dfrac{1}{5}+\dfrac{1}{5}+\dfrac{1}{5}\\\\\Rightarrow L=4\times \dfrac{1}{5}\\\\\Rightarrow L=\dfrac{4}{5}\ m[/tex]
What is the approximate 47? Give your answer and explain why it is correct. HELP
Answer:
7
Step-by-step explanation:
7 is approximate to [tex]\sqrt{47}[/tex] because 7 is [tex]\sqrt{49}[/tex], and 49 is close to 47
Answer:
Step-by-step explanation:
[tex]6^{2} =36\\7^2=49\\therefore,6< \sqrt{47} <7,\\6.5^2=42.25,\\therefore,6.5< \sqrt{47} <7,\\6.75^2=45.5625\\therefore,6.75< \sqrt{47} <7\\6.85^2=46.9225\\therefore,6.85< \sqrt{47} <7\\6.9^2=47.61\\therefore,6.85< \sqrt{47} <6.9[/tex]

A pendulum is constructed by attaching a 4m rope to a bowling ball. It is then displaced 2m to one side and released.
Ignoring all effects of friction, and without knots,
a) Determine the period of the pendulum. Round to one decimal place.
Answer:
T = 4.0 s
Step-by-step explanation:
The period of a simple pendulum is given by
[tex]period = 2\pi \sqrt{ \frac{l}{g} } [/tex]
where l = length of the pendulum
= 4 m
g = acceleration due to gravity
= 9.8 m/s^2
[tex]period = 2\pi \sqrt{ \frac{(4 \: m)}{(9.8 \: \frac{m}{ {s}^{2} } )} } = 4.0 \: s[/tex]

SA = 2pi * r ^ 2 + 2pi * r * h (Use 3.14 for .) How much metal is needed to create a trash can with a height of 4 feet and a base radius of 1 foot? (Find the surface area of the cylinder.) pi square feet Do NOT round your answer.
Answer:123
Step-by-step explanation:
The slideat the playground has a height of 6ft. The base of the slide measured on the ground is 8ft. What is the length of the slide?
Answer:
10 ft
Step-by-step explanation:
The length of the slide can be determined using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
6² + 8² =
36 + 64 = 100
c = √100
c = 10

The sides of a triangle are 3 consecutive odd integers and the shortest side is 20% of the perimeter of the triangle. What is the perimeter of the triangle?
Answer:
15 units
Step-by-step explanation:
The terms of an odd integer are given by 2n - 1. Since the sides of the triangle are three consecutive odd integers, let them be 2n - 1, 2(n + 1) - 1 and 2(n + 2) - 1 respectively, where 2n - 1 is the shortest side
Let P = perimeter of triangle = 2n - 1 + 2(n + 1) - 1 + 2(n + 2) - 1
= 2n - 1 + 2n + 2 - 1 + 2n + 4 - 1
= 2n - 1 + 2n + 1 + 2n + 3
= 2n + 2n + 2n - 1 + 1 + 3
= 6n + 3
Since the shortest side is 20% of the perimeter of the triangle, we have that
2n - 1 = 20%(6n + 3)
2n - 1 = 0.2(6n + 3)
expanding the bracket, we have
2n - 1 = 1.2n + 0.6
subtracting -1.2n and adding +1 to both sides, we have
2n - 1.2n = 1 + 0.6
0.8n = 1.6
dividing both sides by 0.8, we have
n = 1.6/0.8
n = 2
Since P = 6n + 3, substituting n = 2, we have
P = 6(2) + 3 = 12 + 3 = 15 units

Rebecca paid $16.90 to place an advertisement in a local
newspaper. The newspaper charged $4.50 set up fee and $0.40
per word. How many words were in Rebecca's advertisement?
Answer:
31 words
Step-by-step explanation:
because the set up fee is 4:50$, minus this from the price Rebecca payed
16.90-4.50=$12.40
now divide this amount by $0.40 in order to get her word count
12.40÷0.40=31

Find a pair of complementary angles. Show work to prove they are complementary.
Answer:
Hello! answer: 45 and 45 is a complementary angle and 60 and 30 is a complementary angle
Step-by-step explanation:
Complementary angles are just angles that add up to 90 degrees so... 45 + 45 = 90 60 + 30 = 90 so that is how those are complementary angles.
Hope that helps!
Answer:
angle QRT/angle VRT and angle SRW/angle WRV
Step-by-step explanation:
QRT and VRT: Both angles are 45 degrees, adding those degrees together gets you 90 degree angles meaning that they are complementary.
SRW and WRV: 60 plus 30 is equal to 90 making them complementary angles as right angles are 90 degrees
Lupe needs to make a poster that is 2 m by 4 m for the big game. The cost of the paper is $1.75. Later she needs another poster with dimensions 1 m by 2 m. What is the paper for this poster likely to cost
Answer:
$0.42
Step-by-step explanation:
Given data
Dimension
Length=4m
Width=2m
Cost= $1.75
Area= 4*2= 8m^2
Cost per area=1.75/8
Cost per area=$0.21 per m^2
The new poster's dimension
Lenght =2m
Width= 1m
Area= 2*1= 2m^2
Hence if a square meter cost $0.21
Then 2 square meter will cost x
cross multiply
2*0.21=x
x=$0.42
Hence the new poster will cost $0.42
