Answer:
Slope= 2 ; y intercept= 4
Step-by-step explanation:
Slope: (y2 - y1)/(x2-x1) where x and y indicate the coordinates of two points
Slope = (4-0)/(0-(-2) = 4/2 = 2
y intercept is where the line intercepts the y axis: it happens in (0;4)
Answer:
y intercept is 4 and slope is 2

The rectangular prism has a volume of 936 cubic inches. Write and solve an equation to find the missing dimension of the prism.
Step-by-step explanation:
A rectangular prism is nothing but a cuboid. Let the length , width and height of the rectangular prism be l, w and h.
We know that volume of a cuboid V = l×w×h
So, l×w×h = 936
So, we can find any dimension of the prism provided the the other two dimensions are given to us.

One of the legs of a right triangle measures 7 cm and the other leg measures 3 cm.
Find the measure of the hypotenuse. If necessary, round to the nearest tenth.
Answer:
about 7.6
Step-by-step explanation:
I got the measure of the hypotenuse to be about 7.6 because I did the Pythagorean theorem.
a^2+b^2=c^2
The value of a is the first leg (7cm), and the value of b is the second leg (3cm).
So, 7^2+3^2=58. Next, I found the square root of 58. The square root of 58 is 7.615773106. This value rounded to the nearest tenth is 7.6.
In conclusion, the measure of the hypotenuse rounded to the nearest tenth is about 7.6.

Step-by-step explanation:
(3)×3 - 2×(-2)×(1) + 5×(3)×(1)
9 - -4 + 15 = 28
Answer:
46
Step-by-step explanation:
Given
a³ - 2bc + 5ac ← substitute values for a, b, c into the expression
= 3³ - (2 × - 2 × 1) + (5 × 3 × 1)
= 27 - (- 4) + 15

Find the trigonometric ratio as a fraction Tan N =
Find the trigonometric ratio as a fraction Tan L =
Answer:
Tan N = 4 / 3
Tan L = 3 / 4
Step-by-step explanation:
By Pythagoras theorem,
(LN)² = (MN)² + (LM)²
10² = 6² + (LM)²
100 = 36 + (LM)²
(LM)² = 100 - 36
(LM)² = 64
LM = 8
Tan N
= Opposite / Adjacent
= LM / MN
= 8 / 6
= 4 / 3
Tan L
= 1 / Tan N
= 1 / ( 4 / 3 )
= 3 / 4

Direction: Determine whether each pair of triangles is congruent by SSS, SAS, ASAor AAS. If it is not possible to prove that they are congruent, wnte NOT POSSIBLE
Step-by-step explanation:
SSS axiomSAS axiomASA axiomASA axiomSAS axiomSSS axiomWhich graph represents a reflection of f(x) = 2(0.4)x across the y-axis? On a coordinate plane, an exponential function approaches y = 0 in quadrant 2 and increases into quadrant 1. It crosses the y-axis at (0, 2) and goes through (1, 5). On a coordinate plane, an exponential function decreases from quadrant 3 to quadrant 4 and approaches y = 0 in quadrant 3. It crosses the y-axis at (0, negative 2) and goes through (1, negative 5). On a coordinate plane, an exponential function decreases from quadrant 2 to quadrant 1 and approaches y = 0 in the first quadrant. It goes through the y-axis at (0, 2) and goes through (negative 1, 5). On a coordinate plane, an exponential function increases from quadrant 3 to quadrant 4 and approaches y = 0. It goes through (negative 1, negative 5) and crosses the y-axis at (0, negative 2).
The graph of g(x) is (a) an exponential function approaches y = 0 in quadrant 2 and increases into quadrant 1. It crosses the y-axis at (0, 2) and goes through (1, 5).
The function f(x) is given as:
[tex]f(x) = 2(0.4)^x[/tex]
The rule of reflection over the y-axis is:[tex](x,y) \to (-x,y)[/tex]
This means that:
[tex]g(x) =f(-x)[/tex]
Substitute -x for x in f(x)[tex]f(-x) = 2(0.4)^{-x}[/tex]
Substitute the expression for f(-x) in the above equation [tex]g(x) =f(-x)[/tex][tex]g(x) = 2(0.4)^{-x}[/tex]
Hence, the graph of g(x) is graph (a)

A fast-food restaurant must apply an 8.5% tax on every sale it makes. How much tax must it charge a customer who purchases a total of $18.50 in food?
Answer: $1.57
Step-by-Step Explanation:
Study.com says: “the formula for calculating the sales tax on a good or service is: selling price x sales tax rate, and when calculating the total cost of a purchase, the formula is: total sale amount = selling price + sales tax,” (study.com, How to Calculate Sales Tax).
So, to find the amount of money they are charging for taxes, we need to use the formula: $18.50 x 8.5%. The selling price is the total sum of the purchase, and the sales tax rate is the percentage number that is apply to every sale as taxes.
Here’s how we solve:
1. To multiply, we first need to change our percentage into a decimal by dividing it by 100. —> 8.5/100 = 0.085
2. Multiply the purchase times the sales tax rate, which is converted into a decimal. —> 18.50 x 0.085 = 1.5725
3. Because money only uses the tenths and the hundredths places, we round up. —> 1.5725 ~ 1.573 ~ 1.57
4. Our answer for the tax amount charged in money is $1.57

HELP I don’t understand
Answer:
144, 36
Step-by-step explanation:
you know that if you add the two angles it will equal 180 degrees. so add the two angles and make them equal to 180 and solve for x.
(4x+8) + (x+2)=180
5x+10=180
5x=180-10
5x=170
x=34
now replace x in each equation:
4(34)+8=144
34+2=36
11. The ratio of men to women at a track meet is 4:5. If there are 20 men at the meet, use a proportion to determine how many people are at the meet.
Answer:
There are 36 people at the meet
Step-by-step explanation:
if the ratio is 4 men to 5 women it means that every time there are 4 men there will be 5 women so its 4/5
and since we know there are 20 men the equation becomes:
4/5 = x/20
so to make 4/5 have 20 as a denominator we multiply by 4/4.
4/5*4/4 = 16/20
So, now we know there are 16 women.
And 16+20 = 36

"hypotenuse" of the triangle: if the height is 24 feet and base is 36 feet.
Answer:
43.27
Step-by-step explanation:
(24×24)+(36×36)= 1872
√1872=43.27
Using the Pythagorean theorem:
Hypotenuse = sqrt( 24^2 + 36^2)
Hypotenuse = sqrt(576 + 1296)
Hypotenuse = sqrt(1872)
Hypotenuse = 2sqtt(469) or 43.266

Step-by-step explanation:
Assuming x is the length DB
Δ DSR and Δ DBC are similar, so ratios of corresponding sides are equal, that is
[tex]\frac{DB}{DS}[/tex] = [tex]\frac{DC}{DR}[/tex] , substitute values
[tex]\frac{DB}{10}[/tex] = [tex]\frac{12}{8}[/tex] ( cross- multiply )
8 DB = 120 ( divide both sides by 8 )
DB = 15
That is x = DB = 15
