[Right Triangles Only] sin∅ = opposite over hypotenuse [Right Triangles Only] cos∅ = adjacent over hypotenuseStep-by-step explanation:
Step 1: Define
We are given a right triangle. We can use trig to solve for the missing side length.
Step 2: Set up ratios
We can choose between the 2 angles and have multiple ratios to solve for x.
sin33° = x/51
cos57° = x/51
Hence, we see that the 1st option would be the correct answer.

Explanation:
Start at x = 3 on the x axis. Move up until you reach g(x), then move to the left to hit the y axis. You should arrive at y = 3.
That y value is the input to the f(x) function.
Plugging x = 3 into the f(x) function has us draw a vertical line down to f(x) and then go horizontally until we reach y = -2.

What is the difference of the polynomials? (9x^2 + 8) = (2x^2 + 3x)?
Answers
Answer:
7x^(2) - 3x + 8
Step-by-step explanation:
(9x^(2) + 8) - (2x^(2) + 3x)
distribute the "-" sign.
9x^(2) + 8 - 2x^(2) - 3x
Now combine like terms; (an "x^(2)" goes with an "x^(2)", not with an "x")
9x^(2) - 2x^(2) -3x + 8

karl filled up the tank of his truck with 400 liters of fuel and set out to deliver a shipment of bananas to alaska. the truck consumed 0.8 liters of fuel for each kilometer driven.
Answers
The graph of the relationship between the amount of fuel remaining in the trucks tank (in liters) and distance driven (in kilometers) is a linear equation given by, y = 400 - 0.8x
Given that Karl filled up the tank with 400 liters of fuel initially.
As time passes and more distance is covered, the amount of fuel will decrease. Thus the amount remaining is inversely proportional to the distance driven.
Let 'x' be the distance driven (in kilometers) by the truck and 'y' be the remaining fuel (in liters) in the tank.
It says that the truck consumes 0.8 liters of fuel for each kilometer driven.
Then the linear equation modelling this will be :
y = 400 - 0.8x
The graph can be drawn with values of 'x' on the x-axis and the values 'y' on the y-axis.

The points (-7,8) and (-11, -13) are the endpoints of a diameter on circle P. What is the length of the diameter of circle P? Round to the nearest tenth.
Answers
The lenght of the diameter of the circle P is 6.4
To solve this particular sum we need to know the concept of Distance formula . Distance formula is nothing but calculating the lenght of a line segment which has two end points .There are various types of distance formulas which we can use to calculate various things.
The different types of distance formulas are :
Distance between 2 points in a 2D Distance between 2 points in a 3D Distance between from a point to plane Distance between two parallel linesThe distance formula is : √{(x₂-x₁)² + (y₂-y₁)²}
Using this formula we will be able to find out the lenght of diameter of the circle P where endpoints are given as (-7,8) and (-11,-13)
(x₁,y₁) = (-7,8)
(x₂,y₂) = (-11,-13)
Substituting the values of x₁,y₁,x₂,y₂ in the formula we will get
∴ √{(-11+7)²+(-13+8)²}
= √{(-4)²+ (-5)²}
= √{16+25}
= √41
= 6.403
= 6.4 (rounded of to the nearest tenth)

A certain game gives scores between 0 and 5.
Trinity played 6 times and her mean score was 4.5.
Jayden played 4 times. If both players have the same
sum of scores, what was Jayden’s mean score?
Answers
Answer:
The mean value of Jayden is 6.75 .
Step-by-step explanation:
Given that the formula for mean is (total sum of scores) ÷ (total number of times). So first, we have to find the total sum of scores that Trinity gets :
[tex] \frac{total \: scores}{6} = 4.5[/tex]
[tex]total \: scores = 4.5 \times 6[/tex]
[tex]total \: scores \: = 27[/tex]
Assuming that Jayden also gets the score of 27 and played only 4 times so we have to find the Jayden's mean value :
[tex]mean = \frac{27}{4} [/tex]
[tex] mean = 6.75[/tex]

What is the surface area of the cuboid?
Answers
Answer:
Step-by-step explanation:
remember that the surface area is
S=2lw+2lh+2hw
S=2(15*20)+2(15*8)+2(8*20)=600+240+320=1160 cm^2
The surface area of the cuboid is 1160 square cm whose dimensions are
l= 20cm, w= 8 cm and h = 15 cm.
Given:
Length = 20 cm
width = 8 cm
Height = 15 cm
So, the formula for Surface area of Cuboid is
= 2(lw+ wh + lh)
Substituting the values l= 20cm, w= 8 cm and h = 15 cm into the formula as
= 2(lw+ wh + lh)
= 2 (20 x 15 + 8 x 15 + 8 x 20)
= 2 (300 + 120 + 160)
= 2 (580)
= 1160 square cm
