I don't know how to do this. Any help?

Brut [27]

Answer:

cos 37=x/b (second one)

sin 37= a/b (third one)

tan 37=a/x (sixth one)

Step-by-step explanation:

Cos is defined by the adjacent side over the hypotenuse. Cos 37 would be x/b. Clearly, that is option 2. Sin is defined by opposite over hypotenuse. Sin 37 would be a/b. That is the 3rd option. Tan is defined by opposite over adjacent. Tan 37 would be a/x or the 6th option.

Which expressions below are equivalent to

Yuri [45]

Answer:

Step-by-step explanation:

2(2x + 1) = (2)(2x) + (2)(1) = 4x + 2 → A

used distributive property

2(2x + 1) = 2(1 + 2x) → B

used commutative property

2(2x + 1) = (2x + 1) + (2x + 1) = 2x + 1 + 2x + 1 → D

used 2a = a + a

2(2x + 1) = 4x + 2 = x + x + x + x + 1 + 1 → E

used 4x = x + x + x + x and 2 = 1 + 1

At a sale, suits were sold for $116 each. This price was 58% of a suit's original price. How much did a suit originally cost?

Fudgin [204]

To find the original price first put the % into decimal form.

58% is 0.58.

Then divide the discounted price ($116) by the % in decimal form:

116 / 0.58

Original price is $200.00

Answer the question bellow

Wittaler [7]

Answer:

The old version awards 50 more points for each level

Step-by-step explanation:

Function Modeling

Two models are being compared: The old model relates the total number of points awarded in a computer game (y) with the number of levels completed (x) as

$y=175x+150$

The new model is given as a graph. To find the equation of the line we must locate a couple of 'good' points. The graph is very clear, so we select the extreme points (1,250) (9,1250)

Find the equation of the line with the point-point formula

$\displaystyle y-250=\frac{1250-250}{9-1}(x-1)$

$\displaystyle y-250=\frac{1000}{8}(x-1)$

$y=250+125x-125$

$y=125x+125$

Comparing the new function with the old function we can note the coefficient of x (the slope of the line) is 50 points more in the old version than the points in the new version.

Thus the answer is

The old version awards 50 more points for each level
