Oh my gosh...thats a lot. Umm, well let's start with what the equation says. This will break it down to where it's of better understanding. What is the equation asking you to do? You have heard of the acronym "PEMDAS", correct? (Parantheses, Exponents, Multiplication, Division, Addition and Subtraction) Follow that order of operations and see what it is the equation wants done first. Solve it, basically...then we will focus on the actual question parts.

19: The part in the parenthesis is a quotient because it is the solution to the division.

20: 5.3t is a product of 2 factors because you are multipliying 5.3 times t

I hope this helps. :)

In ΔOPQ, the measure of ∠Q=90°, OQ = 80, QP = 39, and PO = 89. What ratio represents the cosecant of ∠P?
Serjik [45]

Answer:

cos(O) = 39 / 89

Step-by-step explanation:

Given:

ΔOPQ, where

∠Q=90°

PO = 89

OQ = 39

QP = 80

cosine of ∠O?

cos(O) = Adjacent / Hypotenuse

cos(O) = 39 / 89

EASY MATH QUESTIONS<br><br> NEED HELP
Nikitich [7]

Answer:

f(6) = -14

Step-by-step explanation:

x = -6

f(x) = x^2/3 - 2

f(-6) = (-6)^2/3 -2         Replace x with the given number

      = -36/3 - 2            Simplify -6 to the power of 2

      = - 12 - 2                Divide -36 by 3

f(6) = - 14                      Subtract -2 from -12

BRAINLIEST TO CORRECT
Masteriza [31]

Answer:

Step-by-step explanation:

So we know they had got $22,553 which is 90% more than last year. With this information we know:

190% = $22,553

1% = $22,553/190

1% = $118.70

100% = $11870

So overall it would be $11870 which they had got last year

A line passes through the point (8,9) and has a slope of 3/4
stepan [7]

Answer: y=\frac{3}{4}x+3

Step-by-step explanation:

Slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept. Since we are given slope, we can plug that into m, and use the given point to find the y-intercept.

y=\frac{3}{4}x+b          [plug in (8,9)]

9=\frac{3}{4}(8)+b       [multiply]

9=6+b            [subtract both sides by 6]

b=3

Now that we have b, we can complete the equation to y=\frac{3}{4}x+3.
