If triangle ABC has the followingmeasurements, find the measure of side c.
a = 10
b = 3
C = 15°
(Hint: c^2 = a^2 +b^2 - 2ab*cos(C) is law of
cosine)

Answers

Answer 1
Answer:

Answer:

Measure of side C is 7.14

Step-by-step explanation:

In this question, we are to find the length of the side C.

To get this, we are to employ the use of the cosine formula.

Mathematically, this is calculated as;

c^2 = a^2 +b^2 - 2ab*cos(C)

Where; a = 10 b = 3 and c = 15 degrees

Plugging these values into the equation, we have;

C^2 = 10^3 + 3^2 -2(3)(10)Cos 15

C^2 = 100 + 9 - 57.96

C^2 = 51.04

C = √(51.04)

C = 7.14

Chen spins the spinner and rolls a standard number cube. Find the probability that’s the spinner will stop on blue and the cube will show four. Write the probability as a fraction in simplest form. (Spinner shows 4 quarters, all different colors. Yellow, orange, red and blue.)

Answers

Answer: 1/24

Step-by-step explanation:

You multiply the fraction of the first probability by the fraction of the second probability.

The spinner has 4 colors, the odds of it landing on blue is 1/4

The cube has 6 numbers, the odds of it landing on 4 is 1/6

1/4 * 1/6 = 1/24

Logan saves the same amount of money each month for college. His current total savings is 300m2 + 120m + 180 dollars. Which factorization could represent the number of months and amount of a monthly deposit in dollars?

Answers

If we let x as the amount of money saved per month and m be the number of months:

xm = 300m2 + 120m 180

The quadractic equation would result to:
300m2 + (120-x)m + 180 = 0

Using the quadratic formula we have the following factorization:
(m - ( -120 + x + sqrt (x2 - 240x - 2145600) ) / 600) (m - ( -120 +x - sqrt (x2 - 240x - 2145600) ) / 600) = 0

60(5m2 +2m +3)                               the answer is d

PLEASE HELP Solve |4x - 7| = 13.

Answers

 the absolut value signs mean that whatever is inside of them, you make it positive.  so 4x-7 could equal 13 or -13 or both

so 4x-7=13
add 7 to both sides
4x=20
divide both sides by 4
x=5
this is one solution

4x-7=-13
add 7 to both sides
4x=-6
divide both sides by 4
x=-1.5

x=5 or -1.5
|4x - 7| = 13\n4x-7=13 \vee 4x-7=-13\n4x=20 \vee 4x=-6\nx=5 \vee x=-(6)/(4)=-(3)/(2)

What is the quotient of b^3+4b^2-3b+126/b+7A. b² + 11b + 80 R276
B. b² − 3b + 18 (Wrong)
C. b² − 11b + 38 R140
D. b² − 3b + 18 R252

Answers

The correct answer for the question that is being presented above is this one: "D. b² − 3b + 18 R252. The quotient of b^3+4b^2-3b+126/b+7. In order to get the answer, you have to start dividing b^3 by b. Then multiply the quotient to b + 7. Then after that, subtract. Do the same thing until you reached the end.
