Answer:
77/85
Step-by-step explanation:
Given:
cos(A) = 4/5
sin(B) = 15/17
Find:
cos(A-B)
Solution:
From your knowledge of Pythagorean triples, you know that one of them is (3, 4, 5) and another is (8, 15, 17). Using your imagination, or by drawing the triangles, you can determine the needed trig functions to be ...
sin(A) = 3/5
cos(B) = 8/17
__
Alternatively, you can use the Pythagorean identity to find ...
sin(A) = √(1 -cos²(A)) = √(1 -(4/5)²) = √(9/25) = 3/5
cos(B) = √(1 -sin²(B)) = √(1 -(15/17)²) = √(64/289) = 8/17
__
Then application of the angle difference formula is straightforward.
cos(A -B) = cos(A)cos(B) +sin(A)sin(B)
cos(A -B) = (4/5)(8/17) +(3/5)(15/17) = (32 +45)/85
cos(A -B) = 77/85
_____
Some graphing calculators can express the result ...
cos(arccos(4/5) -arcsin(15/17)) ≈ 0.90588235294
... as the fraction 77/85

Jay bought a guitar on sale at 45% off. The original price was $576.75.
(a)
Find the amount of discount. (Round your answer to the nearest cent.)
$
(b)
Find the sale price. (Round your answer to the nearest cent)
Answer:
317.21 (sales price)
259.53 (discount amount)
Step-by-step explanation:
First, we need to divide.
576.75/100=5.7675 (note that I will be rounding at the end)
5.7675 x 55 (100-45) = 317.2125
Rounds to: 317.21
Now, we need to find the discount amount.
576.75
-317.21
=259.53

F(x)= x^2+7x+10/ x^2 - 7x+6
A. 8.333
B. 6.333
C. 7.666
D. 6.667
Answer:
add all the numbers and divide by 4
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
F(0)= 0^2+7(0)+10/ 0^2 - 7(0)+6 = 1.67
F(0.5)= 0.5^2+7(0.5)+10/ 0.5^2 - 7(0.5)+6 = 5
[tex]RateofChange = \frac{F(0.5) - F(0)}{0.5 - 0} = 6.667[/tex]
According to Masterfoods, the company that manufactures M&M's, 12% of peanut M&M's are brown, 15% are
yellow, 12% are red, 23% are blue, 23% are orange and 15% are green. [Round your answers to three decimal
places, for example: 0.123]
Compute the probability that a randomly selected peanut M&M is not brown.
Compute the probability that a randomly selected peanut M&M is brown or orange.
Compute the probability that three randomly selected peanut M&M's are all yellow.
If you randomly select six peanut M&M's, compute that probability that none of them are brown.
If you randomly select six peanut M&M's, compute that probability that at least one of them is brown.
Answer(In bold)/Step-by-step explanation:
Compute the probability that a randomly selected peanut M&M is not blue
P (blue) = 23%
P (blue)C = 1 - P(blue) = 100% - 23% = 77%
Compute the probability that a randomly selected peanut M&M is green or red.
P (green) = 15%
P (red) = 12%
P (green or red) = P(green) + P(red) = 27%
Compute the probability that three randomly selected peanut M&M’s are all yellow.
P (yellow) = 15%
(P(yellow))3 = 0.338%
There was replacement in the selection process.
If you randomly select six peanut M&M’s, compute that probability that none of them are brown.
P(brown) = 12%
P(brown)C = 1 - P(brown) = 100% - 12% = 88%
(P(brown)C)6 = 46.440%
1. Becky needs to earn an average of 85% on her Stats tests in order to maintain her current GPA. IF
she has gotten the following scores so far, what does she need to get on her next test to maintain at
least an 85% average?
85, 78, 92, 84, 93
Answer:
78%
Step-by-step explanation:
85 × 6 = 510
85 + 78 + 92 + 84 + 93 = 432
510 - 432 = 78
Check
85 + 78 + 92 + 84 + 93 + 78 = 510
510 ÷ 6 = 85

Answer: 30°
Step-by-step explanation:
we have to find the angle adjacent with the right angle. For this we use the (-).
At this point, I am guessing you know how to use SOH-CAH-TOA, for this one we use SOH so sin. If you have a calculator set it on degree mode, then plug it in as sin⁻₁(), we put it like that because the missing angle has the given number opposite and the hypotenuse. It solves it and now we get 30 for the answer. I dont know if that made sense, tell me if it didnt so I can explain it better.
