Answer:
32.85°
Step-by-step explanation:
Used a fancy calculator & just took a test like this
good luck, i hope this helps :)
Answer:
x = 32.8599
Step-by-step explanation:
you have the hypotenuse and the side adjacent to the angle, so you use
Cos(x) = adjacent/hypotenuse
so
Cos(x) = 21/25
x = cos^-1(21/25)
put this in a calculator:
x = 32.8599 (rounded)

Answer:
LN = 4.326
Step-by-step explanation:
dropping a perpendicular from point k to LM
call that point on line LM, point X
angle KLM = 47 degrees so angle NKL = 28 degrees
sin 47 = KX/8.9
KX = 6.509
angle LKX = 90-47-28 = 15 degrees
tan 15 = XN/6.509
XN = 1.744
cos 47 = XL/8.9
XL = 6.070
XL-XN=LN
LN = 6.070-1.744 = 4.326
how would I do this?

Jennifer has one more nickel than she has dimes. If she has $1.25 how many of each type of coin does she have? (HELP IS APPRECIATED)
Answer:
She has 9 nickels, and 8 dimes.
Step-by-step explanation:
We know that she has a total of $1.25. We know that a nickel is $0.05, and that a dime is $0.10.
9x$0.05=$0.45
8x$0.10=$0.80
Answer:
9 nickels
8 dimes
Step-by-step explanation:
.05(n + 1) + .10n = 1.25
.05n + .05 + .10n = 1.25
.15n = 1.20
n = 1.2 / .15
n = 8
but there are 9 nickels because there is "one more nickel than dimes"
Solve the equation n/10 + 5 =9. The solution is (Type the value of n.)
Answer:
40
Step-by-step explanation:
n/10+5=9
n/10=9-5
n/10=4
n=4*10
n=40

Answer:
x=16[tex]\sqrt{\\2\\}[/tex]
y= 16
Step-by-step explanation:
Since we know that this is a right triangle, all sides must add up to 180°. This means that our unknown angle is 45°. With two 45° angles, we know that side y must be 16 (the same as the other corresponding angle). Once we know both legs, we can use Pythagorean Theorem to determine that the hypotenuse, or side x is =16[tex]\sqrt{2}[/tex]
f(x)=4x^2 − 10x+2
Find f(−7)
Answer:
f(-7)=268
Step-by-step explanation:
f(-7)=4x^2 − 10x+2
f(-7)=4(-7)^2-10(-7)+2
f(-7)=4(49)+70+2
f(-7)=196+72
f(-7)=268
Answer:
198
Step-by-step explanation:
4(-7)^2+70+2
196+2=198

There are many cylinders with a height of 9 inches. Let R represent the radius in inches and V represent the volume in cubic inches.
R V
1

3
Complete the table relating the radius and volume of cylinders with height 9 inches. Write each volume as a multiple of pi or round to the nearest cubic inch.
Is there a linear relationship between the radius and the volume of these cylinders? Explain how you know.
If a cylinder with height 9 inches and radius (R) s filled with water, it can fill a certain pitcher. How many of these pitchers can a cylinder with height 9 inches and radius 2r fill? Explain how you know.
Answer:
R V
1 9π in³
2 36π in³
3 81π in³
Step-by-step explanation:
For, r = 1
V = π(1)²9 = 9π in³
For, r = 2
V = π(2)²9 = 4*9π in³ = 36π in³
For r = 3
V = π(3)²9 = 9*9π in³ = 81π in
R V
1 9π in³
2 36π in³
3 81π in³

using the graph as your guide
Answer:
C
Step-by-step explanation:
The discriminant informs us about the nature of the zeros
• If b² - 4ac > 0 then 2 real and distinct zeros
• If b² - 4ac = 0 the 2 real and equal zeros
• If b² - 4ac < 0 then zeros are not real
The graph crosses the x- axis at 2 distinct zeros, then
b² - 4ac > 0 , that is positive → C
I don’t know if it’s true or false
