Answer:
answer is 27 degrees
Step-by-step explanation:
first of all complementary angles add up to 90 degrees and you were given one angle
63 + x = 90
63-63 +x =90 -63
x = 27
hope that helps
help please due soon
Answer:
y = 6x
Step-by-step explanation:
You can easily find the slope by using slope formula:
(y2-y1) / (x2-x1) (the numbers are subscript)
E.g: (24-12) / (4-2) = 12/2 = 6
m(slope) = 6
Hope this helped :)

Step-by-step explanation:
For this exponential function what is the output value (y) when the input value (c) is 3?
Answer:
y = 40
Step-by-step explanation:
Given, y = 5 * 2^x
If x = 3, y would be:
Substitute the value of x into the given function.
Thus,
y = 5*2³
y = 5*8
y = 40

A mistake was made in the steps shown to simplify the expression. Which step includes the mistake?
9/2+ 3(4 – 1) – 7 + 23
Step 1: = 9/2+ 3(3) — 7 + 23
Step 2: = 9/2 + 3(3) - 7 + 8
Step 3: =15/2 (3) — 7+8
Step 4: =45/2 - 7+8

Answer:
multiplication property of equality. Hope this help and maybe a brainlist?
Step-by-step explanation:
Answer:
multiplication property of equality
Step-by-step explanation:
d/10=12
Multiply both sides by the equation by 10
10× d/10=10×12
Reduce the numbers by the greatest common factor which is 10
d=10×12
Multiply 10 and 12
d=120
So using multiplication to solve this equation
Use the Distributive Property to expand the following expressions.
a.) 2 ( y + 5x) = _______________
b.) 0.4 ( x + 2) = ______________
Answer:
Step-by-step explanation:
Distributive property: a(b +c)=(a*b )+(a*c)
a) 2(y + 5x) = y*2 + 5x*2
= 2y + 10x
b) 0.4(x + 2) = x*0.4 + 2*0.4
= 0.4x + 0.8

⦣G and ⦣H are complementary. If the measure of ⦣H is 72°, what is the measure of ⦣G?
9514 1404 393
Answer:
∠G = 18°
Step-by-step explanation:
Complementary angles total 90°. The measure of G is ...
∠G = 90° -72° = 18°

Answer:
1. x = 65
2. x = 40
3. x = -7
4. x = -4
5. x = -7
6. x = 4
Step-by-step explanation:
Angles in a triangle always add up to 180 degrees.
Thus, for each triangle you can write an equation setting the sum of the three angles equal to 180, and solving for x.
1. 180 = 80 + 35 + x
180 - (80 + 35) = x
180 - 115 = x
65 = x
2. 180 = 70 + 70 + x
180 - (70 + 70) = x
180 - 140 = x
40 = x
3. 180 = 76 + 41 + (x+ 70)
180 - (76 + 41) = x + 70
180 - 117 = x + 70
63 = x + 70
63 - 70 = x
-7 = x
4. (the red square means its a right angle = 90 degrees)
180 = 90 + 25 + (x + 69)
180 - (90 + 25) = x + 69
180 - 115 = x + 69
65 = x + 69
65 - 69 = x
x = -4
5. 180 = 50 + (57 +x) + (x + 87)
180 - 50 = (57 +x) + (x + 87)
130 = (57 +x) + (x + 87)
combine like terms
130 = 144 + 2x
130 - 144 = 2x
-14 = 2x
-7 = x
6. 180 = 80 + (9x + 4) + (16x - 4)
180 - 80 = (9x + 4) + (16x - 4)
100 = (9x + 4) + (16x - 4)
combine like terms
100 = 25x + 0
100 = 25x
4 = x

[tex]\frac{2}{x}[/tex]=[tex]\frac{12}{15}[/tex]
Cross multiply
12x=30
Divide
x=2.5
This is just one way to do the problem. An easier way is to simplify the fractions.
[tex]\frac{2}{x}[/tex]=[tex]\frac{4}{5}[/tex]
You can either cross multiply or figure out that 2 is half of four and simply divide 5 by 2 which will also result in 2.5

Find the 80th derivative of f(c)
ET
sin(2).
f(80)
Submit Question
Compute the first few derivatives to reveal a pattern:
f(x) = x sin(x)
f '(x) = x cos(x) + sin(x)
f ''(x) = (-x sin(x) + cos(x)) + cos(x) = -x sin(x) + 2 cos(x)
f '''(x) = (-x cos(x) - sin(x)) - 2 sin(x) = -x cos(x) - 3 sin(x)
f ''''(x) = (x sin(x) - cos(x)) - 3 cos(x)) = x sin(x) - 4 cos(x)
f ⁽⁵⁾(x) = (x cos(x) + sin(x)) + 4 sin(x) = x cos(x) + 5 sin(x)
f ⁽⁶⁾(x) = (-x sin(x) + cos(x)) + 5 cos(x) = -x sin(x) + 6 cos(x)
f ⁽⁷⁾(x) = (-x cos(x) - sin(x)) - 6 sin(x) = -x cos(x) - 7 sin(x)
f ⁽⁸⁾(x) = (x sin(x) - cos(x)) - 7 cos(x) = x sin(x) - 8 cos(x)
and so on.
The pattern should be clear: for some integer k,
• if n = 4k, then f ⁽ⁿ ⁾(x) = x sin(x) - n cos(x)
• if n = 4k + 1, then f ⁽ⁿ ⁾(x) = x cos(x) + n sin(x)
• if n = 4k + 2, then f ⁽ⁿ ⁾(x) = -x sin(x) + n cos(x)
• if n = 4k + 3, then f ⁽ⁿ ⁾(x) = -x cos(x) - n cos(x)
80 is a multiple of 4, so the 80th derivative falls in the first category. Then
f ⁽⁸⁰⁾(x) = x sin(x) - 80 cos(x)
