The percent of the pencils in the pack are black is,
⇒ 80%
And, The fraction of the pencils in the pack is black is,
⇒ 24 / 30
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
Ms. Cathy bought a package of pencils.
And, Out of every 10 pencils, 8 are black. .
Since, There are 30 pencils in the pack,
Hence, The percent of the pencils in the pack are black is,
⇒ 24 / 30 x 100
⇒ 2400 / 30
⇒ 80%
And, The fraction of the pencils in the pack is black is,
⇒ 8 / 10 = x / 30
⇒ 240 = 10x
⇒ x = 24
Thus, The fraction of the pencils in the pack is black is,
⇒ 24 / 30
Thus, The percent of the pencils in the pack are black is,
⇒ 80%
And, The fraction of the pencils in the pack is black is,
⇒ 24 / 30

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

Select all the correct answers. Exponential function f is represented by the table. x 0 1 2 3 4 f(x) -12 -4 0 2 3 Function g is represented by the equation. g(x)=-12(1/3)^x Which statements are true about the two functions? Both functions are increasing on all intervals of x. The functions have the same y-intercept. Both functions approach the same value as x approaches ∞. Both functions approach -∞ as x approaches -∞. The functions have the same x-intercept.
Answer:
Both functions are increasing on all intervals of x: True
Both functions have the same y intercept: True
Both functions approach the same value as x approaches infinity: True
Both functions approach negative infinity as x approaches negative infinity: True.
The functions have the same x intercept: False, they have no x intercept.
Step-by-step explanation:
f(x) is stated to be an exponetial function, hence
[tex]f(x)=ab^{x}[/tex]
f(0) is given as -12, so
-12=a
f(1) is given as -4, so
-4=-12b
b=1/3
This implies that
[tex]f(x)=-12(\frac{1}{3})^{x}[/tex]
g(x) is stated to be
[tex]g(x)=-12(\frac{1}{3})^{x}[/tex]
Conclusion: the functions are identical.
Answer:
so the answers are
the functions have the same y-intercept
both functions approach negative infinity as x approaches infinity
both functions are increasing on all intervals of x

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
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

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)

Identify the correct table for the following equation: Y=3x + 7 ( look at the picture for answer choices )
Answer:
The first choice is the right answer.
Step-by-step explanation:
Y = 3x+7
First choice
y = 3(0) + 7 = 7
y = 3(1) + 7 = 10
y = 3(2) + 7 = 13
second choice
y = 3(7) + 7 = 28. output on table shows 0
third choice
y = 3(0) + 7 = 7
y = 3(1) + 7 = 10 doesn't work as y output in third choice says 8
fourth choice.
y = 3(7) + 7 = 28 output on table shows 0
1/10 (x + 11) = -2 (8 - x)
Answer: (5/8)x
