Answer:
64(ab÷c²)
step by step:
(when you multiply two similar bases you can add their exponents but when dividing similar bases you subtract their exponents)
for example
a³x a= a⁴
a²÷ a= a²-¹= a
so
4a³x 16a⁰b¹÷ 1ac²=
64a³b÷ac²
64a²b/c²
Coach Brown buys packs of Gummi Bears at $0. 60 and resales them at $1. 0. At what percent did he mark the candy up?
A. 10. 47
B. 3. 59
C. 9
D. 67
E. 69
F. 10. 25
If the coach buys the packs of Gummi Bears at $0.60 and resales them at $1 , then the percent markup for the candy is (d) 67% .
The price for which the Coach buys Gummi Bears is = $0.60 ;
the price at which the Coach resales them is = $1 ;
So , the Markup is the difference in the price of purchase and price of resale of the candy ,
that means ; the [tex]Markup = \$1 - \$0.60[/tex] ;
= $0.4
So , the Percent Markup is = [tex]\frac{0.4}{0.6} \times 100[/tex]
= 66.66666...
≈ 67% .
Therefore , the percent Markup for the Candy is 67% .

One of the legs of a right triangle measures 14cm and its hypotenuse measures 15cm. Find the measure of the other leg
the measure of the missing leg is 5.38
or 5.4
Step-by-step explanation:
s is for Squared
Cs= As+Bs
let's say 14cm was side a
Bs=Cs-As
Bs= 15s-14s
Bs=225-196
Bs=29
B= square root of Bs
B=5.38
Answer:
5.4
Step-by-step explanation:
c² = a² + b²
15² = 14² + b
225 = 196 + b
b = 225 - 196
= 29
= 5.4

Step-by-step explanation:
Show that f is continuous on (−[infinity], [infinity]). f(x) = 1 − x2 if x ≤ 1 ln(x) if x > 1
On the interval
(−[infinity], 1),
f is function; therefore f is continuous on
(−[infinity], 1).
On the interval
(1, [infinity]),
f is function; therefore f is continuous on
(1, [infinity]).
The function [tex]$$f(x)= \begin{cases}1-x^2 & x \leqslant 1 \\ \ln (x) & x \geqslant 1\end{cases}$$[/tex] is continuous on (-∞, ∞).
As per the given data the function f(x) is given by:
[tex]$$f(x)= \begin{cases}1-x^2 & x \leqslant 1 \\ \ln (x) & x \geqslant 1\end{cases}$$[/tex]
Here we have to determine that the function f(x) is continuous on (-∞, ∞)
If we show that f(x) is continuous at x = 1 then f(x) is continuous on (-∞, ∞)
What are continuous function?
A continuous function in mathematics is one where changes in the parameter cause constant changes in the function's value (i.e., a change without a leap). This shows that there are no abrupt changes in value or discontinuities.
To show f(x) is continuous at x = 1
[tex]\lim _{x \rightarrow 1^{-}} f(x)=\lim _{x \rightarrow 1^{+}}[/tex] f(x)
[tex]\rightarrow \lim _{x \rightarrow 1^{-}} f(x) & =\lim _{x \rightarrow 1^{-}}\left(1-x^2\right) \\[/tex]
= 1 - 1
= 0
[tex]\lim _{x \rightarrow 1^{+}} f(x) & =\lim _{x \rightarrow 1^{+}} \ln (x) \\[/tex]
= ln 1
= 0
Therefore [tex]\lim _{x \rightarrow 1^{+}} f(x) & =\lim _{x \rightarrow 1^{-}} f(x)-0[/tex].
Hence f(x) is continuous on (-∞, ∞)

Answer:
1) x²=256-64
x=8√3
2). x²=200+81
x=√281
3). x²=169+36
x=√205
3).
Step-by-step explanation:
here's your solution
==> in figure 1,
= perpendicular^2 = hypotenuse^2 - base^2
= x^2 = 16^2 - 8^2
= x^2 = 256 - 64
= x^2 = 192
= x = √192
= x = 13.85
==> in figure 2,
= hypotenuse^2 = Perpendicular^2 + base^2
= x^2 = 40^2 + 9^2
= x^2 = 1600 + 81
= x^2 = 1681
= x = √1681
= x = 41
==> in figure 3,
= hypotenuse^2 = Perpendicular^2 + base^2
= x^2 = 13^2 + 6^2
= x^2 = 169 + 36
= x^2 = 205
= x = √205
= x = 14.31

PLS WHAT IS THE VALUE OF X SOMEONE
Answer:
It would be 166 degrees.
Step-by-step explanation:
Do 180-97 to get 83 degrees
Since the triangle is a isosceles triangle, the opposite side of it would also be 83 degrees, so 83+83
With this, do 180-83-83 to get 14 degrees for the third interior angle
Last, subtract this from 180 to get the value of x, 166 degrees.

On solving the provided question, we can say that the sequence what we tell on day 3 = he sold 5; on day 4 = he sold 7; on day 5 = he sold 9
what is a sequence?A collection of numbers, or "terms," is referred to as a sequence. Examples of terms are 2, 5, and 8. Some sequences can be made endlessly lengthy by taking advantage of a particular pattern they follow. Use the example of 2,5,8 and add 3 to continue the sequence. There are formulas that demonstrate where to look for words within a sequence. A collection of objects that are in some order is known as a sequence in mathematics (or events). It resembles a set in that it contains pieces (also called elements or terms). The entire, perhaps infinite number of ordered objects are referred to as the sequence's length. the act of placing two or more items in a logical order. Chronological.

on day 1 = he sold 1
on day 2 = he sold 3
on day 3 = he sold 5

Which of these characteristics of a star make it most likely to become a black hole? Select the TWO!!!! correct answers.
A. Its mass is equal to that of the sun.
B. It has an abundant supply of hydrogen.
C. Its mass is greater than 20 times the mass of the sun.
D. It is dying.
Answer and Step-by-step explanation:
C and D is the answer.
It needs a lot of mass so that it can collapse on itself to form a black hole, and when it dies, it also collapses on itself, forming a black hole.
A is incorrect because the mass of our sun hasn't made it to collapse, and it still has some billions of years before the mass increases.
B is incorrect because the hydrogen needs to be depleted in order for the sun/star to start the nuclear process.

Answer:
1.) The 1ˢᵗ three term is (-32), (-7) and 18
2.) The 1ˢᵗ three term is 127, 106 and 85
Step-by-step explanation:
1.)Here,
First Term = a₁ = - 32
Common Difference = (d) = 25
Now, For 1ˢᵗ three term,
n = 1
a₁ = - 32
n = 2
aₙ = a + (n - 1)d
a₂ = (-32) + (2 - 1) × 25
a₂ = (-32) + 1 × 25
a₂ = (-32) + 25
a₂ = -7
n = 3
aₙ = a + (n - 1)d
a₃ = (-32) + (3 - 1) × 25
a₃ = (-32) + 2 × 25
a₃ = (-32) + 50
a₃ = 18
Thus, The 1ˢᵗ three term is (-32), (-7) and 18
2.)Here,
First Term = a₁ = 127
Common Difference = (d) = -21
Now, For 1ˢᵗ three term,
n = 1
a₁ = 127
n = 2
aₙ = a + (n - 1)d
a₂ = 127 + (2 - 1) × (-21)
a₂ = 127 + 1 × (-21)
a₂ = 127 - 21
a₂ = 106
n = 3
aₙ = a + (n - 1)d
a₃ = 127 + (3 - 1) × (-21)
a₃ = 127 + 2 × (-21)
a₃ = 127 - 42
a₃ = 85
Thus, The 1ˢᵗ three term is 127, 106 and 85

The population of the city grew from 2010 to 2020 by 13.37 %
What is percentage?A percentage is a number that tells us how much out of 100 and can also be written as a decimal or a fraction.
Given that, In 2010, the population of a city was 237,000. From 2010 to 2015, the population grew by 7.6%. From 2015 to 2020, it fell by 4.7%.
The population in 2015 =
A = P (1+r)ⁿ
A = final population.
P = Initial population.
r = rate
n = time
The population in 2015 =
A = 237,000(1+0.076)⁵
A = 341829.629
The population in 2020 =
A = P (1-r)ⁿ
A = 341829.629(1-0.047)⁵
A = 268704.047
Percent grow = 268704.047 - 237,000 / 237,000 × 100
= 31704.047 / 237,000 × 100
= 13.37 %
Hence, the population of the city grew from 2010 to 2020 by 13.37 %

URGENT!! 50 POINTS!!! based on the linear table of ordered pairs, what is the y intercept?
Answer:
y- intercept = 0
Step-by-step explanation:
the linear function can be expressed in slope- intercept form, that is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁ , y₁ ) = (4, - 4) and (x₂, y₂ ) = (- 2, 2) ← 2 ordered pairs from the table
m = [tex]\frac{2-(-4)}{-2-4}[/tex] = [tex]\frac{2+4}{-6}[/tex] = [tex]\frac{6}{-6}[/tex] = - 1
the line crosses the y- axis at (0, 0 ) ⇒ c = 0
y = - x + 0, that is
y = - x ← is the linear function defining the ordered pairs in the table
if cosØ=1/6 what are the values of sinØ and tanØ?
Answer:
Step-by-step explanation:
cos theta = (adjacent side) / (hypotenuse) = 1/6. The adjacent side has length 1 and the hypotenuse length 6. The opposite side has length
√(6^2 - 1^2) = ÷√35
and so sin theta = (opp side) / (hypotenuse) = (√35) / 6
and tan theta = [(√35) / 6] / (1/6), or √35
