What is the value of this expression when c=-4 and d = 10?
1/4(c3+d2)
What is the value of this expression when c = -4 and d = 10 ? [tex] \frac{1}{4} [/tex] (c³ + d²)
Answer:-Given:-[tex] \frac{1}{4} [/tex] (c³ + d²) where c = -4 and d = 10
To Find:-The value of the expression [tex] \frac{1}{4} [/tex] (c³ + d²)
Solution:-[tex] \frac{1}{4} [/tex] (c³ + d²) [Given expression]
Now, putting the value of c = -4 and d = 10 , we get,
[tex] \frac{1}{4} [/tex] { (-4)³ + (10)² }
[tex] \frac{1}{4} [/tex] ( -64 + 100 )
[tex] \frac{1}{4} [/tex] ( 36 )

Line x and line z are straight lines.
Which pair of angles are vertical?
O Za and Zd
Zb and Zd
Za and ZD
O Zc and Ze
Mark this and return
Answer:
[tex]\angle c[/tex] and [tex]\angle e[/tex]
Step-by-step explanation:
Given
See attachment
Required
Identify the vertical angles
Keynotes
Vertical angles opposite one anotherVertical angles are equal to one anotherUsing the keynote as a reference, we have the following observation from the attachment:
[tex]\angle c[/tex] and [tex]\angle e[/tex] are opposite
[tex]\angle c[/tex] and [tex]\angle e[/tex] are congruent
Hence:
[tex]\angle c[/tex] and [tex]\angle e[/tex] are vertical

whats the surface area of 12 length 4 high and 5 width it is also a Triangle prism
Answer:
The answer is most likely 174.68
Step-by-step explanation:
Using the formula A = (2A_B) + (a + b + c)(h)
we can find the surface area
12 is a and c
5 is b
4 is h
This question was vague so the answer might be incorrect.
A box is shaped like an octagonal prism. Here is what the base of the prism looks like. If the height of the box is 7 inches, the volume of the box will be [1] cubic inches.
Answer:
The volume of the box is 33.796 cubic inches
Step-by-step explanation:
Given
[tex]Height = 7in[/tex]
See attachment for the base of the prism
Required
The volume of the box
From the attachment, we have:
[tex]a = 1in[/tex] -- side length of the octagon
The area is then calculated as:
[tex]Area = 2 * (1 + \sqrt 2)a^2[/tex]
So, we have:
[tex]Area = 2 * (1 + \sqrt 2)* 1^2[/tex]
[tex]Area = 2 * (1 + \sqrt 2)* 1[/tex]
[tex]Area = 2 * (1 + \sqrt 2)[/tex]
Evaluate the square root
[tex]Area = 2 * (1 + 1.414)[/tex]
[tex]Area = 2 * (2.414)[/tex]
[tex]Area = 4.828[/tex]
The volume is then calculated as:
[tex]Volume = Height * Base\ Area[/tex]
[tex]Volume = 7 * 4.828[/tex]
[tex]Volume = 33.796[/tex]

Answer:
a) [tex]p = 88\,cm[/tex], b) [tex]p = 24\,cm[/tex], c) [tex]p \approx 25.424\,m[/tex], d) [tex]p \approx 39.368\,cm[/tex]
Step-by-step explanation:
a) The perimeter is the sum of the three sides of the internal square and the remaining sides of the external rectangle, that is:
[tex]p = 3\times 8\,cm + 2\times 4\,cm +2\times 20\,cm + 16\,cm[/tex]
[tex]p = 88\,cm[/tex]
b) The perimeter is the sum of the two sides of the internal triangle and the remaining sides of the external rectangle, that is:
[tex]p = 2\times 4\,cm + 2\times 6\,cm + 4\,cm[/tex]
[tex]p = 24\,cm[/tex]
c) The perimeter is the sum of the two sides of the circular section and the three sides of the lower rectangle, that is:
[tex]p = \frac{\pi}{2}\times 6\,cm + 8\,cm + 6\,cm + 2\,cm[/tex]
[tex]p \approx 25.424\,m[/tex]
d) The perimeter is the sum of the external sides of the triangle and rectangle, that is:
[tex]p = 10\,cm + 12\,cm + 12\,cm + 12\,cm - \sqrt{(12\,cm)^{2}-(10\,cm)^{2}}[/tex]
[tex]p \approx 39.368\,cm[/tex]

Answer:
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] × [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
There is a common ratio r between consecutive terms
r = [tex]\frac{384}{512}[/tex] = [tex]\frac{288}{384}[/tex] = [tex]\frac{216}{288}[/tex] = [tex]\frac{3}{4}[/tex] , then recursive formula is
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] × [tex]\frac{3}{4}[/tex] : a₁ = 512

What is the percentage of decrease from 2 to 1
Using a random sample of 4100 households, a media research company finds that 55.1% watched a particular episode of a popular situation comedy. a. Find the margin of error in this percent. b. Write a statement about the percentage of TV households in the population who watched the episode of the situation comedy.
Answer:
a. 1.52%
b. There is 95% probability that the true population percentage lies between 53.8$ and 56.62%
Step-by-step explanation:
The number of participants in the sample, n = 4,100
The percentage that watched the particular popular situation episode, p = 55.1%
a. The margin of error is given by the following formula;
[tex]Margin \ of \ Error = Z_{\alpha /2} \times \sqrt{\dfrac{p \times (1 - p)}{n} }[/tex]
Where;
Z = The z-score at 95% = 1.96
p = The proportion of the sample that responded positively = 55.1% = 0.551
n = 4,100
From the above data, we get;
[tex]Margin \ of \ Error = 1.96 \times \sqrt{\dfrac{0.551 \times (1 - 0.551)}{4,100} } \approx 0.0152252[/tex]
The margin of Error ≈ 1.52%
b. The confidence interval is give as follows;
[tex]p \pm Z_{\alpha /2} \times \sqrt{\dfrac{p \times (1 - p)}{n} }[/tex]
Therefore, we get the 95% confidence interval as follows'
55.1 - 1.52 ≤ μ ≤ 55.1 + 1.52
53.8% ≤ μ ≤ 56.62%
The answer as formatted in an online source is presented as follows;
There is 95% probability that the true population percentage lies between 53.8$ and 56.62%.

What is the measure of angle 4?
angles 1,3,5,6,7, and 8 are 73 degrees. angles 2 is 107 degrees
Answer:
34 Deg
Step-by-step explanation:
Since the Triangle is isoceles, each of the internal base angle = 180-107=73
Sum of internal angles =180, Angle4= 180-(73+73)= 180-146=34
a skateboard is on sale for $47.80. if this price represents a 50% discount from the original price, to the nearest cent?
Answer:
95.60$
Step-by-step explanation:
50% discount is basically the price divided by 2. So if we inverse it it will become x2. 47.80x2=95.6

An electronics store buys 200 stylus at a cost of $400 and sells them for $6 each. Find the percent markup rounded to the nearest percent?
Answer:
Percent markup is 200%
Step-by-step explanation:
The cost of each stylus is
[tex]\frac{400}{200} = 2[/tex] dollars
The selling price of each stylus is $6
Percent markup =
(Selling price - cost price)/cost price *100
[tex]\frac{6-2}{2} *100\\2*100\\200[/tex]%
Percent markup is 200%

if the two points are (9, 260) and (29.5, 530), calculate the slope of the line that runs through them.
A. 13.17
B. 12.25
C. 11.32
D. 10.42
Answer:
m = rise/run = 270/20.5 = 13.17
Step-by-step explanation:
Going from (9, 260) to (29.5, 530), we see that the horizontal change (in x) is 20.5 and the vertical change (in y) is 270. Thus, the slope is
m = rise/run = 270/20.5 = 13.17
