WHen f(x) = f(5)
x=5
therefore y = 5
Hope that helped!!! k
Answer:
5
Step-by-step explanation:
Asking for f(5) is the same as asking for the value of f(x) when x = 5.
So we're looking for the y-value our graph gives when x = 5.
Find 5 on the x-axis and trace the line up to the graph, and then left to find the y-value. Here, it happens to be 5.

The four angles in a quadrilateral are in the ratio 2:5:6:7. Find the smallest angle in the quadrilateral?
Answer:
36
Step-by-step explanation:
Quadrilateral's angels always add up to 360. Thus, 2x+5x+6x+7x=360
20x=360 (divide both sides by 20)
x = 18
To find the smallest angle, plugin x into 2x.
2(18)=36

Pleaseeee solve this math for me I reallyyyy neeed help
Pleaseee
Any wrong answer I’ll report
Answer:
see explanation
Step-by-step explanation:
Given that z² is directly proportional to w then the equation relating them is
z² = kw ← k is the constant of proportion
To find k use the condition z = 4 when w = 8, thus
4² = 8k
16 = 8k ( divide both sides by 8 )
2 = k
(i)
z² = 2w ← equation of proportion
(ii)
When w = 18, then
z² = 2 × 18 = 36 ( take the square root of both sides )
z = [tex]\sqrt{36}[/tex] = 6
(iii)
When z = 5 , then
5² = 2w
25 = 2w ( divide both sides by 2 )
w = 12.5

Hello, I assume that the quadratic function f has real coefficients, so this is something like, a, b and c being real numbers
[tex]f(x)=ax^2+bx+c[/tex]
If a complex number z is a zero of f ( meaning solution of f(x)=0) then
[tex]\overline z[/tex] which is the conjugate of z is a zero too, because
[tex]\text{if } f(z)=0=az^2+bz+c \text{ then}\\\\\overline {f(z)}=0=a\overline z ^2 +b \overline z + c\\\\\text{meaning } f(\overline z)=0[/tex]
Here, we know that [tex]\sqrt{7}+5i[/tex] is a solution, so
[tex]\overline {\sqrt{7}+5i}= \sqrt{7}-5i[/tex] is a solution too.

The number of customers to visit a local small businesses 51,200 and has been continuously declining at a rate of 3.8 each year what is the approximate number of customers that visit the business in 14 years
Answer:
=30076 customers
Step-by-step explanation:
Number of customer= 51,200
rate of declination=3.8 %= 0.038
We will use the expresion below in calculating the approximate number of customers that visit the business in 14 years.
A=Pe^(rt)
Where P=initial amt,
r=annual rate of growth or decline,
A=amount after t years.
37800=Pe^.017t
51200=Pe^0.038
P= 51200/e^(0.038*14)
But e^(0.038*14)= 1.7023
P= 51200/1.7023
P=30076
Approximate number of customers that visit the business in 14 years≈30076

A city currently has 60 family-owned restaurants. In the future, it is estimated that the number of those restaurants will decline at a rat of 18% per year. Based on that estimate, what is the fewest number of years it will take for there to be less than 20 family-owned restaurants in the city? A.1 B. 3 C. 4 D. 6
The correct answer is D. 6
Explanation:
To know precisely how the number of restaurants in the city decreases over time, it is necessary to determine the 18% of the total of restaurants each year and to subtract this number. The process year per year is shown below:
First-year- 60 restaurants- Find the percentage by writing the known value and using cross multiplication
[tex]60 = 100[/tex] %
[tex]x = 18[/tex]%
[tex]x 100 = 60 x 18[/tex]
[tex]x = \frac{1080}{100}[/tex]
[tex]x = 10.8[/tex] Number of restaurants that were closed
[tex]60-10.8 = 49.2[/tex] New total
Second-year - 49.2 restaurants- Repeat te process
[tex]x = \frac{49.2x 18}{100}[/tex] Shortened version of the equation. Total of restaurants, multiplied by percentage and divided into 100 (total percentage)
[tex]x = 8.8[/tex]
[tex]49.2 - 8.8 = 40.4[/tex] New total
Third-year- 40.4 restaurants
[tex]x = \frac{40.4 x 18}{100}[/tex]
[tex]x = 7.2[/tex]
[tex]40.4-7.2 = 33.2[/tex] New total
Fourth-year- 33.2 restaurants
[tex]x = \frac{33.2x 18}{100}[/tex]
[tex]x = 6.3[/tex]
[tex]33.2- 6.3= 26.9[/tex] New total
Fifth-year- 26.9 restaurants
[tex]x = \frac{26.9 x 18}{100}[/tex]
[tex]x = 4.8[/tex]
[tex]26.9-4.8 = 22.1[/tex] New total
Sixth-year- 22.1 restaurants
[tex]x = \frac{22.1x 18}{100}[/tex]
[tex]x= 3.96[/tex]
[tex]22.1-3.9 = 18.1[/tex]
According to this at this rate, it will take at least 6 years for the number of restaurants to be below 20.

if m and n vary directly and m=3 when n=2, what is the value of m when n=4
no
Answer:
m = 6
Step-by-step explanation:
We know that m and n vary directly and that m = 3 when n = 2. How would we find m when n = 4? For starters, we can see that the value of n doubled (we know this because 2 doubled is 4), and since m and n vary directly, when n doubles, so does m so the answer is m = 3 * 2 = 6.
The length of a rectangle is 7 inches less than its width. The perimeter of the
rectangle is 54 inches. Find the length and the width of the rectangle. Explain your
reasoning.
Answer:
8 in.
Step-by-step explanation:
Perimeter of a rectangle, P = 2(L + W)
Value of P = 46.
Length is 7 inches less than the width. This translates to L = W - 7
Substitute L = W - 7 into the perimeter equation, you get
46 = 2(W - 7 + W)
46 = 2(2W - 7)
46 = 4W - 14
4W = 60
W = 60 / 4 = 15 in
L = W - 7 = 15 - 7 = 8 in
The width and length of the rectangle in inches are 17 and 10 respectively.
What is perimeter ?Perimeter is the sum of the lengths of all the sides of a given plane figure.
According to the given question the length of a rectangle is 7 inches less than its width.
Assuming the width of the rectangle is x inches.
∴ From the given data length of the rectangle is ( x - 7) inches.
Given perimeter is 54 inches.
We know perimeter of a rectangle is 2( length + breadth).
∴ 2{ x + ( x - 7) } = 54.
2 { 2x - 7 } = 54
4x - 14 = 54
4x = 54 + 14
4x = 68
x = 17.
So, the width of the rectangle is 17 inches and length of the rectangle is (17 - 7) inches which is 10 inches.

Arthur can throw a ball twice as far as Beatrice. Beatrice can throw a ball one-third as far as Cory. Cory can throw a ball twice as far as Dominick. What is the ratio of the distance of Arthur's throw to Dominicks throw? Detailed answer please!
Answer:
A : D
4 : 3
Step-by-step explanation:
We'll use the first letter of their names as the heading for the ratio.
The first line states:
A : B
2 : 1
The second line states:
B : C
1/3 : 1
The third line states:
C : D
2 : 1
We have three different ratios but we know that they are related to one another so we are going to combine them by equating the common ratio of the different ratios.
Let's look at the ratio with a fraction first.
B : C
1/3 : 1
If we ×3 throughout, this can also be written as:
B : C
1 : 3
Now B in the first and second ratio is the same number and we are able to combine them. We can write them all together like this:
A : B : C
2 : 1 : 3
In the third ratio, C is 2, however in the ratio we have now C is 3. We can make them the same number by ×3 throughout the third ratio and ×2 throughout the ratio we have now.
C : D
2 : 1
6 : 3
A : B : C
2 : 1 : 3
4 : 2 : 6
We can see that our ratio for C is the same number and we can now combine the ratios.
A : B : C : D
4 : 2 : 6 : 3
The question asked for A : D so we can take just the values of A and D.
A : D

Ten children measured how high they could jump. The results they recorded, in inches, were as follows: 8, 9, 8, 6, 8, 12, 9, 10, 11, 16 What is the median of these measures?
A. 8 in.
B. 9 in.
C. 9.5 in.
D. 10 in.
E. None correct
Answer:
b) 9 in
Step-by-step explanation:
To find median arrange the data in ascending order and count the number of data's. if the total number of data is odd number, then (n/2)th term is the median.
If the total number of data is even, then Average of (n/2)th term and (n/2)+1 th term is the median
Ascending order:
6, 8, 8 , 8 , 9 , 9 , 10 , 11 , 12 , 16
total = 10. so even number
Median = average of 5th term and 6th term
=(9+9)/2
= 18/2

if we represent the length of a line by a, how may we represent the length of a line that is 3 inches shorter. If the combined length of the two lines is 15 inches, what is the length of each line?
Answer:
The lines' lengths are: 8 inches and 5 inches.
Step-by-step explanation:
Calling "a" the length of the line, a line that is 3 inches shorter can be written in math terms as:
a - 3
If the combined (added) length of these two lines is 15 inches, then we can write:
a + (a - 3) = 15
a + a - 3 = 15
2 a - 3 = 15
2 a = 15 + 3
2 a = 18
then
a = 18/2 = 9
Therefore, the length of one line is 8 inches, and the length of the shorter line is:
8 - 3 = 5 inches
