Enter the correct answer in the box. What are the solutions to the equation (x - 21)^2 = 25?
Answer:
x = 26
Step-by-step explanation:
[tex] {(x - 21)}^{2} = 25 \\ x - 21 = \sqrt{25} \\ x - 21 = 5 \\ x = 5 + 21 \\ x = 26[/tex]
Answer:
x = 26, x = 16.
Step-by-step explanation:
(x - 21)² = 25
Expand the factor.
(x - 21)(x - 21) = 25
Multiply using FOIL.
x² - 42x + 441 = 25
Subtract 25 from both sides.
x² - 42x + 416 = 0
Factor.
(x - 26)(x - 16) = 0.
Set both expressions to 0 and solve.
x - 26 = 0
Add 26 to both sides.
x = 26
x - 16 = 0
Add 16 to both sides.
x = 16

Step-by-step explanation:
Please Help! The diagram shows the graph of y=2x+c, where c is a coonstant. Find the value of k.
Answer:
k = 6.5
Step-by-step explanation:
The question relates to the association of the association of the equation of a graph point(s) on the graph
The given equation of the graph, is y = 2·x + c
The value of 'c' is a constant
We note that the value of 'c' can be found when x = 0, as follows;
y = 2·x + c = 2 × 0 + c = c
∴ When x = 0, y = c
From the graph, when x = 0 we have the y-intercept, the point the graph crosses the y-axis, which is the point y = -3
Therefore;
When x = 0, y = -3 = c
∴ c = -3
The equation of the graph becomes, y = 2·x + (-3) = 2·x - 3
y = 2·x - 3
The other given point on the graph is the point (k, 10)
The value k is the x-value when y = 10
Substituting y = 10 in the equation for the graph gives the x-value at the point y = 10 as follows;
10 = 2·x - 3
2·x = 13
x = 13/2 = 6.5
x = 6.5 (when y = 10)
Therefore the point (k, 10) = (6.5, 10)
By comparing the two equal coordinates, we have;
k = 6.5.
A café's annual income depends on x, the number of customers. The function /(x) = 4x2 – 20x
describes the café's total annual income. The function C(x) = 2x2 + 5 describes the total amount
the café spends in a year. The café's annual profit, P(x), is the difference between the annual income and the amount spent in a year.
Which function describes P(x)?
A. P(x)= 2x^2 - 20x - 5
B. P(x)= 4x^3 - 20x^2
C. P(x)= 6x^2 - 20x + 5
D. P(x)= 8x^4 - 40x^3 - 20x^2 - 100x
Answer:B
Step-by-step explanation:
The value of P(x) the difference between the annual income and the amount spent in a year is,
⇒ P(x) = 2x² - 20x - 5
What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
The function f (x) = 4x² – 20x describes the café's total annual income. And, The function C(x) = 2x² + 5 describes the total amount the café spends in a year.
Hence, The value of P(x) the difference between the annual income and the amount spent in a year is,
⇒ P(x) = 4x² - 20x - 2x² - 5
⇒ P (x) = 2x² - 20x - 5
Thus, The value of P(x) the difference between the annual income and the amount spent in a year is,
⇒ P(x) = 2x² - 20x - 5

HELP PLEASE. urgent help needee
Answer:
123 cm^2
Step-by-step explanation:
for the rectangles its
#1 5(4)=20 cm^2
#2 5(7)= 35 cm^2
#3 5(8) = 40 cm^2
for the triangles its
4(7)(.5)(2)= 28 cm^2
4(7)= 28 cm^2
I get the .5 from the triangle area formula
and since the triangles are equal I multiplied it by 2 again so the .5 cancels out.
in the end you add them all up which is 20+35+40+28 = 123 cm^2

Mi tarjeta de crédito está saturada por lo que tanto recurre un préstamo que cobra el 8% mensual por la cantidad que se solicite me prestaron 3500 cuál es la cantidad de que debo pagar al prestamista en un mes para saldar la deuda
Answer:
El valor que debes pagar al prestamista en un mes para saldar la deuda es: 3780.
Step-by-step explanation:
Para encontrar el valor que debes pagar en un mes para saldar la deuda, debes calcular el 8% del valor que te prestaron y este sería el monto de los intereses. Después, debes sumarle esta cantidad al valor que te prestaron:
monto del préstamo= 3500
3500*8%=280

two lines intersect in the figure below. what is the value of x?
Answer:
A. 17
Step-by-step explanation:
The angles are adjacent, meaning they are congruent. So you will set (5x + 6) equal to 91
(5x + 6) = 5x + 6
5x + 6 = 91
5x + 6 - 6 = 91 - 6
5x = 85
5x / 5 = 85 / 5
x = 17

There are 126000 people living in a town. 52920 people in the town own a car. A local environmental group proudly announces 'fewer than 40% of residents own a car'. Is this statement accurate? Give a reason for your answer.
Answer:
False
Step-by-step explanation:
Given that
There are 126000 people living in a town
Out of which 52920 people in the town own a car
So based on this, the group announces that fewer than 40% of residents own a car
We need to find out the statement is correct or not
So here we determine the percentage
= 52,920 ÷ 126,000
= 42%
Since it is more than 40%
So the given statement is false

Is QRST at the right a rectangle? Explain.
Answer:
Right rectangle.
Step-by-step explanation:
The rectangle will be a right rectangle only if the opposite sides are parallel to each other.
This means that RQ should be parallel to ST
And RS should be parallel to QT
Each side can be represented by a line with a restricted domain, and we know that two lines are parallel only if they have the same slope.
Remember that the slope relates to how a change in the x-value makes a change in the y-value.
Then if two segments have, for a fixed change in the x-value, the same change in the y-value, we can conclude that those segments are parallel.
So here to see if the lines are parallel, we just need to compare the changes between the endpoints of each segment.
Let's start with segments QR and TS
First let's look at the segment QR, and let's try to find the difference in the coordinates between R and Q.
In the graph, we can see that R is 3 units above and one unit to the right of Q.
Now let's do the same for the other segment:
In the graph, we also can see that S is 3 units above and one unit to the right of T.
So these two lines will have the same slope:
Only with this, we can conclude that sides QR and TS are parallel.
Now with the other two segments: RS and QT.
Similar to the above case, for the segment RS we can see that S is 4 units at the right and 1 unit below R.
For the segment QT, we can see that T is 4 units at the right and one unit below Q.
So segments RS and QT have the same slope, thus, the segments are parallel.
Then we can conclude that this is a right rectangle.
A 3ft child casts a 2ft shadow at the same time a tree casts a shadow that is 6ft long how tall is the tree?
Answer:
[tex]h_t=9ft[/tex]

Height of child [tex]h_c=3ft[/tex]
Height of child's shadow [tex]h_c_s=2ft[/tex]
Height of tree's shadow [tex]h_t_s=6ft[/tex]
Since position of Sun remains constant
Generally the equation for Height of tree h_t mathematically given by

Write 5.3421 (bar on 21) in p/q form
Answer:
[tex]\frac{52887}{9900}[/tex]
Step-by-step explanation:
We require 2 equations with the repeating 21 placed after the decimal point.
let x = 5.34212121 ( multiply both sides by 100 and 10000 )
100x = 534.2121... → (1)
10000x = 53421.2121... → (2)
Subtract (1) from (2) thus eliminating the repeating 21
9900x = 52887 ( divide both sides by 9900 )
x = [tex]\frac{52887}{9900}[/tex]
