Use the distributive property to remove the parentheses.
9(6-v)
Answer:
[tex]54-9v[/tex]
Step-by-step explanation:
To remove the parentheses by using the distributive law, we need to multiply [tex]9[/tex] to each term within the parentheses.
[tex]9(6-v) = 9(6) +9(-v)[/tex]
[tex]=54-9v[/tex]

Find the slope of the line through the points (2, -2) and (8, -2)
Answer:
0
Step-by-step explanation:
We can find the slope using
m = ( y2-y1)/(x2-x1) where ( x1,y1) and ( x2,y2) are points on the line
m = ( -2 - -2)/(8 - 2)
= ( -2 +2) / ( 8-2)
= 0/6
=0
The slope is 0
The direct distance from Trevino to Lowell is 100 miles, and the direct distance from Lowell to Sun City is 30 miles. To the nearest mile, what is the direct distance from Las Palmas to Lowell?
Answer:
A. 55
Step-by-step explanation:
The direct distance from Las Palmas to Lowell = the altitude or height of the right triangle.
According to the right triangle altitude theorem, thus:
[tex] h = \sqrt{xy} [/tex]
Where,
h = direct distance from Las Palmas to Lowell = ?
x = direct distance from Trevino to Lowell = 100 miles
y = direct distance from Lowell to Sun City = 30 miles
Plug in the values into the equation
[tex] h = \sqrt{100*30} [/tex]
[tex] h = \sqrt{3,000} [/tex]
[tex] h = 55 miles [/tex] (nearest mile)

What is the value of x?
Answer:
x = 6
Step-by-step explanation:
To solve this equation, we need to isolate x. To do that, we need to divide both sides of the equation by 0.5. That gives us:
0.5x=3
x=3/0.5 = 6
Answer:
x=6
Step-by-step explanation:
0.5x÷0.5=3÷0.5
x=3÷0.5
x=6

Answer:
(7 -24√3)/50 = 0.14 -0.48√3
Step-by-step explanation:
Sine is negative and cosine is positive in the 4th quadrant, so ...
sin(α) = -√(1 -cos(α)²) = -√(1 -576/625) = -7/25
Then the cosine of the angle sum is ...
cos(α +5π/6) = cos(α)cos(5π/6) -sin(α)sin(5π/6)
= (24/25)(-√3/2) -(-7/25)(1/2)
= (7 -24√3)/50 = 0.14 -0.48√3
The city of Gary has a population of 75,282. Approximately 34.78% of Gary residents have a higher education degree. How many people in Gary have a higher education degree? Round to a whole person.
Answer:
26183
Step-by-step explanation:
Given that,
The population of the city of Gary is 75,282. 34.78% of Gary residents have a higher education degree.
We need to find the no of people in Gary have a higher education degree. It can be simply calcualted by taking 34.78% of 75,282 as follows :
[tex]P=75282\times 34.78\%\\\\ =75282\times \dfrac{34.78}{100}\\\\=26183.07[/tex]
or
P = 26183
So, there are 26183 people in Gary have a higher education degree.

Suppose a stock drops in value by 60% one week, then increases in value the next week by 75%. Is the value higher or lower than where it started
Answer:
Lower
Step-by-step explanation:
Use the number 100 to see how the value changes:
First, calculate the 60% drop:
100(0.4)
= 40
Then, calculate the 75% increase:
40(1.75)
= 70
So, since 70 is smaller than 100, the value is lower than where it started.
x^2-9x=-2 quadratic equation
Answer:
Step-by-step explanation:
x^2-9x=-2 move the -2 over and set to 0
x^2-9x+2=0
This can not be factored, so use the quadratic formula.
x=9±√73 /2
Answer:
x = 9 + sqrt(73) / 2
x = 9 - sqrt(73) / 2
Step-by-step explanation:
Assuming you want to factor and find its roots:
[Put all the terms in the left hand size]
x^2-9x+2=0
[Use the quadratic formula; Not factorable and too tedious for completing the square]
x = -b +- sqrt(b^2-4ac) / 2a
x = 9 + sqrt(9^2 - 4(1)(2)) / 2(1)
x = 9 - sqrt(9^2 - 4(1)(2)) / 2(1)
x = 9 + sqrt(73) / 2
x = 9 - sqrt(73) / 2

What are the roots of the equation x(x + 10) +20 = -5?
B5.5
C. 10,2
Answer:
[tex]x=-5[/tex]
Step-by-step explanation:
STEP 1: Simplify each term.
[tex]x^2+10x+20=-5[/tex]
STEP 2: Move 5 to the left side of the equation by adding it to both sides.
[tex]x^2+10x+20+5=0[/tex]
STEP 3: Add 20 and 5.
[tex]x^2+10x+25=0[/tex]
STEP 4: Factor using the perfect square rule.
[tex](x+5)^2=0[/tex]
STEP 5: Set the x+5 equal to 0.
[tex]x+5=0[/tex]
STEP 6: Subtract 5 from both sides of the equation.
[tex]x=-5[/tex]
Calculate the slope of a line that passes through the points (3, -20) and (5,8).
O 6
O4
O 14
O 26
Answer:
Option 3: 14 is the correct answer.
Step-by-step explanation:
Slope is denoted by m and is calculated using the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Here
(x1,y1) are the coordinates of first point and
(x2,y2) are the coordinates of second point
Given
(x1,y1) = (3, -20) and
(x2,y2) = (5,8)
Putting the values in the formula, we get
[tex]m = \frac{8-(-20)}{5-3}\\m = \frac{8+20}{2}\\m = \frac{28}{2}\\m = 14[/tex]
The slope of line passing through points (3, -20) and (5,8) is 14.
Hence,
Option 3: 14 is the correct answer.
The fourth term of a geometric progression is 4 and the seventh term is 32/125. Find the first term, the common ratio and the sum of the first nth terms. Hence, deduce the sum to infinity.
Answer:
common ratio is 2/5
First term is 125/2
The sum of the first n terms is: [tex]S_n=\frac{125}{2} \, \frac{1-(2/5)^n}{3/5}[/tex]
The infinite sum is: [tex]S_\infty =\frac{625}{6}[/tex]
Step-by-step explanation:
The 4th term is 4, and the seventh term is 32/125 so we use the definition of nth term of a geometric sequence to create the following two equations:
[tex]a_4=a_1\,*\,r^{4-1} = a_1\,*\,r^3\\4=a_1\,*\,r^3\\and\\a_7=a_1\,*\,r^{7-1} = a_1\,*\,r^6\\\frac{32}{125} = a_1\,*\,r^6[/tex]
Now we divide a7 by a4 to get rid of a1 and work on determining the common ratio of the sequence:
[tex]\frac{a_7}{a_4} =\frac{8}{125} =\frac{a_1\,r^6}{a_1\,r^3} =r^3\\then\\r=\sqrt[3]{\frac{8}{125} } =\frac{2}{5}[/tex]
So, the common ratio is 2/5
we can now determine the first term:
[tex]a_4=4=a_1\,*\,(2/5)^3\\a_1=\frac{125*4}{8} =\frac{125}{2}[/tex]
The sum of the first n terms is given by the formula:
[tex]S_n=\frac{125}{2} \, \frac{1-(2/5)^n}{1-(2/5)} \\S_n=\frac{125}{2} \, \frac{1-(2/5)^n}{3/5}[/tex]
and therefore, the infinite sum is:
[tex]S_\infty = a_1\,\frac{1}{1-r} = \frac{125}{2} \,\frac{5}{3} =\frac{625}{6}[/tex]
A baby is 18in long at birth and 27 in long in ten months

What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.equation modelling : Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis and results of the given problemGiven is that a baby is 18in long at birth and 27in long in ten months
At birth, the length of baby = 18 inches.
After 10 months, the length of the baby = 27 inches.
Increase in length per month will be -
r = (27 - 18)/(10 - 0)
r = 9/10
r = 0.9 inch
Therefore, the length of the baby will increase 0.9 inch per month.

If u= 1 + i and v= 1 - i, what is u + V?
Answer:
u + v = 2
Step-by-step explanation:
If v = 1 - i
and u = 1 + i
Then we have to calculate and value of u + v
Now u + v = ( 1 - i ) + ( 1 + i )
= (-i + i) + ( 1 + 1 ) [by adding like terms]
= 0 + 2
= 2
= u + v = 2

Answer:
n=8
Step-by-step explanation:
3n=−8+4n
Simplify both sides of the equation.
3n=4n−8 (there isn't so It stays the same.
Subtract 4n from both sides.
3n−4n=4n−8−4n
−n=−8
Divide both sides by -1.
−n/-1 =−8/-1
