5(1 + 4m) – 2m = -13
Answer and Step-by-step explanation:
Solve for m.
First, distribute the 5.
5 + 20m - 2m = -13
Combine like terms.
5 + 18m = -13
Subtract 5 from both sides of the equation.
18m = -18
Divide by 18 to both sides of the equation.
m = -1 <- This is the answer.

Find the distance between the points (-5, -10) and (2, 4).
Answer:
15.65 units
Step-by-step explanation:
Given data
x1=-5
y1=-10
x2=2
y2=4
The expression for the distance between two points is
d=√((x_2-x_1)²+(y_2-y_1)²)
substitute
d=√((2-(-5))²+(4-(-10))²)
d=√(2+5)²+(4+10)²
d=√7²+14²
d=√49+196
d=√245
d=15.65 units
Hence the distance between the points is 15.65 units
A quadratic function y=f(x) is plotted on a graph and the vertex of the resulting parabola is (3,-4). What is the vertex of the function defined as g (x) =f(x+5)?
Answer:
(-2, -4)
Step-by-step explanation:
y = f(x) = ax²+bx +c
given the vertex is (3, -4)
=> the symetry axis: x = 3
x = -b/2a = 3
so, -b = 6a => b = -6a
the function f(x) = x²-6x + 5
g(x) = f(x+5)
g(x) = (x+5)²-6(x+5)+5
g(x) = x²+10x+25-6x-30+5
g(x) = x²+4x
=> a=1, b=4
find the vertex of the function g :
the symetry axis: x= -4/2(1) => x = -2
y = g(-2) = (-2)²+4(-2)= 4-8 = -4
so, the vertex is (-2, -4)
Answer:
(-2, -4)Step-by-step explanation:
Vertex form of a quadratic function:
f(x) = (x - h)² + kWe have (h, k) = (3, -4)
The function f(x) is:
f(x) = (x - 3)² - 4The function g(x) is:
g(x) = f(x + 5) =
(x + 5 - 3)² - 4 =
(x + 2)² - 4
Vertex of g(x) is:
(-2, -4)determine the equation of the circle graphed below
Answer:
The equation would be (x – 3)^2 + (y – 4)^2 = √26^2 or 26.
Step-by-step explanation:
Firstly, we need to find the radius of the circle. In this case, through the Pythagorean theorem, we can find it to be √(9-4)^2 + (4-3)^2 = √25 + 1 = √26.
Therefore, the equation of the circle would be (x – h)^2+ (y – k)^2 = r^2, where h and k are the x and y-coordinates of the center of the circle respectively, and r is the radius. Hence, the equation of this circle would be (x – 3)^2 + (y – 4)^2 = √26^2 or 26.
Hope this helped!
Answer:
(x - 3)² + (y - 4)² = 26Step-by-step explanation:
Equation in standard form:
(x - h)² + (y - k)² = r²,where (h, k) is the center and r- radius
On the graph we have (h, k) = (3, 4)
Find the r² using the distance formula:
r² = ( 4 - 3)² + (9 - 4)² = 1² + 5² = 26The equation is:
(x - 3)² + (y - 4)² = 26Help me pls i'm struggling need help fast!

Answer:
True.
Step-by-step explanation:
This is true with any quadrilateral.
So, in a quadrilateral ABCD,
The pairs of opposite sides is parallel and equal.
For instance:
A = 1, 1
B = 2, 2
C = 3, 3
D = 4, 4
The midpoint of AB is (1+2)/2, (1+2)/2
The midpoint of CD is (3+4)/2, (3+4)/2
And so on and so forth, therefore the midpoints of the two opposite sides bisect the area of the rectangle.

Answer:
is it timed, because i need like 20 mins to answer this question.
Step-by-step explanation:
A Group of students is tracking a friend, John, who is riding a Ferris wheel. They know that John reaches the Maximum height of 11 m at 10 seconds and then reaches the minimum height of 1 m at 55 seconds.
What is the period of the function and what does it represent in this situation?
The period represents how long it takes go from one max to the next max (ie peak to peak). It also represents going from min to min.
======================================================
Explanation:
It reaches the max at 10 seconds, and then it reaches the min at 55 seconds. This is a timespan of 55-10 = 45 seconds. This is exactly half the period. It doubles to 2*45 = 90 seconds. This is the time period between any two points in time when you're at the max height (from one max to the next adjacent max).
So you're at the max height at 10 seconds, then min at 55 seconds, then the max again at 100 seconds. Note how 100-10 = 90.
The period of any trig function is basically telling us when the function or cycle repeats itself. Once we reach the peak again, the ride repeats itself from before.
-----------
Notes:
90 seconds = 1 minute, 30 seconds = 1.5 minutesThe actual heights listed (11 m and 1 m for the max and min respectively) do not play a role in determining the period. So the heights can be anything we want, and the period will stay at 90 seconds.Patty measured the elementary school and made a scale drawing. The scale she used was 7 centimeters = 1 meter
What is the drawing's scale factor?
Simplify your answer and write it as a ratio, using a colon.
Write the scale of the drawing as a fraction. Put the shorter length in the numerator.
[tex] \frac{7 \: cm}{1 \: cm} \\ [/tex]
First convert the denominator to the same units as the numerator. Write an equivalent fraction with centimeters in the denominator. Since 1 meter is equal to 100 centimeters, multiply the denominator by 100 to get centimeters in the denominator.
[tex] \frac{7 \: cm}{100 \: cm} = \: \frac{7}{100} \\ [/tex]
Write the scale factor as a ratio, using a colon
7/100 → 7:100
The scale factor is 7:100.

Answer:
a) 220.17 cm
b) 2127.12 cm²
Step-by-step explanation:
perimeter = circumference
it is the sum of the inner and the outer arc and the 2 side lines of 25.
we know a full circle has 360 degrees. but we only look at a segment of a circle of 150 out of the total of 360 degrees.
the circumference of a circle is
C = 2×pi×r
the 150 degree part is then
C = 2×pi×r×150/360 = 2×pi×r×15/36 = pi×r×15/18 =
= pi×r×5/6
the radius of the inner circle is 20.
=>
Ci = pi×20×5/6 = pi×50/3
the radius of the outer circle is 20 + 25 = 45
Co = pi×45×5/6 = pi×75/2
so, the total perimeter/ circumference is
C = Ci + Co + 25 + 25 = pi×50/3 + pi×75/2 + 50
= pi×100/6 + pi×225/6 + 50 = pi×325/6 + 50 =
= 220.17 cm
the area of the shaded shape is the area of the large circle segment minus the area of the small circle segment.
the area of a circle is
A = pi×r²
the 150 degree part is then
A = pi×r²×150/360 = pi×r²×5/12
so, for the inner circle that is
Ai = pi×20²×5/12 = pi×400×5/12 = pi×100×5/3 = pi×500/3
for the outer circle that is
Ao = pi×45²×5/12 = pi×2025×5/12 = pi×10125/12 =
= pi×3375/4
so, the total area of the shaded shape is
A = Ao - Ai = pi×3375/4 - pi×500/3 = pi×(10125-2000)/12 =
= pi×8125/12 = 2127.12 cm²
Roger just ran 5 laps. He is at 20% of his goal.
How many more laps until he is finished reaching
his goal?
25 laps The Principal never visited the arts section.
4 laps The Principal never visited the bathroom
15 laps The Principal never visited the History section
20 laps The Principal never visited the office or arts
section.
Answer: 20 laps
Step-by-step explanation:
Given
Roger just ran 5 laps and completes 20% of his goal
Suppose his goal is x laps
So, 20% of x must be equal to 5
[tex]\Rightarrow 20\%\times x=5\\\Rightarrow 0.2x=5\\\\\Rightarrow x=\dfrac{5}{0.2}\\\\\Rightarrow x=\dfrac{50}{2}\\\\\Rightarrow x=25\ \text{laps}[/tex]
So, he needs 20 more laps to complete his goal.

Answer:
k = 8.4, j = 13.1
Step-by-step explanation:
Solve for k:
[tex]tan(40)=\frac{k}{10}\\10(tan(40))=k\\8.4=k[/tex]
Solve for j:
[tex]8.4^2+10^2=j^2\\70.56+100=j^2\\170.56=j^2\\13.1=j[/tex]
Answer:
k = 10 tan (40) = 8.39 (to 2 decimals)
J = 10 / cos(40) = 13.05 (to 2 decimals)
Step-by-step explanation:
It is SOH CAH TOA, or
Sin = Opposite / Hypotenuse
Cos = Adjacent / Hypotenuse
Tan = Opposite / Adjacent
Using SOH CAH TOA,
tan(40) = k/10, so k = 10 tan (40) = 8.39 (to 2 decimals)
cos(40) = 10 / j, so J = 10 / cos(40) = 13.05 (to 2 decimals)

Given that cot A = 16/63 and that angle A is in Quadrant I, find the exact value of cscA in simplest radical form using a rational denominator.
Answer:
Below in bold.
Step-by-step explanation:
cot = adjacent side / opposite side = 16/63
So the hypotenuse = √(16^2 + 63^2)
= √4225
= 65.
So csc A = hypotenuse /opposite side
= 65/63

Answer:
75
Step-by-step explanation:
Essentially this question for the radius as it ask for the distance from the middle of the pit to the outside of the pit.
We are given the diameter (150) which is a straight line through the middle from one end to the other
To find the radius given the diameter you simply divide by 2
So answer = 150/2 = 75
A first number is 4 less than a second number. Four times the first number is 6 more than twice the second. Find the numbers
Answer:
first number = 7
second number = 11
Step-by-step explanation:
A first number is 4 less than a second number
f = s - 4
Four times the first number is 6 more than twice the second
4f = 2s + 6
-----------------------------
Substitute for f = s - 4
4(s - 4) = 2s + 6
distribute
4s - 16 = 2s + 6
subtract 2s from both sides
2s - 16 = 6
add 16 to both sides
2s = 22
Divide both sides by 2
s = 11
Substitute for s = 11 in
f = s - 4
f = 11 - 4
f = 7
