Answer:
Step-by-step explanation:
The process here is to find out how far the tire travels in one rotation, then multiply that by 100. That means we need to find the circumference of the tire since the circumference tells us how far around the outside of the tire it is in inches.
C = πd where d is the diameter of the tire.
C = 3.1415(26) so
C = 81.679 inches. Multiply that by 100 to get
8167.9 inches, which in miles is a little over 1.5 miles

Answer:
A)-19,15,-9,-1,9
Step-by-step explanation:
that's the answer when I compute it
===================================================
Explanation:
If we plug in x = -2, then we get,
y = x^2 + 7x - 9
y = (-2)^2 + 7(-2) - 9
y = 4 - 14 - 9
y = -10 - 9
y = -19
So x = -2 leads to y = -19. The answer is between A and D.
---------
If you repeat those steps for x = -1, then you should get y = -15
Then x = 0 leads to y = -9
x = 1 leads to y = -1
Finally, x = 2 leads to y = 9
The outputs we get are: -19, -15, -9, -1, 9 which is choice A
Choice D is fairly close, but we won't have a second copy of -15, and we don't have an output of -19.

Let H represent the number of hats and S represent the number of sweatshirts.
What equation relates S and H to the total Money earned?
205 + 10H = 500
105 + 20H - 500
105 = 500
10H - 400
Answer:
The answer is 20s+10h=500
Step-by-step explanation:
The reason is because 20 times 20=400 and then 10 times 10= 100 then you add those together and get $500
For which function does f decrease by 15% every time x increase by 1? A: f(x)= 0.15^x B: f(x)=8.5^x C: f(x)=15^x. D: f(x)=85^x
Answer:
[tex]f(x) = (0.85)^x[/tex]
Step-by-step explanation:
Exponential amount of decay:
The equation for an amount that decays exponentially has the following format:
[tex]A(x) = A(0)(1 - r)^x[/tex]
In which r is the decay rate, as a decimal.
Decrease by 15%
This means that [tex]r = 0.15[/tex]. So
[tex]f(x) = (1 - r)^x = (1 - 0.15)^x = (0.85)^x[/tex]
So
[tex]f(x) = (0.85)^x[/tex]

Answer:
R = 101
S = 131
Step-by-step explanation:
First, you will want to get your angle T. Since T is on the same line as the angle with 128 degree, you can easily find angel T. They are supplementary angels and form 180.
T=180-128
T=52
You also know that all angles in a triangle equal to 180
Use that to find angle S
180 = R+S+T
180 = 79 + S + 52
180 - 79 - 52 = S
49 = S, exterior S = 180-49 = 131
Exterior R = 180 - 79 = 101
Now add all your exteriors

Anybody have the correct Answer for this math problem?
Answer:
Teorema de Pitágoras
Step-by-step explanation:
Answer is 9.
Please Help! Answer full step by step.
Triangle ABC has vertices A(- 3, - 4), B(16, - 2) and C(13, - 10) . Show algebraically that ABC is a right angled triangle.
Triangle ABC has the three sides AB, BC, and AC.
Let's find the slope of each line. We'll use the slope formula
Let's start with the slope of line AB.
A = (-3, -4) = (x1,y1)
B = (16, -2) = (x2,y2)
m = slope
m = (y2-y1)/(x2-x1)
m = (-2-(-4))/(16-(-3))
m = (-2+4)/(16+3)
m = 2/19
The slope of line AB is 2/19. I'll keep it in fraction form.
We'll use this later, so let p = 2/19.
---------------
Repeat those steps to find the slope of BC
B = (16, -2) = (x1,y1)
C = (13, -10) = (x2,y2)
m = (y2-y1)/(x2-x1)
m = (-10-(-2))/(13-16)
m = (-10+2)/(13-16)
m = -8/(-3)
m = 8/3
The slope of line BC is 8/3.
Let q = 8/3 so we can use it later.
---------------
Now find the slope of line AC.
A = (-3, -4) = (x1,y1)
C = (13, -10) = (x2,y2)
m = (y2-y1)/(x2-x1)
m = (-10-(-4))/(13-(-3))
m = (-10+4)/(13+3)
m = -6/16
m = -3/8
The slope of line AC is -3/8
Let r = -3/8.
---------------
To recap everything so far, we have
p = slope of line AB = 2/19q = slope of line BC = 8/3r = slope of line AC = -3/8We can see that,
p*q = (2/19)*(8/3) = 16/57q*r = (8/3)*(-3/8) = -1p*r = (2/19)*(-3/8) = -6/152 = -3/76Of those slope multiplications, q and r multiply to -1 is what we should focus on. If two slopes multiply to -1, then their lines are perpendicular. This applies to any perpendicular lines where neither line is vertical, and neither is horizontal.
The fractions 8/3 and -3/8 are negative reciprocals of one another. We flip the fraction and flip the sign from positive to negative, or vice versa. This is another way to see we have perpendicular slopes.
So in short, we've shown that BC and AC are perpendicular, and therefore triangle ABC is a right triangle.
----------------------------------------------------------------
To solve this problem a completely different way, we could follow this outline:
Step 1) Find the length of each side AB, BC, and AC. Use the distance formula. Step 2) Apply the pythagorean theorem converse. If you can show a^2+b^2 = c^2 is true, then the triangle with sides a,b,c is a right triangle, where c is the longest side (hypotenuse) opposite the right angle.Through step 1, you should find that,
AB = sqrt(365)BC = sqrt(73)AC = sqrt(292)Let a = sqrt(73), b = sqrt(292), c = sqrt(365). You should find that a^2+b^2 = c^2 is a true statement based on those values, and therefore we have a right triangle. The longest side is AB = sqrt(365), making angle C to be the 90 degree angle. The diagram is shown below. I used GeoGebra to make the diagram.

Step-by-step explanation:
The first graph shows a dot on .5 and the recipes calls for half a cup of sugar.
Answer:
Step-by-step explanation:
[tex]f=\frac{1}{2}s[/tex] is the graph of a straight line with a slope of 1/2. This implies that for every cup of sugar, 1/2 a cup of flour is needed. This also implies what the graph looks like in a coordinate plane. Slope is defined as rise over run, or y over x, so if our slope is 1 over 2, from the origin we go up 1 unit and over 2 units along the length of the whole line. The only graph that displays this slope is graph A.

Which statement make correctly uses limits determine a vertical asymptote of G(x)=-7(x-5)^2(x+6)/(x-5)(x+5)
Answer:
There is a vertical Asymptote at x = 5 because [tex]\lim_{x \to 5^{-} } G(x) = \infty\\lim_{x \to 5^{+} } G(x) = -\infty[/tex]
There is a vertical Asymptote at x = -5 because [tex]\lim_{x \to -5^{-} } G(x) = \infty\\\lim_{x \to -5^{+} } G(x) = -\infty[/tex]
Step-by-step explanation:
The exact question is as follows :
Given - G(x) = -7(x-5)^2(x+6)/(x-5)(x+5)
To find - Which statement make correctly uses limits determine a vertical Asymptote of G(x)
Solution -
Vertical Asymptotes are vertical lines which correspond to the zeroes of the denominator of a rational function.
Here the given function is the rational function
Denominator of G(x) = (x - 5)(x + 5)
So,
Put denominator = 0, we get
(x - 5)(x + 5) = 0
⇒x = 5, -5
∴ we get
G(x) has vertical Asymptotes at x = 5 and x = -5
Now,
At x= 5
[tex]\lim_{x \to 5^{-} } G(x) = \infty\\\lim_{x \to 5^{+} } G(x) = -\infty[/tex]
And
At x = -5
[tex]\lim_{x \to -5^{-} } G(x) = \infty\\\lim_{x \to -5^{+} } G(x) = -\infty[/tex]
∴ we get
There is a vertical Asymptote at x = 5 because [tex]\lim_{x \to 5^{-} } G(x) = \infty\\lim_{x \to 5^{+} } G(x) = -\infty[/tex]
There is a vertical Asymptote at x = -5 because [tex]\lim_{x \to -5^{-} } G(x) = \infty\\\lim_{x \to -5^{+} } G(x) = -\infty[/tex]

Applying the Pythagorean theorem, solve this triangle.
Answer:
20
Step-by-step explanation:
We can use the Pythagorean theorem since this is a right triangle
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
21^2 + b^2 = 29^2
441+b^2 =841
Subtract 441 from each side
441 +b^2 -441 = 841-441
b^2 = 400
Take the square root of each side
sqrt(b^2) = sqrt(400)
b =20
