what is the value of x?
Answer:
I don't know for sure but is 69 an option? is so that might be it
Answer:
x = 58
Step-by-step explanation:
Given an angle outside a circle formed by a tangent and a secant then
angle = [tex]\frac{1}{2}[/tex] difference of the measures of the intercepted arcs, that is
51 = [tex]\frac{1}{2}[/tex] (160 - x) ← multiply both sides by 2
160 - x = 102 ( subtract 160 from both sides )
- x = - 58 ( multiply both sides by - 1 )
x = 58
A circle is centered at the point (-7, -1) and passes through the point (8, 7). The radius of the circle is units. The point (-15, ) lies on this circle.
Answer:
Part 1) The radius of the circle is [tex]r=17\ units[/tex]
Part 2) The point (-15,14) and the point (-15,-16) lies on the circle
Step-by-step explanation:
step 1
Find the radius of the circle
we know that
To find the radius of the circle calculate the distance between the center of the circle and the point (8,7)
the formula to calculate the distance between two points is equal to
[tex]d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}[/tex]
we have
[tex](-7,-1)\\(8,7)[/tex]
substitute
[tex]r=\sqrt{(7+1)^{2}+(8+7)^{2}}[/tex]
[tex]r=\sqrt{(8)^{2}+(15)^{2}}[/tex]
[tex]r=\sqrt{289}[/tex]
[tex]r=17\ units[/tex]
step 2
Find the equation of the circle
The equation of the circle in standard form is equal to
[tex](x-h)^{2}+(y-k)^{2}=r^{2}[/tex]
where
(h,k) is the center
r is the radius
substitute
[tex](x+7)^{2}+(y+1)^{2}=17^{2}[/tex]
[tex](x+7)^{2}+(y+1)^{2}=289[/tex]
step 3
Find the y-coordinate of the point (-15.y)
substitute the x-coordinate in the equation of the circle and solve for y
[tex](-15+7)^{2}+(y+1)^{2}=289[/tex]
[tex](-8)^{2}+(y+1)^{2}=289[/tex]
[tex]64+(y+1)^{2}=289[/tex]
[tex](y+1)^{2}=289-64[/tex]
[tex](y+1)^{2}=225[/tex]
square root both sides
[tex](y+1)=(+/-)15[/tex]
[tex]y=-1(+/-)15[/tex]
[tex]y1=-1(+)15=14[/tex]
[tex]y2=-1(-)15=-16[/tex]
therefore
The point (-15,14) and the point (-15,-16) lies on the circle

A national study found that a car's value decreases by 15 percent annually. If the car was purchased for 66,000. How much will the car be worth in 10 years?
Answer:
$12,993.71
Step-by-step explanation:
The formula we want for this is exponential decay which is
[tex]A(t)=a(1-r)^t[/tex]
where A(t) is the value of the car after the depreciation, a is the initial value of the car, r is the interest rate at which it depreciates in decimal form, and t is the time in years. We have everything we need to fill in to solve for A(t):
[tex]A(t)=66,000(1-.15)^{10}[/tex]
We will do some simplifying first:
[tex]A(t)=66,000(.85)^{10}[/tex]
First raise .85 to the 10th power to get
A(t) = 66,000(.1968744043)
and then multiply to get
A(t) = $12,993.71
Answer:
$12,993.71
Step-by-step explanation:
First raise .85 to the 10th power to get
A(t) = 66,000(.1968744043)

PLEASE HELP ME WITH THIS QUESTION ITS URGENT ITS ABOUT COMPLETING A EQUATION
Answer:
(x - 2)² + (y +8)² = 49
Step-by-step explanation:
Points to remember
Equation of a circle passing through the point (x₁, y₁) and radius r is given by
(x - x₁)² + (y - y₁)² = r ²
To find the radius
It is given that, center of circle = (-5, -8) and passes through the point (2 -8)
By using distance formula,
r = √[(2 --5)² + (-8 --8)²]
= √7²
r = 7
To find the equation of the circle
Here (x₁, y₁) = (2, -8)
Equation of circle is,
(x - x₁)² + (y - y₁)² = r ²
(x - 2)² + (y - (-8))² = 7²
(x - 2)² + (y +8)² = 49
Answer:
The equation of circle is [tex](x+5)^2+(y+8)^2=49[/tex].
Step-by-step explanation:
The standard form of a circle is
[tex](x-h)^2+(y-k)^2=r^2[/tex] .... (1)
where, (h,k) is the center of the circle and r is the radius.
It is given that the center of the circle is (-5,-8). it means h=-5 and k=-8.
The circle passes through the point (2,-8). So, the radius of the circle is the distance between point (-5,-8) and (2,-8).
[tex]r=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]r=\sqrt{(2-(-5))^2+(-8-(-8))^2}[/tex]
[tex]r=\sqrt{7^2+0}[/tex]
[tex]r=7[/tex]
Substitute h=-5, k=8 and r=7 in equation (1), to find the equation of circle.
[tex](x-(-5))^2+(y-(08))^2=(7)^2[/tex]
[tex](x+5)^2+(y+8)^2=49[/tex]
Therefore the equation of circle is [tex](x+5)^2+(y+8)^2=49[/tex].
Let f(x) = x + 7 and g(x) = x − 4. Find f(x) ⋅ g(x).
For this case we have the following functions:
[tex]f (x) = x + 7\\g (x) = x-4[/tex]
We must find the product of the functions:
[tex]f (x) * g (x) = (x + 7) (x-4)[/tex]
We apply distributive property:
[tex]f (x) * g (x) = x ^ 2-4x + 7x-28\\f (x) * g (x) = x ^ 2 + 3x-28[/tex]
Finally, the product of the functions is:
[tex]x ^ 2 + 3x-28[/tex]
Answer:

58.56 gallons of milk,a person will drink in a leap year.
What is leap year?
A Leap Year has 366 days (the extra day is the 29th of February).
How to know if it is a Leap Year:
Leap Years are any year that can be exactly divided by 4 (such as 2016, 2020, 2024, etc)
except if it can be exactly divided by 400, then it is (such as 2000, 2400)
How many galllons will a person drink in a leap year?
We have given,
Average person drinks 16 ounces of milk in 1 day.
We have to find milk consume by average person in 366 days in gallons.
We know, 1 ounce (oz)=0.01 gallons
So, 16 ounce = 16×0.01 gallons
=0.16 gallons
We can say milk consume in one day = 0.16 gallons
Therefore,milk consume in 366 days(in gallons)=366×milk consume in 1 day.

Answer:
d. 12 units, 14 units, 10 units
Step-by-step explanation:
The side lengths differ by 2 units from one to the next larger one:
(2t+2) - (2t) = 2
(2t+4) - (2t+2) = 2
So, you're looking for answer numbers that can make a sequence with differences of 2, and that add to 36. Only the last choice matches that description.
_____
You can solve this "directly" by adding up the side lengths and setting that result to the perimeter length.
(2t+2) + (2t+4) + (2t) = 36
6t +6 = 36 . . . . . collect terms
6t = 30 . . . . . . . . subtract 6
t = 30/6 = 5 . . . . divide by 6
The shortest side is 2t, so is 2·5 = 10 units. Only the last answer choice matches this.
Side lengths are 12 units, 14 units, 10 units.

Caroline replaced the original factory tires (P240/75 R 16) on her pickup truck with P290/70R16 tires. If the speedometer on Cassie’s truck reads 60 mph, how fast is Cassie actually traveling?
Cassie is traveling 65.7 mph
Cassie is traveling 66.6 mph
Cassie is traveling 68.9 mph
Cassie is traveling 63.6 mph
Answer:
Cassie is traveling 63.6 mph
Step-by-step explanation:
If the three numbers, left to right, are A, B, C, then the tire radius in millimeters is ...
A×B/100 + 12.7×C
For the factory tires, the tire radius is ...
240·75/100 + 12.7·16 = 180 +203.2 = 383.2 . . . . millimeters
For the replacement tires, the tire radius is ...
290·70/100 +203.2 = 406.2 . . . . millimeters
The speedometer is calibrated based on the number of revolutions the tire makes in a given time period. If the truck goes farther for each revolution, its speed is higher by the same proportion.
If the speedometer on the truck with these replacement tires reads 60 mph, the actual speed is ...
(406.2/383.2)×60 mph = 63.6 mph
