Answer:
880 ft.
Step-by-step explanation:
<em>First! We have to establish how many feet the car travels per hour. </em>
60 <em>(number of miles per hour)</em> x 5280 <em>(number of feet in a mile) </em>= 316,800 <em>(number of feet in an hour)</em>
<em>Next, since we know that there are 60 minutes in an hour we are going to divide our "number of feet in an hour" by 60 to get the "number of feet in a minute"</em>
316,800 ÷ 60 = 5280
<em>Once again, we are going to divide our "number of feet in a minute" by 60 to get the "number of feet per second".</em>
5280 ÷ 60 = 88
<em>Finally! We will multiple our "number of feet per second" by 10 to get how many feet the car can travel in 10 seconds.</em>
88 × 10 = 880
<em>So! Our car can travel 880 feet in 10 seconds.</em>

Answer:
x = 78° , y = 115°
Step-by-step explanation:
The angle adjacent to x on the left side is corresponding to 102° , then
x = 180° - 102° = 78°
----------------------------------------
y and 115° are corresponding angles and congruent, then
y = 115°
Answer:
The length of the chord is 16 cm
Step-by-step explanation:
Mathematically, a line from the center of the circle to a chord divides the chord into 2 equal portions
From the first part of the question, we can get the radius of the circle
The radius form the hypotenuse, the two-portions of the chord (12/2 = 6 cm) and the distance from the center to the chord forms the other side of the triangle
Thus, by Pythagoras’ theorem; the square of the hypotenuse equals the sum of the squares of the two other sides
Thus,
r^2 = 8^2 + 6^2
r^2= 64 + 36
r^2 = 100
r = 10 cm
Now, we want to get a chord length which is 6 cm away from the circle center
let the half-portion that forms the right triangle be c
Using Pythagoras’ theorem;
10^2 = 6^2 + c^2
c^2 = 100-36
c^2 = 64
c = 8
The full
length of the chord is 2 * 8 = 16 cm
Answer:
A. 1
Step-by-step explanation:
Since it's g(-4), we have to use the first option because that means that x is equal to less than -4.
3√x + 5
3 √-4 + 5
= 1
