what's the question please explain so I help.
Answer:
9.33 feet = 111.96 inches
Step-by-step explanation:
If we have similar triangles, the rate between matching sides is the same.
So the length of the smaller ladder (18 ft) over the length of the taller ladder (24 ft) is equal to the distance from the bottom of the smaller ladder to the tree (7 ft) over the distance from the bottom of the taller ladder to the tree (x ft):
18 / 7 = 24 / x
x = 7 * 24 / 18
x = 9.33 feet
To find this measure in inches, we just need to multiply by 12:
x = 9.33 * 12 = 111.96 inches
Answer:
Radius length: √5
Standard Form (Equation): (x + 4)^2 + y^2 = 5
Step-by-step explanation:
First we will determine the radius;
Center: (-4, 0)
Point on Circumference: (-2, 1)
d = √(-2 - (-4))^2 + (1 - 0)^2 = √(2)^2 + (1)^2
= √4 + 1 = √5
Therefore the radius is of length √5
Now the equation of a circle is in the form ((x - h)^2 + (y - k)^2) = r^2. The center is in the form (h,k) and r is the radius. Given this our equation would be (x - (-4))^2 + (y - 0)^2 = (√5)^2, or [simplified] (x + 4)^2 + y^2 = 5.

- Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define</u>
tan51° = x/14.8
<u>Step 2: Solve for </u><em><u>x</u></em>
- Multiply 14.8 on both sides: 14.8tan51° = x
- Evaluate: 18.2765 = x
- Rewrite: x = 18.2765
- Round: x ≈ 18.28
Answer:
29/24π
Step-by-step explanation:
To get coterminal angles, you simply have to add or subtract 2π
In this problem, we are looking for a coterminal angle that is between
0 and 2π, so we will add 2π to −19/24π.
−19/24π+2π
=
−19/24π+48/24π
=
29/24π
29/24π
is the answer to the question.
