Find the missing length.
9514 1404 393
Answer:
c = √73
Step-by-step explanation:
The Pythagorean theorem tells you that ...
c² = a² + b²
The sides you choose to call 'a' and 'b' don't matter. We can let 'a' be the left side and 'b' be the top side. Then we have ...
c² = 3² +8² = 9 + 64 = 73
Taking the square root gives ...
c = √73
Answer:
c = [tex]\sqrt{73}[/tex]
Step-by-step explanation:
c is the hypotenuse ( side opposite to the right angle )
So,
[tex]c^{2}[/tex] = [tex]8^{2}[/tex] + [tex]3^{2}[/tex] (Pythagoras theorem)
c = [tex]\sqrt{64 + 9}[/tex]
c = [tex]\sqrt{73}[/tex]

Answer: .
Step-by-step explanation: okay so the formula to complete this is (n-2) x 180. Which basically is the number of sides, minus 2, and times that answer by 180. So (12-2)x 180.
Make s the subject of the formula
Answer:
choose option E.
Step-by-step explanation:
Given
t² = 2p + as
.Making s as the subject
as = t² - 2p
s = ( t² - 2p) / a
t² = 2p + as
t² - 2p = as
(t² - 2p)/a = s
s = (t² - 2p)/a , answer = E
Find the 11th term of the geometric sequence 6, -18,54, ...
Answer:
354294
Step-by-step explanation:
a1 = 6, r = -3
an = a1 * r^n-1 (formula)
a11 = 6 * (-3)^11-1
a11 = 6 * 590949 = 354294
a11 = 354294
Find the side length of a square with
area 16/49 square inches.
The side length of this square is equal to [tex]\frac{4}{7}\;inches[/tex]
Given the following data:
Area of a square = [tex]\frac{16}{49}[/tex] square inches.To determine the side length of this square:
In this exercise, you're required to solve for the length of the sides of a square that has an area of [tex]\frac{16}{49}[/tex] square inches.
Formula for the area of a square.Mathematically, the area of a square is calculated by using the formula;
[tex]A=S^2[/tex]
Where;
S is the length of each sides of a square.Substituting the value into the formula, we have;
[tex]\frac{16}{49}=S^2[/tex]
Taking the square root of both sides, we have;
[tex]S=\sqrt{\frac{16}{49}} \\\\S=\frac{4}{7}\;inches[/tex]

A ladder is leaned against a wall that is six feet tall, so that the top of the ladder is resting on the top
of the wall. The ladder is inclined at an angle of thirty degrees. Find the distance from the bottom of
the ladder to the base of the wall. Round your answer to the nearest tenth of a foot. Do not include
units in your answer.
Answer:
[tex]10.4[/tex]
Step-by-step explanation:
The ladder leaning against the wall forms a right triangle with the wall and the ground. Therefore, we can use basic trig for a right triangle to solve this problem.
In a right triangle, [tex]\tan\theta=\frac{\text{opp}}{\text{adj}}[/tex]. Therefore, we have the following equation, where [tex]x[/tex] is distance between the bottom of the ladder to the base of the wall:
[tex]\tan 30^{\circ}=\frac{6}{x},\\x=\frac{6}{\tan 30^{\circ}},\\x\approx \boxed{10.4}[/tex].

Find the measure of angle a.
Answer:
a = 127°
Step-by-step explanation:
The 3 angles lie on a straight line and have a sum of 180°, that is
15° + a + 38° = 180°
53° + a = 180° ( subtract 53° from both sides )
a = 127°

However, Robert receives a $0.13 discount for every friend he refers to during a month. There is also a special new customer discount of 15% off the first month. What is Robert's first month's bill, if he refers 6 friends?
Answer: $20.59
Step-by-step explanation:
0.13 * 6 = 0.78
25 - 0.78 = 24.22
85% * 24.22 = 20.59

Make t the subject of the formula.
Please help.
Answer:
[tex]t = \frac{2-3q}{q+4}[/tex]
Step-by-step explanation:
[tex]q = \frac{2-4t}{t+3}\\\\[/tex]
Cross multiply,
q(t+3) = 2 - 4t
Use distributive property: a*(b + c) =(a*b) + (a*c)
qt + 3q = 2- 4t
qt + 4t + 3q = 2
qt + 4t = 2 - 3q
t(q + 4) = 2 -3q
[tex]t = \frac{2-3q}{q+4}[/tex]
