Answer:
36 m
Step-by-step explanation:
Pythagorean Theorem:
a² + b² = c²
27 = b
45 = c
So let's solve
a² + 27² = 45²
a² + 729 = 2025
a² = 1296
√1296 = a
= 36
units = m
36 units

Find x
(Secant tangent angles)
Helppp
Answer:
x = 35
Step-by-step explanation:
The secant- secant angle x is half the difference of the intercepted arcs
The 4 arcs in the circle sum to 360° then
PQ = 360 - (104 + 104 + 111) = 360 - 319 = 41 , then
x = [tex]\frac{1}{2}[/tex] (RS - PQ) = [tex]\frac{1}{2}[/tex] (111 - 41) = 0.5 × 70 = 35

Answer:
Step-by-step explanation:
The given quadratic must be rewritten in standard form before anything else is done: -2x^2 + 8x - 8 = 0. The coefficients of the x terms are {-2, 8, -8}.
The discriminant b^2 - 4ac is therefore (8)^2 - 4(-2)(-8), or 64 - 64, or 0.
A zero discriminant points to two real, equal solutions.

∆ABC is isosceles with legs AB and AC. If AC = 6 cm, and the perimeter is 15 cm, calculate m∠B.
Answer:
m∠B = 75.5°
Step-by-step explanation:
Since AC = 6, then AB = 6 and BC = 15-6-6 = 3
The altitude from A bisects side BC. Let the point of intersection of the altitude and BC be point D. Then BD = 1.5
Cos B = 1.5/6
m∠B = arcccos (1.5/6)
m∠B = 75.5°
If A is the reference angle, which side is the opposite?
AB
BC
AC
Explain your thinking.
Answer:
BC
Step-by-step explanation:
it would be BC because you are basically taking the angle and drawing an arrow to the opposite side. another trick would be choosing an answer choice without the letter in it. also you didn't put what shape so I assumed it was a triangle
Determine the volume of the shape below
Answer:
V = 24513.85 m³Explanation:
Volume of a right cylinder = area of the base × height
V = πr² × h
r = d/2
r = 34/2 = 17 m
V = π × 17² × 27
V = 24513.85 m³

Find the tenth term in each sequence 32, 42, 50, 58, 66
Answer:
106
Step-by-step explanation:
The pattern is +8. 66 is the last number given which is the 5th number. So we need to have five numbers. we can do 8*5=40 and add 40 to 66. Your answer is 106.
A car used 1/ 64 of a gallon of gas to drive 1 4of a mile. At this rate, how many miles can the car travel using 1 gallon of gas?
Answer: 16 miles
Step-by-step explanation:
The car used 1/64 gallons to travel 1/4 miles. To find out how many miles the car can travel using 1 gallon, use direct proportion:
1/64 gallons : 1/4 miles
1 gallon : x miles
Cross multiply:
1/64x = 1/4
x = 1/4 ÷ 1/64
= 1/4 * 64/1
= 16 miles
On one gallon of gas, the car can travel 16 miles.
Which number line shows the solution to 1/4x + 1 <5?
Answer:
Choice 3
Step-by-step explanation:
Solve the inequality for x:
[tex]\frac{1}{4}[/tex]x+1<5
subtract 1 on both sides
[tex]\frac{1}{4}[/tex]x<4
multiply by 4 on both sides
x<16
Choice 3 shows all the numbers that are less than 16, so that is the answer.

Step-by-step explanation:
The perimeter of an inceles triangle is 21 meters. The length of one
sade is 3 meters longer than the length of the other two sides. Find the
length of each side
Answer:
The sides are 6, 6 and 9
Step-by-step explanation:
Isosoles triangles have two sides the same length, s
Here the third side is 3 meters longer (s + 3)
therefor the perimeter is
s + s + (s + 3) = 21
Combine like terms
3s + 3 = 21
Subtract 3 from both sides
3s = 18
Divide both sides by 3
s = 6
s + 3 = 9
The sides are 6, 6 and 9
Ted ate 3 pieces of the pizza. what is the area of the remaining pizza if the diameter of the pizza is 18 inches?
A. 95.4 square inches
B. 381.7 square inches
C. 159.0 square inches
D. 636.2 square inches.
Answer:
C. 159.0 square inches
Step-by-step explanation:
Given that
Ted ate 3 pieces of the pizza
We need to find out the area of the remaining pizza in the case when the pizza diameter is 18 inches
Since the large circular pizza is divided into 8 equal slices
Now the radius of a pizza is
= 18 ÷ 2
= 9 inches
Now the angle subtended by each pizza is
= 360 degrees ÷ 9 inches
= 45 degrees
Now the area of the each pizza is
= [tex]\theta[/tex] ÷ 360 × πr^2
= 45 ÷ 360 × 3.14 × 9^2
= 31.7925
Now the area of the remaining pizza is
= 5 × 31.7925
= 158.9625
= 159 square inches

Look at this diagram:
2x – 5x + 16 = –3(x – 6)
Answer:
0
Step-by-step explanation:
2x – 5x + 16 = –3(x – 6)
2x - 5x + 16 = -3x + 18
-3x + 16 = -3x + 18
0x = 1
x = 0
Answer:
x = ∅
Step-by-step explanation:
2x - 5x + 16 = - 3 (x - 6)
combine like terms
- 3x + 16 = - 3 (x - 6)
distribute
- 3x + 16 = - 3x + 18
subtract 3x from both sides
16 = 18
The equation is false and so x = ∅

Answer:
22x^2+21x+10
brainliest?
Step-by-step explanation:
Answer:
The 4the bubble
Step-by-step explanation:
It is pretty much combining like terms. 22x² is alone since there is no other variable that has an x², so it will be left alone. However, there is 14x and -7x, they both have an x, so that makes them like terms. Combine those and you get 14x minus 7x which is 7x. The number 10 has no other like term to combine with so it can be left alone as well, so just put them all together in the end (simplify). Which would be 22x² + 7x + 10

Answer:
vertex = (3, 1 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is calculate as
x = - [tex]\frac{b}{2a}[/tex]
y = x² - 6x + 10 ← is in standard form
with a = 1, b = - 6 , then
x = - [tex]\frac{-6}{2}[/tex] = 3
Substitute x = 3 into the equation for corresponding y- coordinate
y = 3² - 6(3) + 10 = 9 - 18 + 10 = 1
vertex = (3, 1 )
