An isosceles right triangle has two congruent angles and a right angle
It is true that the base angle of an isosceles right triangle is 45 degrees
How to determine the base angle?From the question, we understand that:
Triangle type = isosceles right triangle
The sum of angles in a triangle is:
x + y + z = 180
Assume the triangle is right-angled at z.
So, we have;
z = 90
The equation becomes
x + y + 90 = 180
Subtract 90 from both sides
x + y = 90
The triangle is an isosceles triangle.
So, we have: x = y
The equation becomes
x + x = 90
2x = 90
Divide by 2
x = 45
Hence, it is true that the base angle of an isosceles right triangle is 45 degrees

On a coordinate plane, how are the locations of the points (-5 , -3) and (5 , -3) related? A. Reflection across both axes B. Locations unrelated C. Reflection across the x-axis D. Reflection across the y-axis
Answer:
D. Reflection across the y-axis
Step-by-step explanation:
In the points (-5, -3) and (5, -3), first, notice that the y-coordinates are the same. However, the x-coordinates are positive and negative, meaning one will be on the left side of the y-axis and one will be on the right side of the y-axis, bringing us to answer D. Graph proof is also attached.

Find the surface area
Answer = 221.52cm²
Step-by-step explanation:
Surface area of a hexagonal pyramid = B × H ÷ 2
Where,
b = 6
h = 5.2
⇒ 6 × 5.2 ÷ 2 = 15.6
⇒ 15.6 × 5.2 = 81.12
⇒ 6 × 9 ÷ 2 ⇒ 54 ÷ 2 = 27
⇒ 27 × 5.2 = 140.4
140.4 + 81.12
= 221.52
Answer:
Step-by-step explanation:
a -> apotham of the hexagon ⇒ a = 3√3 cm
b -> base ⇒ b = 6 cm
s ->slant height ⇒ s= 9 cm
[tex]\text{Area of hexagonal pyramid=3*ab +3*b*s}[/tex]
= 3*3√3*6 + 3*6*9
= 54*1.732 + 162 [√3 = 1.732]

Find the sixth term of the geometric sequence when a4=−8 and r=0.5
A. 4
B. 2
C. -4
D. -2
Answer:
D
Step-by-step explanation:
to find a term in the sequence multiply the previous term by r , then
a₄ = - 8 , so
a₅ = - 8 × 0.5 = - 4
a₆ = - 4 × 0.5 = - 2
The sixth term of the sequence will be negative 2. Then the correct option is D.
What is a geometric sequence?Let a₁ be the first term and r be the common ratio.
Then the nth term of the geometric sequence is given as,
aₙ = a₁ · (r)ⁿ⁻¹
The fourth term (a₄) is negative 8 and the common ratio is 0.5.
Then the sixth term will be
For n = 5, we have
a₅ = a₁ · (r)⁵⁻¹
a₅ = a₁ · (r)⁴
a₅ = a₁ · r³ · r
a₅ = a₄ · r
a₅ = -8 · 0.5
a₅ = -4
Then the sixth term of the sequence will be
a₆ = a₁ · (r)⁶⁻¹
a₆ = a₁ · (r)⁵
a₆ = a₁ · r⁴ · r
a₆ = a₅ · r
a₆ = -4 · 0.5
a₆ = -2
The sixth term of the sequence will be negative 2.
Then the correct option is D.

Number of Headphones Made per Week
Based on this model, which statements are true? Choose ALL that are correct.
When producing 5,000 sets of headphones per week, the weekly earnings is $0.
If production is increased from 3,000 to 4,000 sets of headphones per week, then the weekly earnings will also increa
Producing 2,500 sets of headphones per week will give the maximum amount of weekly earnings.
The maximum possible earnings is about $6,250 per week.
If production is increased from 1,500 to 2,000 sets of headphones per week, then the weekly earnings will also increa
The production graph of the company is a quadratic graph
The true statements about the production graph are:

Producing 5000 sets weekly
From the graph, we have:
(x,y) = (5000,0)
This means that a weekly production of 5,000 sets of headphones give an earning of $0.
Hence, this option is true
Increased production from 3000 to 4000
From the graph, the function value decreases when x increases from 3000 to 4000.
This means that this option is false
Producing 2500 sets
The production of 2500 sets give a maximum earning of $6250
This means that options (c) and (d) are true
Increased production from 1500 to 2000
From the graph, the function value increases when x increases from 1500 to 2000.
This means that this option is true
Hence, the true statements are: (a), (c), (d) and (e)
