Answer:
The two triangles are not similar
Step-by-step explanation:
Similar triangles have equal corresponding angles and proportion sides
Ex: If Δ ABC is similar to ΔXYZ, then
m∠A = m∠X, m∠B = m∠Y, m∠C = m∠Z[tex]\frac{AB}{XY}=\frac{BC}{YZ}=\frac{AC}{XZ}[/tex]In the given question
∵ One triangle has angles that measure 45° and 83°
→ Find the measure of the 3rd angle
∵ The sum of the measures of the angles of a triangle is 180°
∴ The measure of the 3rd angle = 180° - 45° - 83°
∴ The measure of the 3rd angle = 52°
∴ The measures of the angles of this triangle are 45°, 83°, 52°
∵ Another triangle has angles that measure 45° and 42°
→ Find the measure of the 3rd angle
∴ The measure of the 3rd angle = 180° - 45° - 42°
∴ The measure of the 3rd angle = 93°
∴ The measures of the angles of this triangle are 45°, 93°, 42°
∵ The two triangles have different measures of 2 angles
→ That means their corresponding angles are not equal
∴ The two triangles are not similar

Write the equation of the piecewise function. Algebra 2
Answer:
C. [tex]y=\begin{cases}2-x&x<0\\5-3x&x\ge 0\end{cases}[/tex]
D. [tex]y=\begin{cases}-2&x<-3\\4&x>-3\end{cases}[/tex]
Step-by-step explanation:
C. The line to the left of x=0 has a slope of -1 and a y-intercept of 2. That portion of the function does not include x=0. The line to the right of x=0 has a slope of -3 and a y-intercept of 5. That portion of the function includes the case x=0.
[tex]\boxed{y=\begin{cases}2-x&x<0\\5-3x&x\ge 0\end{cases}}[/tex]

D. The line to the left of x=-3 is y=-2; the line to the right of there is y=4. The function is not defined at x=-3.
[tex]\boxed{y=\begin{cases}-2&x<-3\\4&x>-3\end{cases}}[/tex]
Which statement that describes show that figure a is congruent to figure b
Answer:
E.
Step-by-step explanation:
Translation: slide of the shape or figure, it does NOT change its shape, size, and form, count how many units the shape moves.
Reflection: flip of the shape, does NOT change its shape, size, and form, either can be flipped or reflected over the x or y axis.
Rotation: turn of the shape, does NOT change its shape, size, and form, either can be rotated counter clock wise left, (opposite of a clock direction), or clockwise, the direction a clock moves right. It can also be rotated 90° (1 turn), 180° (2 turns), 270° (3 turns) or 360° (4 turns). In highschool, you will get introduced to more degrees of rotation, this is just middle school level.

Bruce owns a business that produces widgets. He must bring in more in revenue than he pays out in costs in order to make a profit. • It costs $10 in labor and materials to make each of his widgets. • His rent each month for his factory is $4,000. He sells each widget for $25. What is the smallest number of widgets Bruce needs to sell each month to make a profit?
Answer:
Bruce needs to sell 267 widgets each month to make a profit.
Step-by-step explanation:
From the information given, you can write that the cost of the monthly rent plus the cost in labor and materials to make each widget for the number of widgets is equal to the amount of sales:
10x +4000 = 25x
Now, you can solve for x:
4000 =25x-10x
4000=15x
x= 266.67→267
According to this, the answer is that Bruce needs to sell 267 widgets each month to make a profit.

Step-by-step explanation:
You can solve this with kinematics or with energy.
Using kinematics, given:
v₀ = 600 m/s
v = 200 m/s
Δx = 0.05 m
Find: a
v² = v₀² + 2aΔx
(200 m/s)² = (600 m/s)² + 2a (0.05 m)
a = -3,200,000 m/s²
Given:
v₀ = 600 m/s
v = 0 m/s
a = -3,200,000 m/s²
Find: Δx
v² = v₀² + 2aΔx
(0 m/s)² = (600 m/s)² + 2(-3,200,000 m/s²) Δx
Δx = 0.05625 m
So the bullet needs to travel an additional 0.00625 m, or 0.625 cm.
Using energy, the work done on the bullet equals the change in kinetic energy.
ΔKE = W
½ mv² − ½ mv₀² = Fd
½ m (200 m/s)² − ½ m (600 m/s)² = F (0.05 m)
(-160,000 m²/s²) m = F (0.05 m)
F/m = -3,200,000 m/s²
½ mv² − ½ mv₀² = Fd
½ v² − ½ v₀² = (F/m) d
½ (0 m/s)² − ½ (600 m/s)² = (-3,200,000 m/s²) d
d = 0.05625 m

A number to the 8th power divided by the same number to the 6th power equals 64. What is the number?
The number is
Answer:
4
Step-by-step explanation:
Let the number = X
You have X^8 / X^5
When dividing two numbers with powers, Simplify the expression by subtracting the powers.
8-5=3
so X^8 / X^5 becomes x^3
Now you have x^3 = 64
To find x take the cubic root of 64:
X = ∛64
X = 4
The number is 4
Answer the following question from the picture:
Answer:
x°= 67°. it's from 180-130 then it's added with 63 then again substrated from 180.
Y°= 63°. y° same as 63° below.
z°= 32°. 85 is added with y° which is 148 and it's substrate from 180 which is 32°.

12. Given y-3 = (x + 1), convert it to standard form.
Answer:
x - y = -4
Step-by-step explanation:
Standard Form: Ax + By = C
A is non-negative
Step 1: Define equation
y - 3 = (x + 1)
Step 2: Solve to Standard Form
Add 3 to both sides: y = x + 4Subtract x on both sides: y - x = 4Factor out negative: -(x - y) = 4Divide by -1 on both sides: x - y = -4Select the equivalent expression.
Answer:
The answer is B
Step-by-step explanation:
This is because when you distribute the -4 to 9^6 and 7^-24 you will get 9^-24 and 7^36. Then, you can move the 7^-24 to the denominator because of the negative exponent rule.

the base of the tringle would be 8 and the height would be 7 use pythagorus
Answer:
≈ 10.6 units
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = p(3, - 1) and (x₂, y₂ ) = q(- 5, 6)
d = [tex]\sqrt{(-5-3)^2+(6+1)^2}[/tex]
= [tex]\sqrt{(-8)^2+ 7^2}[/tex]
= [tex]\sqrt{64+49}[/tex]
= [tex]\sqrt{113}[/tex] ≈ 10.6 ( to 1 dec. place )
