How many different size triangles can be drawn with angle measures 90°, 45°, and 45°?
A. No triangles
B. Exactly one triangle
C. Exactly two triangles
D. Any number of triangles
Answer:
Step-by-step explanation:
I believe is D because you actually change the measure of two angles as long as the sum of them are 90.

For f(x) = x^2 and g(x) = (x-5)^2 in which direction and by how many units should f(x) be shifted to obtain g(x)?
A.) up 5 units
B.) down 5 units
C.) left 5 units
D.) right 5 units
Answer:
D
Step-by-step explanation:
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then a shift to the left of a units
• If a < 0 then a shift to the right of a units
Thus
(x - 5)² represents a shift of f(x) to the right of 5 units
Mike is grilling steaks for dinner. The grilling surface is shown below. Each steak requires approximately 0.25 square feet of the grill's surface. What is the maximum number of steaks that Mike can grill at the same time? 2.5 feet 2 feet 3.5 feet
Answer: 32 steaks
Step-by-step explanation:
Given data:
Each steak surface requirement = 0.25 square feet of the grill.
Maximum number of steaks mike can grill at
2.5 feet
2 feet and
3.5 feet
Solution.
At 2.5 feet
= 2.5 / 0.25
= 10 steaks
At 2 feet
= 2 / 0.25
= 8 steaks
At 3.5 feet
= 3.5 / 0.25
= 14 steaks
Total number of steaks
= 10 + 8 + 14
= 32 steaks

What is the measure of 1?
95°
90°
80°
85°
Answer:
85°
Step-by-step explanation:
We need to use the angle fact that angles in a quadrilateral add up to 360° and that a right angle is 90°, using this information we can for an equation to find the value of 1. Lets call "1" x so we don't confuse it with an angle. So,
x + 85 + 100 + 90 = 360
In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we took away 90 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.
x + 85 + 100 + 90 = 360
→ Simplify equation
x + 275 = 360
→ Minus 275 from both sides to isolate x
x = 85
The measure of angle '1' is 85°
Answer:
85°
Step-by-step explanation:
∠1+85°+100°+90°= 360°
∠1 = 360°- 275°= 85°
∠1 =85°

The parallelogram shown below has an area of 404040 units^2 2 squared.
Find the missing base.
Question:
The parallelogram shown below has an area of 40 units squared.
Find the missing base.
Answer:
See Explanation Below
Step-by-step explanation:
The question is incomplete as the diagram which shows the dimension of the parallelogram is not attached.
However, I'll give a general explanation on how to get the base of the parallelogram. If you follow this explanation, you'll get the right answer regarding your question.
The area of a parallelogram is calculated as thus.
Area = Base * Height
Given that the area = 40 units²
Let's assume the height of the parallelogram is 10 unit.
All you need to do is to plug in these values in the formula above..
Area = Base * Height becomes
40 = Base * 10
Divide both sides by 10
40/10 = Base * 10/10
4 = Base
Hence, Base = 4 units
Or take for instance the height is 5 units.
You'll still follow the simple steps as it is above.
Area = Base * Height becomes
40 = Base * 5
Divide both sides by 5
40/5 = Base * 5/5
8 = Base
Hence, Base = 8 units

The image of the point (1, -2) after a rotation of 180° about the origin is
(-2, 1)
(2, -1)
(-1, 2)
Answer:
(-1,2)
Step-by-step explanation:
Found answer on brainly.
Answer:
(-1,2)
Step-by-step explanation:
In this problem, the signs are switched because there is a rule to 180 rotation that is (x,y) to (-x,-y).
(1,-2)×(-1x, -1y)= (-1,2) .
if both points were negative, the points would be positive. if they were positive, they would be negative.

The dimensions that could be the box with a volume of 24 cubic centimeters are:
8cm long, 1cm wide, 3cm high
2cm long, 2cm wide, 6cm high
Options A and C are the correct answer.
We have,
To determine if the given dimensions could represent the box with a volume of 24 cubic centimeters, calculate the volume for each option and check if it matches the given volume.
Let's calculate the volume for each option:
Option A:
Length = 8 cm, Width = 1 cm, Height = 3 cm
Volume = Length × Width × Height
Volume = 8 cm × 1 cm × 3 cm
Volume = 24 cubic cm
Option A could be the dimensions of the box
Option B:
Length = 10 cm, Width = 4 cm, Height = 10 cm
Volume = Length × Width × Height
Volume = 10 cm × 4 cm × 10 cm
Volume = 400 cubic cm
Option B does not have a volume of 24 cubic cm.
Option C:
Length = 2 cm, Width = 2 cm, Height = 6 cm
Volume = Length × Width × Height
Volume = 2 cm × 2 cm × 6 cm
Volume = 24 cubic cm
Option C could be the dimensions of the box.
Therefore,
The dimensions of the box with a volume of 24 cubic centimeters are:
8cm long, 1cm wide, 3cm high
2cm long, 2cm wide, 6cm high

Solve dy/dx = (1-x)(1-y)
Answer:
[tex]y=1-e^{c_{2}}}*e^{-x} *e^{x^2}[/tex]
Step-by-step explanation:
We begin with the differential equation [tex]\frac{dy}{dx} =(1-x)(1-y)[/tex]
Firstly, we need to get the [tex]y[/tex] and [tex]dy[/tex] as well as the [tex]x[/tex] and [tex]dx[/tex] on the same sides as each other
To do this, we can multiply each side by [tex]dx[/tex] and divide each side by [tex](1-y)[/tex]
Doing this will give us the following differential
[tex]\frac{1}{1-y} dy=(1-x)dx[/tex]
Now, we can integrate each side
[tex]\int\limits\frac{1}{1-y} \, dy =\int (1-x) \, dx\\\\-ln(1-y)=x-x^2+c_{1}[/tex]
Now, we need to solve for y
[tex]-ln(1-y)=x-x^2+c_{1}\\\\ln(1-y)=x^2-x+c_{2} \\\\1-y=e^{x^2-x+c_{2}} \\\\y=1-e^{x^2-x+c_{2}}\\\\y=1-e^{c_{2}}}*e^{-x} *e^{x^2}[/tex]
