Find the surface area of the prism.
9 m
5 m. 12m
Answer:
the surface area of the prism is equal to 202 m^2
Step-by-step explanation:
The surface area of the prism is equal to
SA=2B+Ph
where
B is the area of the base
P is the perimeter of the base
h is the height of the prism
Find the area of the base B
B=LW=4*5=20m^2
Find the perimeter of the base P
P = 2(L+W) = 2 (4+5) = 18 m
Find the surface area ---->
SA = 2B + Ph = 2(20) + 18(9) = 202 m^2
btw m^2 is stand for square meter, also called the meter squared! (just if ur wondering)
pls help and do quick!
Answer:
If 50.24cm = Circumference
Radius = 8cm
If 50.24cm^2 = Area
Radius = 4cm
Step-by-step explanation:
50.24cm what? Circumference? Area?
π = 3.14
2πr = Circumference
50.24 / 2π = r
r = 8
πr^2 = Area
50.24 / π = r^2
r^2 = 16
r = 4
Graph the piecewise function.
Answer: First Option is correct.
Step-by-step explanation:
Since we have given that
\begin{gathered}f(x)=-x+1,x < 0\\\\f(x)=x+1,x\geq 0\end{gathered}
f(x)=−x+1,x<0
f(x)=x+1,x≥0
If we let f(x)=y
then, y=x+1 and y=-x+1
Put x=0,
\begin{gathered}y=0+1\\\\y=1\end{gathered}
y=0+1
y=1
so, there must be coordinate on y -axis at 1.
and it must take Ist and II nd quadrant .
Hence, First Option is correct.

What is the vertex and axis of symmetry?
Check the picture below.
now, the Range and Domain are both assuming the lines goes no further, keeping in mind that most lines go to infinity.
the x-intercepts are just where the graph intersects or touches the x-axis.
the y-intercepts are just where the graph intersects or touches the y-axis.
vertex is simply where it makes the U-turn, and axis of symmetry is simply most of the time the x-coordinate of the vertex, of namely the line where the graph begins making a mirror image.

Answer:
4 and 5 not functions 6 function
Step-by-step explanation:
In a function, each x value can only have one y value. To test this, you can try the vertical line test. Put a vertical line on the function; if it touches only one point the graph is a function. For graph 4, the x value of 3 has y values of 1 and 4 so it is not a function. For graph 5, the x values of 1 and 5 have many y values so the graph isn't a function. For graph 6, each x value has only one y value so it is a function.
Answer:
4. Not a function
5. Not a function
6. Function
Step-by-step explanation:
1 -3 (correct!)
Functions do NOT have repeating x-values. Hence why you were able to determine if # 1-3 are fuctions or not.
4. Not a fuction:
(1, 2)
(2, 3)
(3, 1)
(3, 4)
As we can see, both points have the same x-values. Therefore, not a function.
5. Using our knowledge about functions, we can quickly tell that this graph is NOT a fuction.
There are many points that fall under the same x-value.
6. Function:
(1, 2)
(2, 2)
(3, 3)
(4, 4)
No repeating x-values. Therefore, a function.

Answer:
H(d) = 0.3d + 12
Step-by-step explanation:
It started at 12 inches.
Then it grew 0.3 inches per day.
Let d = number of days.
The growth is 0.3 d.
Add the growth to the original length, to get 0.3d + 12.
Answer: H(d) = 0.3d + 12

The measures of two supplementary angles have a ratio of 4:5. What is the measure of the larger angle?
The measure of the larger angle is ____
Answer:
100 DEGREES
Step-by-step explanation:
Supplementary means they add to 180 degrees
4x + 5x = 180
x = 20
smaller angle 4 (20) = 80
learger angle 5 (200 = 100
Marco travels from his house to the beach. The total distance he travels
is 120 miles. In the first hour, Marco traveled 54 miles. What percent of
the distance did he travel the first hour?
Answer:
45%
Step-by-step explanation:
Since he drove 54 miles out of 120 in the first hour, the equation for this would be 54/120×100. This equals 45 and that is the percentage
Find f(2) if f(x) = (-2x)^2 / (7x-4)
Answer:
4/3

f(2) = (-2*2)^2 / (7(2))-4)
f(2) = (-4)^2 / 14-4
f(2) = 16 / 12
f(2) = 4 / 3

11-3 = 8
11+ 3 = 14
14 +8 = 22
the two numbers are 8 and 14
Given the objective Function: Revenue = 75x+85y and the critical points: (0,0) (180,120) (300,0)
Answer
(180,120)
Cannot be determined
Step-by-step explanation:
Fax
The critical point with the maximum revenue is at (180,120)
How to determine the critical point with the maximum revenue?The objective function is given as:
Revenue = 75x+85y
The critical points are (0,0) (180,120) (300,0)
Substitute these points in the objective function.
Revenue = 75(0)+ 85(0) = 0
Revenue = 75(180)+ 85(120) = 23700
Revenue = 75(300)+ 85(0) = 22500
The maximum revenue is 23700.
Hence, the maximum revenue is at point (180,120)

6. Hadila is 2 years younger than Kai Yee. Kai Yee's father's age is the square of Hadila's age. If Kai Yee is p years old, calculate the total age of the three of them. Express your answer in the form of algebraic expression.
ANSWER: p^2 - 2p + 2
Step-by-step explanation:
Total age of three = p + p-2 + (p-2)^2
= 2p-2 + p^2-4p+4
= p^2 - 2p + 2
find the area of a circke with a radius of 9 mm. round to the nearest tenth. use 3.15 or 22/7 for Pi.
Answer:
254.3 mm^2
Step-by-step explanation:
Area of a circle: A = π*r^2
π (pi) = 3.14
r (radius) = 9 mm
Substitute 3.14 for pi and 9 for radius:
A = π*r^2
A = 3.14*9^2
A = 3.14*81
A = 254.34 mm^2
Round to the nearest tenth:
254.34 ==> 254.3
Therefore, our final answer is 254.3 mm^2
