Answer:
140 cm^2
Step-by-step explanation:
each lateral = 5×7 = 35 cm^2
there are 4 lateral,
so total area = 4×35 = 140 cm^2
Answer: 140cm2
Step-by-step explanation:
The base and top are not included in the lateral area so all the other faces have the same surface area which is 7x5=35cm2. Now multiply this by four sides which is 35x4=140cm2.

Part 1 -Sample roller coasters warm up:
Fanny and Elena enjoy roller coasters. Whenever a new roller Coaster opens near their town,
they try to be among the first to ride. One Saturday, the two friends decide to ride a new
coaster. While waiting in line, Fanny notices that part of this coaster resembles the graph of a
polynomial function that they have been studying in their math class.
The brochure for the coaster says that, for the first 10 seconds of the ride, the height of the
coaster can be determined by H(t) = 0.3t-t+ 21t where t is the time in seconds and h
is the height in feet.
1. Find the height of the coaster at t = 0 second. Explain why this answer makes sense.
2. Evaluate H(10) to find the height of the roller coaster at t = 10 seconds.
3. Graph H(t) using a calculator or a computer program for t=0 to t = 10 seconds.
4. During the first 10 seconds of the ride, is the rollercoaster going up and/or going down?
Is the slope constant?
Answers
Answer:
Step-by-step explanation:
h(t) = 0.3t -t +21t , t=time and h=height
1.
at t=0 the hight is h=0
h(0) = 0.3*0 -0 +21*0 = 0
It makes sense that at the time 0 seconds when the rollercoaster did not leave the hight is 0 feet.
2.
for t=10 substitute t with 10
h(10) = 0.3*10 -10 +21*10 = 3 -10 +210 = 203
3. see graph
4. the rollercoaster is going up
If the area of a trapezoid below is 234 square units, what is the value of x?
Answers
Answer:
the formula for the area of a trapezoid is area =(top + bottom)/2 x height
using the given information we can solve
for x:
234 = (20+32)/2 X
234 = 52/2 X
234 = 26 X
X=234/26

What do you think your favorite way of solving an equation will be and why?
(graphing, substitution, elimination)
Answers
Answer:
Elimination
Step-by-step explanation:
Elimination is a process which involves complete removal of one of the variables in a given equation, so as to first determine the value of the other variable.
For example in solving a simultaneous equation, applying the elimination method is easily understood, straight forward and simple to use. Once the logic behind the process is well understood and followed, errors can easily be avoided.
Therefore my favorite way of solving an equation would be by applying the elimination method because it is easy and direct to apply.

What is the factor of a quadratic equation?Factor of a quadratic equation is any monomial or binomial which divides the quadratic equation without leaving any remainder.
What is factorization of quadratic equation?Factoring a quadratic equation can be defined as the process of breaking the equation into the product of its factors.
What is solution to the quadratic equation?The solutions of a quadratic equation represent the values of x that make the equation true. And the solutions to any equation are the x-intercepts of that equation.
According to the given question
We have a graph of a quadratic equation and x intercepts -1 and -5.
⇒ we have two points (-1,0) and (-5,0)
⇒ -1 and -5 will be the solution of the quadratic function.
⇒ x = -1 and x = -5
⇒ x+ 1= 0 and x + 5 = 0
or -x -1 = 0 and x+5 = 0
Therefore, the factors of the quadratic function whose graph is given are (-x -1) and ( x-5).

Answers
Answer:
22.5 m/h and 7.5 m/h
Step-by-step explanation:
Let's said that x is the speed of the faster car. That means the slower one must have the speed of x/3.
x/3 * 3 + 45 = x * 3
x + 45 = 3x
45 = 3x - x
45 = 2x
x = 22.5

For the graph of the function h(t) below determine h(153)
Answers
Answer:
1
Step-by-step explanation:
As can be seen, for h(t) where t is a multiple of 6, we get -6. Since 150 is a multiple of 6, 153 is 3 more and since the graph visually repeats every 6 units, we can see that h(t) when t is a (multiple of 6) + 3 = 1
Thus h(153)=1

Answer:
x = 9
Step-by-step explanation:
Given
5x - 31 = 23 - x ( add x to both sides )
6x - 31 = 23 ( add 31 to both sides )
6x = 54 ( divide both sides by 6 )
x = 9
Answer: X = 9
Step-by-step explanation: basically you solve it just like any other algebra equation. The only difference is that you have x’s on both sides. You have to move one of them over. I move the x to the right and I added it to the left side. 5x plus x is 6x. ( in case you didn’t already know an x never stands alone when you see one alone it always has an imaginary 1 beside it.) after I did that I tried to isolate 6x so I added 31 to 23. 31 plus 23 equals 54. I then had the equation 6x=54. The next thing I wanted to do was to isolate the x. I then dived 6 on both sides and got x= 9

12 = E + 2
E = 12 - 2
E = 10
Answer:
10
Step-by-step explanation:
There are 6 faces and 6 vertices.
The formula is F + V = E + 2.
So,
6 + 6 = E + 2
12 = E + 2
E + 2 = 12

By This - B+D+C = 130°-20°+E
Answer:
110 degrees
Step-by-step explanation:
when continuing line DC down to line AE, it creates a triangle with the intersection point at AE, C and E.
the angles in that triangle are
E (20 degrees)
the internal angle at C = 180 - 130 = 50 degrees
and the angle at the interception point at AE.
since CD is parallel to AB, that angle is equal to x.
the sum of all angles in a triangle is airways 180 degrees.
therefore this angle is
180 - 20 - 50 = 110 degrees = x
Solve for: X=____ Y=____
Round to the nearest tenth.
X= 60°
Y=30°
X=22.6°
Y=67.4°
X=30°
Y=60°
X=67.4°
Y=22.6°
Answers
Answer:
D
Step-by-step explanation:
These diagrams can drive you crazy. The only way you can do this question is to ASSUME that the angle that looks like it is 90 really is 90. That is a very dangerous assumption.
Solution for y
cos(y) = adjacent / hypotenuse
adjacent = 12
hypotenuse = 13
Cos(y) = 12 / 13
Cos(y) = 0.92308
y = cos-1 (0.92308)
y = 22.6
Solution for x
x does not need trig to solve.
x = 180 - 90 - 22.6
x = 67. 4
So that's D
