Explain how to and find the area of one triangular face
Answer:
Well its the same formula for the area of a triangle, nothing changes.
a=B*H/2
Step-by-step explanation:
Even if the shape changes, in order to find the area of one side of a triangle, locate the base and height and multiply those two together. After that, use that product and divide it by 2 to find the area of that triangle.

Is 2 a solution of 4x + 12= 4? Complete the statement. The equation is (true, false) when x = 2, so 2 (is, is not) a solution. WILL MARK BRAINLIEST
Answer:
The answer is false and is not
Explanation:
Given the equation - [tex]4x+12=4[/tex]
Substitute x = 2 in the equation
[tex]4(2)+12=4\\8+12=4\\20=4[/tex]
Thus, the equation is false. When the equation is false, meaning that the coordinate x-term isn't passed by the line. (Rather say that the point is not the part of the graph.)
The equation is false is our first answer.
If the equation is false, that means the given value is not part of the graph, thus making the x-value not the solution.
Answer:
The equation is FALSE when x=2, so 2 IS NOT a solution.
how many solutions does the quadratic have? 2x^2+3x-5
Answer:
2 solutions
Step-by-step explanation:
Given
2x² + 3x - 5 ( to solve the quadratic equate it to zero )
2x² + 3x - 5 = 0 ← in standard form
(2x + 5)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
2x + 5 = 0 ⇒ 2x = - 5 ⇒ x = - [tex]\frac{5}{2}[/tex]
x - 1 = 0 ⇒ x = 1
The 2 solutions are x = - [tex]\frac{5}{2}[/tex] , x = 1

sin^2a-sin^2b=cos^2b-cos^2a
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
sin²x + cos²x = 1 , then sin²x = 1 - cos²x
Consider the left side
sin²a - sin²b
= (1 - cos²a) - (1 - cos²b)
= 1 - cos²a - 1 + cos²b
= cos²b - cos²a
= right side , thus verified
The sum of the angle measures a polygon with n sides is 720. What is n?
The polygon has 6 sides.
What is a polygon?
'A polygon, in geometry is any closed curve consisting of a set of line segments (sides) connected such that no two segments cross.'
According to the given problem,
Sum of measures of angle = 720
We know,
Sum of interior angles of polygon = 180( n - 2 )
Where, n = number of sides.
⇒ 180( n - 2 ) = 720
⇒ n - 2 = 720/180
⇒ n - 2 = 4
⇒ n = 6
Hence, we can conclude that the polygon has 6 sides.

Step-by-step explanation:
This is a geometric progression and the formula to use to find the nth term will be: = ar^(n-1)
where,
a = 3
r = -9/3 = -3
n = 20
Therefore, ar^(n-1)

A polynominal function that describes an enclosure is v(x)=1500x_x2 where x is the length of the fence in feet what is the maximum area of the enclosure
Answer:
The answer is below
Step-by-step explanation:
A polynominal function that describes an enclosure is v(x)=1500x-x2 where x is the length of the fence in feet what is the maximum area of the enclosure
Solution:
The maximum area of the enclosure is gotten when the differential with respect to x of the enclosure function is equal to zero. That is:
V'(x) = 0
V(x) = x(1500 - x) = length * breadth.
This means the enclosure has a length of x and a width of 1500 - x
Given that:
v(x)=1500x-x². Hence:
V'(x) = 1500 -2x
V'(x) = 0
1500 -2x = 0
2x = 1500
x = 1500 / 2
x = 750 feet
The maximum area = 1500(750) - 750² = 562500
The maximum area = 562500 feet²
Answer:
562500 feet²

When will Peter's baseball hit the ground? Use mathematical evidence to explain your answer.
Question:
The height of Peter’s baseball is given by the graph below (See attachment)
When will Peter’s baseball reach the highest height? What is the height? When will Peter’s baseball hit the ground? Use mathematical evidence to explain your answer.
Answer:
Peter's baseball reached the maximum height at 1.5 secondsPeter's baseball hit the ground at 4 secondsStep-by-step explanation:
The (a) & (b) will be answered by making reference to the attachment.
Solving (a): Time to reach maximum height
The height is plotted at the vertical axis while the time taken is at the horizontal axis.
From the attachment; the following details can be observed
The maximum height is at 90ftWhen the maximum height is traced to the horizontal axis, the corresponding time is 1.5sUsing function notations, this can be represented as:
[tex]f(1.5) = 90[/tex]
And the interpretation is that:
Peter's baseball reached the maximum height at 1.5 seconds
Solving (b): Time to hit the ground
The interpretation of this question is to solve for the x intercept of the graph.
From the attachment; the following details can be observed
The ground is at 0 feetThe corresponding time at 0 feet is 4sUsing function notations, this can be represented as:
[tex]f(4) = 0[/tex]
And the interpretation is that:
Peter's baseball hit the ground at 4 seconds

what is the equation of the line
Answer:
y=-x+3.
Step-by-step explanation:
The graph goes down one and right one before making another point. This means that the slope is -1/1. Simplify and you get -1. So far we have y=-1x. -1x is the same as -1. Now we have y=-x. The graph intersects the y-axis at the point (0,3). This makes our y-intercept 3. Our final equation is y=-x+3.
Y-4=3(x - 1)

a graph passes through the points (0,2),(1,3), and (2,4). Does this graph represent a linear function or a non linear function?
9514 1404 393
Answer:
linear
Step-by-step explanation:
The slope of the line between the first pair of points is ...
m = (y2 -y1)/(x2 -x1)
m = (3 -2)/(1 -0) = 1/1 = 1
The slope of the line between the second pair of points is ...
m = (4 -3)/(2 -1) = 1/1 = 1
The slopes are the same, so the points are on the same line. The graph is that of a linear function.
EF is the midsegment of trapezoid ABCD. Determine the value of x. 12.6 F E
The value of x is 5, the correct option is B
What is a Trapezoid?A quadrilateral with one side parallel to the other is a Trapezoid.
The midline in a trapezoid is parallel to its bases and the length is equal to half the sum of the bases.
In the figure attached the length of one of the parallel sides and the midline is given, the other base length has to be determined.
The length of AB = 12.6
The length of the midline EF = 8.8
The value of x =?
From the definition,
8.8 = (12.6 + x) /2
8.8 * 2 = 12.6 +x
