How to calculate the surface area of a regular pyramid?To calculate the surface area of a regular pyramid, the formula given below is used;
Surface area of pyramid = SA = A + 3(1/2bh) = A + 3/2bh,
Where A = area of triangle = ½bh
b = base = 5 in
h = slant height = 13. in
SA = ½× 2.5×4.3 + 3/2×5 ×13
= 5.375 + 97.5
= 102.9 in²

I feel there is important information lost in the way you provided the problem statement.
e.g. "... also equal to ?"
equal to what ?
sin x = what ?
so, I can only guess some things.
answer C is definitely correct for any angle up to 180 degrees.
answer A is only correct for an angle of 45 or 225 degrees, where sin(x) and cos(x) are both 1/sqrt(2) or both -1/sqrt(2).
answer B is always wrong (459 degrees is no special number, this is a full circle of 360 degrees and then additional 99 degrees there is no special relationship between sine and cosine for 99 degrees, so sine and cosine cannot have the same value for any x).
answer D is always wrong, as there is always a 30 degree difference between the arguments for sine and cosine, and that can never lead to an equal value.
answer E is also always wrong, as these 45 degrees difference also block equal values.

Given:
Two figures.
To find:
The area of the shaded regions for both figures.
Solution:
In first figure, the shaded area is a triangle with base 15 units and height 12 units. So, the area of the shaded region is equal to area of the triangle.
[tex]A=\dfrac{1}{2}\times base\times height[/tex]
[tex]A=\dfrac{1}{2}\times 15\times 12[/tex]
[tex]A=\dfrac{180}{2}[/tex]
[tex]A=90[/tex]
Therefore, the area of the shaded region is 90 square units.
In the seconds figure, we need to subtract the area of square from the area of triangle, to get the area of the shaded region.
Area of triangle with base 15 and height 18 is:
[tex]A_1=\dfrac{1}{2}\times 15\times 18[/tex]
[tex]A_1=\dfrac{270}{2}[/tex]
[tex]A_1=135[/tex]
Area of the square with sides 6.
[tex]A_2=(side)^2[/tex]
[tex]A_2=(6)^2[/tex]
[tex]A_2=36[/tex]
Now, the area of the shaded region is:
[tex]A=A_1-A_2[/tex]
[tex]A=135-36[/tex]
[tex]A=99[/tex]
Therefore, the area of the shaded region is 99 square units.
17. Find the volume of the figure below. 3 mm 9.7 mm 7.2 mm
Answers
Answer:
70.2
Step-by-step explanation:
The volume of the given figure will be 104.76 mm³. Volume is the product of the area of the length/height.
What is volume?
The term “volume” refers to the amount of three-dimensional space taken up by an item or a closed surface. It is denoted by V and its SI unit is in cubic cm.
The volume of the given figure is;
Volume=Area×Length
Area=(1/2)×9.7×7.2
Area=34.92 mm²
Volume=Area×Length
Volume=34.92×3
Volume=104.76 mm³
Hence,the volume of the given figure will be 104.76 mm³.

Answer:
y=x+3
Step-by-step explanation:
when you connect all the dots it makes a straight linear line. then you can use the format y=mx+b
y is the y value
m is the slope (change in y divided by change in x or, rise over run)
x is the x value
b is the y intercept (the y value where the line will touch the y axis/vertical line)
to make the equation
y=mx+b
y and x are variables so you dont need to write them
the slope is rise/run just pick two points such as the first point (0,3) and the second point (1,4)
between these points it changes one unit to the right (1) and one unit up vertically meaning 1/1
=1
when the slope is 1 you get
y=1x+b which is just y=x+b
then the y intercept
the first dot is touching the y axis line and it's y value is 3
y=x+3

(Quadratic Regressions)
A rocket is shot off from a launcher. The accompanying table represents the height of
the rocket at given times, where x is time, in seconds, and y is height, in feet. Write a
quadratic regression equation for this set of data, rounding all coefficients to the
nearest hundredth. Using this equation, find the height, to the nearest foot, at a time
of 6.4 seconds.
Answers
Answer:
y = - 15.57x² + 179.32x + 0.20
510
Step-by-step explanation:
The quadratic model obtained using a quadratic regression solver with Coefficient rounded to the nearest hundredth is :
y = - 15.57x² + 179.32x + 0.20
Where, height = y
x = time
Using the model obtained ; the height, to the nearest foot, at a time, x = 6.4 seconds.
y = - 15.57x² + 179.32x + 0.20
y = - 15.57(6.4^2) + 179.32(6.4) + 0.20
y = 510.1008
y = 510
The quadratic model obtained using a quadratic regression solver with Coefficient rounded to the nearest hundredth is :
y = - 15.57x² + 179.32x + 0.20height = y
x = time
Using the model obtained;
The height, to the nearest foot, at a time, x = 6.4 seconds.
y = - 15.57x² + 179.32x + 0.20 y = - 15.57(6.4^2) + 179.32(6.4) + 0.20 y = 510.1008 y = 510Thus, the correct answer is 510.
