(-2×7)³=8×7³
Answers
Answer:
Step-by-step explanation:
Remarks
The answer given is pretty close to being correct. The 8 is correct -- that is 2^3 power.
The problem is in the minus sign. Think of it as (-1)^3
(-1)^3 = -1 * -1 * -1.
There are 3 minuses there. 2 of them will make plus 1. The third one will change the result to - 1.
Answer: 8 should be -8
Given the line y=3/5x+2 find the perpendicular line passing through the point (12,-7)
Answers
Answer:
y=-5/3x+13.
Step-by-step explanation:
As a line that is perpendicular to anoher line has a slope that is the negative reciprocal of the line's original slope, we know that the slope of our new line is -5/3. As it passes point (12, -7), we can use the point slope formula which is y-y1=m(x-x1). So plug in, y+7=-5/3(x-12) and that gives us y+7=-5/3x+20 which gives our final answer of y=-5/3x+13.
How do you solve for 4, 5, or 6?

Answer:
see images
Step-by-step explanation:
For all of these questions it helps to know the special right triangle, the 30°-60°-90° triangle. There is a special shortcut to find the sides of the 30°-60°-90° triangle.
For question4 and 5, these are equilateral triangles so the angles are all 60° So if you drop the height, it makes two 30°-60°-90° triangles. ***The short leg is HALF the hypotenuse or the hypotenuse is DOUBLE the short leg. The long leg is the short leg × sqroot3.***
This shortcut, special rt triangle info is used in all three of your questions. See image. Then you will have base and height or the apothem and side length for the Apothem Area formula:
A = 1/2 a•s•n
where a is the apothem, s is the side length and n is the number of sides. It looked like you already used this formula. See image.

Answers
Answer:
B. y = -x – 1
Step-by-step explanation:
calculate slope =
y2-y1 = -5- (-2) = -3
x2-x1 = 4 - 1 = 3
m (slope) = -3/3 = -1
using points (1,-2) for calculating y-intercept:
y = mx + b
-2 = -1(1) + b
-2 = -1 + b
-1 = b
b = -1
answer is B y= -x - 1

Are the two cones congruent? explain and include details to support your claim.
Answers
The two cones are not congruent because one of the cones is oblique in nature.
What are congruent shapes?Congruent shapes are identical in size and shape. To put it another way, if you hold an object or element in a mirror, the picture you get is congruent to the object.
However, two figures may seem to be identical, but one side or angle in one figure may deviate significantly from the other. The easiest technique to assess sides and angles to check if they are equivalent or congruent is to use markings on figures.
When we apply that technique to the two figures, we realized that the two cones are not congruent because one of the cones is oblique in nature, this resulted in a difference in the slant height of the cones.

What is the shape of the cross section of the figure that is parallel to the rectangular base?
A. a parallelogram that is not a rectangle
B. a rectangle
C. a triangle that must have same dimensions as one of the faces
D. a triangle that does not have the same dimensions as one of the faces
Answers
Answer:
B. a rectangle
Step-by-step explanation:
A cross section is the new face you see when you slice through a 3D figure. So if you slice a rectangular pyramid parallel to the base, you get a smaller rectangle as the cross section. Similarly, if you slice parallel to a triangular base then your cross section will be a triangle.
Hope this helps and God bless!
Step-by-step explanation:
I think Its D because In the rectangular base its not equal sides like a square so it would be more be like sides that are not perpendicular.

this question isn't quite clear, is the diagram of the triangle necessary for me to answer this question ?
Step-by-step explanation:
but by simple analysis,
since the "unknown" is b
option (a) which is 42 + b2 = 52 is the best equation.
because we are looking for the value of "b", therefore there should be letter "b" in equation we're going to use. hope you understand...

Answers
Answer: a+51=90, a+51+90=180, 39
Step-by-step explanation:
a+51=90 works because the angles add to form a right angle.
a+51=180 does not work because the angles add to form a right angle, not a straight angle.
a+51+90=180 works because all those angles add to form a straight angle.
a+90=180 does not work because the unknown in this situation refers to a+51, not just a.
Solving the equation, we get a=39, so 39 is also an answer.
