Answer:
it could be 1. c 2. a 3. d 4. b
or it could be the answers i did for last time in the pic: (that is my old account that got banned)
but i think the answers that are right are the ones i did rn of 1. c 2. a 3. d 4. b

Step-by-step explanation:
Given:
- The slant length 10 units
- A right square pyramid with base edges of length 8
Now we use Pythagoras to get the slant height in the middle of each triangle:
=
=
units
One again, you can use Pythagoras again to get the perpendicular height of the entire pyramid.
=
= 6 units.
Because slant edges of length 10 units each is cut by a plane that is parallel to its base and 3 units above its base. So we have the other dementions of the small right square pyramid:
- The height 3 units
- A right square pyramid with base edges of length 4
So the volume of it is:
V = 1/3 *3* 4
= 32
Answer:
Step-by-step explanation:
Slope intercept form is a way of modeling a quadratic equation, where the coefficient of the term () is the slope (change) of the line, and the constant is the y-intercept. In essence;(
), where (
) is the slope and (
) is the y-intercept.
The slope of the given line is () because, this is the rate at which the candle burns, therefore, it is the change in the line. The change is (
) because this is the rate of burning, the slope is also negative since the height is decreasing. (
) is the y-intercept because it is the starting height of the candle. One will take the time since the start of burning the candle, multiply it by the slope, and add it to the y-intercept to find the current height of the candle. Therefore, the equation is (
), where the output (
) is the current height of the candle, and the input (
) is the time at which the measruement was taken.
