Answer:
The area that she painted = 896 mm^2
Step-by-step explanation:
Given:
The given figure is a pyramid with square base.
Here we need to find the surface area of the figure that need to be painted.
Surface area of a square pyramid = (S×S) + 2×S×L square.units
Where, S = side of the base L = slant height of the pyramid.
Now we have to plug in the given values.
Here S = 14, L =25
Plug in these values into the formula
= (14*14) + 2*14*25
= 196 + 700
= 896 mm^2
The area that she painted = 896 mm^2
Hope this will helpful.
Thank you.
First we rewrite the expression correctly:
tn = ((-1) ^ n) * (n)
We now look for each of the terms:
t1 = ((-1) ^ 1) * (1) = - 1
t2 = ((-1) ^ 2) * (2) = 2
t3 = ((-1) ^ 3) * (3) = - 3
t4 = ((-1) ^ 4) * (4) = 4
The first four terms of the sequence are then:
-1, 2, -3, 4
Answer:
B.
-1, 2, -3, 4
Answer:
13
Step-by-step explanation:
Each row has 4 seats. The bus has 52 seats
52 divided by 4 =13
13 rows = answer
Answer:
Slope is - 4.
Step-by-step explanation:
The given points are (-1,10), (1,2), (3,-6) and (5,-14).
Now, we have to find the slope of the line containing these points.
We can pick any two points to find the slope. Let they are (-1,10) and (1,2).
Now, we know that the slope of a straight line passing through any two known points and is given by
........... (1)
Therefore, the slope of the straight line through the given points will be
{From equation (1)} (Answer)
Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - x ← is in slope- intercept form
with slope m = -
