All of the equations contain -4 in their range.
A) -4 = sqrt(x) - 5
1 = sqrt(x)
x = 1; valid
B) -4 = sqrt(x) + 5
-9 = sqrt(x)
x = 81; valid
C) -4 = sqrt(x + 5)
16 = x + 5
x = 11; valid
D) -4 = sqrt(x - 5)
16 = x - 5
x = 21
I believe the equations contain square instead of square root, in which case the answer would be A because no other could have a negative range.

For option A: y = sqrt(x) - 5. Range is {f(x) | f(x) ≥ -5}

For option B: y = sqrt(x) + 5. Range is {f(x) | f(x) ≥ 5}

For option C: y = sqrt(x + 5). Range is {f(x) | f(x) ≥ 0}

For option D: y = sqrt(x - 5). Range is {f(x) | f(x) ≥ 0}

Can someone help me on this
Sidana [21]

Answer:

Area = 702.9 or 703

Step-by-step explanation:

By Pythagoras the. first, we need to find the base!

(H)2 = (P)2 + (B)2

(82)2 = (18)2 + b2

6724 = 324 + b2

b2 = 6724-324

b2 = 6100

b = √6100

b = 78.1

note - they all are in square

Now, area of the triangle:-

1/2 * b * h

1/2 * 78.1 * 18

= 702.9

Hope it helps!

Can someone help me please I’m struggling so much. let me know if the things that I put already are right
makvit [3.9K]

your calculations for volume (pi x r^2 × h) and surface area (2 × pi × r (h+r)) are correct. However your ratio are incorrect. From the formulas the ratio of surface area to volume would be r×h:2(h+r)
