Answer:
function A
Step-by-step explanation:
First, we need to find the function of A. USing the coordinate points (0, 10) and (2,8)
Since y = mx+c
m = y2-y2/x2-x1
m = 8-10/2-0
m = -2/2
m = -1
From the coordinate (0, 10), the y-intercept is 10 i.e c = 10
The required equation is y = -x + 10
x intercept occurs at where y = 0
0 = -x+10
x =10
Hence the x-intercept of function A is 10
For Function B y = -2x^2 + 1
when y = 0
0 = -2x^2 + 1
2x^2 = 1
x^2 = 1/2
x = 1/√2
Hence the x intercept is 1/√2
Hence the function that has a greater y-intercept is function A

how do I solve −2x−9≥5 to get x
Answer:
x = - 7
Step-by-step explanation:
- 2x = 5 + 9
- 2x = 14
x = - 14 / 2
x = - 7
Hope this answer helps you :)
Have a great day
Mark brainliest
Answer:
x ≤ -7
Step-by-step explanation:
−2x−9 ≥ 5
add 9 to both sides
-2x -9 +9 ≥ 5+9
-2x ≥ 14
divide -2 on both sides
since we're dividing by a negative number we need to flip our inequality sign
-2x/-2 ≥ 14/-2
x ≤ -7
Consider a radioactive substance with original weight 20grams given by W(x)= 20 x (0.95)^x, where W(x) is with weight after x years. In about how many years is the radioactive substance half of its original weight? Type answer to one decimal place.
Answer:
13.5 years
Step-by-step explanation:
We are given the expression:
W(x)= 20 x (0.95)^x
Where W(x) = 20grams/2
= 10 grams
Hence:
10 = 20 x (0.95)^x
Divide both sides by 20
10/20 = 20 x (0.95)^x/20
0.5 = (0.95)^x
Take the log of both sides
log 0.5 = log (0.95)^x
log 0.5 = x log (0.95)
Divide both sides by log 0.95
x = log 0.5 / log 0.95
x = 13.513407334 years
Approximately to 1 decimal place =✓13.5 years
Therefore, it will take 13.5 years for the radioactive substance to be half of its original weight.

Step-by-step explanation:
A company makes fish tanks in the shape of right rectangular prisms. The company has an order for a fish tank that must be exactly 4 feet long and hold at least 35 cubic feet of water. The company wants to save money on materials and will make the tank with the smallest surface area possible. The dimensions of the tank must be in whole foot increments and a top is included in the construction What dimensions for the width and height of the fish tank will satisfy the requirements
The dimensions for the width and height of the fish tank will be 4 feet and 2 feet .
What is dimension?Dimension is the measurable extent of a particular kind, such as length, breadth, depth, or height.
According to the given problem,
let , b = is the width of the fish tank
h = is the height of the fish tank given that , hold at least 35 cubic feet of water .
so ,
4×b×h ≥ 35
⇒ h ≥ 35/4b
now , surface area of the fish tank
⇒ 4b + 2× 4h + 2× bh
now substitute the value of h
here
⇒ ≥ 4b +70/b + 35/2
⇒ ≥ 40(70)^1/2 + 35/2 (if and only if b= (70)^1/2 / 2 , the equal sign holds )
therefore ,
= (70)^1/2 / 2 b ≈ 4.18 so b is 4 . when b = 4 ,
h = 35 / 4 × 4 = 2.1875 round off h = 2
so , the minimum surface area of fish tank is
⇒ 4×4+ 2× 4×2 + 2× 4×2⇒ 48
hence , the height and the width of the fish tank is 2 and 4 .
