Answer:
Step-by-step explanation:
we know that
The equation of a exponential growth is equal to
where
a is the initial value
r is the rate of growth
x is the time in hours
y is the value of the quantity
we have
substitute
For x=22 hours
substitute
X2+7x-8=0
product=-8 times 1 = -8
sum= 7
{-1, 8}
x2-1x+8x-8=0
x(x-1)+8(x-1)=0
x+8=0 or X-1=0
x=-8
Answer:
median is 75 and range is 45
Step-by-step explanation:
range is largest number - smallest number so 95-50=45
Median is the medium of all the data. The medium is shown by the middle line in the box portion of the plot.
To find the surface area you will need to find the area of all 5 surfaces (faces) on the prism. On a triangular prism there are 2 triangular faces and 3 rectangular faces. All 3 rectangular faces are the same and the 2 triangular faces are also the same.
To find the area of the triangular faces, you will use the formula for finding the area of a triangle:
A = 1/2bh
1/2 x 10 x 8.7
A = 43.5 in^2
To find the area of the rectangular faces, you will use the formula for finding the area of a rectangle:
A = bh
10 x 3
A = 30 in ^2
30 + 30 + 30 + 43.5 + 43.5 = 177
The minimum amount of wrapping paper needed for the gift is 177 square inches.
