Answer:
Step-by-step explanation:
As we move from the x-intercept (-2, 0) to the y-intercept (0, 4), x increases by 2 (this is the run) and y by 4 (this is the rise). Thus, the slope of this line is
m = rise/run = 4/2 = 2.
Given the y-intercept (0, 4) and the slope (2), the slope-intercept form of the equation of this line is y = 2x + 4.
From this we get the point-slope form:
y = 2x + 4 becomes y - 4 = 2(x - 0), or just y - 4 = 2x.
Answer: 3/10
Step-by-step explanation:
3/10 + 4/10= 7/10
10/10 - 7/10= 3/10

and 


r = 7 units
The surface is a cylindrical surface with radius 7 units
Answer: Choice B 
=============================================
Explanation:
The endpoint is at 4.5 and this endpoint is a filled in circle. So we'll have "or equal to" as part of the inequality sign. This is because we are including the endpoint as part of the shaded solution region.
The other part of the inequality sign is "less than" because the shading is to the left of the endpoint. Any point in the shaded region is less than 4.5, or it could be equal to 4.5
Put another way: x is either 4.5 or smaller
We write that as
which is read out as "x is less than or equal to 4.5"
Surrounding this in curly braces tells the reader we're dealing with a set of values. The first part "x |" means "x such that"
All together we end up with the answer
which translates to "x such that x is less than or equal to 4.5"
We know that 1 ft = 12 in.
The dimensions of the trunk of a car:
4 ft = 48 in wide, 3 ft = 36 in deep, 2 ft = 24 in tall.
V = 48 * 36 * 24 = 41,472 in³
41,472 in³ ≈ 4 * 10^4 in³
And the volume of the calculator:
V ( calc. ) = 3 * 4 * 12 = 144 in³
Answer:
Desi`s error is D ) The volume of the calculator is not about 60 in³.
