\sf y=mx+b

m is the slope
b is the y-intercept

so that means that the y-intercept of

\sf y=3.5x + .4

is \sf .4

Y-intercept is value of y when x=0.
So just plug in x=0 and solve for y;
 
y = 3.5x - 0.4
y = 3.5(0) - 0.4
y = 0-0.4
y = -0.4
   
So y-intercept is -0.4

Consider the integral 8 (x2+1) dx 0 (a) Estimate the area under the curve using a left-hand sum with n = 4. Is this sum an overe
Elina [12.6K]

Answer:

  (a) 120 square units, underestimate

  (b) 248 square units, overestimate

Step-by-step explanation:

(a) <u>left sum</u>

The left sum is the sum of the areas of the rectangles whose width is the total interval width (8-0) divided by the number of divisions (n=4). The height of each rectangle is the function value at its left edge.

We can compute the sum by adding the function values and multiplying that total by the width of the rectangles:

  left sum = (1 + 5 + 17 + 37)×2 = 60×2 = 120 . . . square units

The curve is increasing throughout the interval of interest, so the left sum underestimates the area under the curve.

__

(b) <u>right sum</u>

The rectangles whose area is the right sum are shown in the attachment, along with the table of function values. The right sum is computed the same way as the left sum, but using the function value on the right side of each subinterval.

  right sum = (5 + 17 + 37 + 65)×2 = 124×2 = 248 . . . square units

The curve is increasing throughout the interval of interest, so the right sum overestimates the area under the curve.

_____

The actual area under the curve on the interval [0, 8] is 178 2/3, just slightly less than the average of the left- and right- sums.

Which of the following is an arithmetic sequence?
masha68 [24]

Answer:

B

Step-by-step explanation:

And arithmetic sequence is a sequence in which the difference between each of the numbers are constant.

It is not A, because the difference between 3 and 9 is positive 6, and the difference between 9 and 81 is positive 72.

It is not C, because the difference between 4 and 1 is -3, and the difference between 1 and 4 is positive 3.

It is not D, because the difference between 2 and -2 is -4, and the difference between -2 and 2 is positive 4.

And it is B because the numbers maintain a constant difference between each other, which is -3.

Nathan is building a toolshed with a rectangular floor. The area of a rectangle is given by the formula l⋅w, where l represents
Pachacha [2.7K]

Answer:

Here, l is the length of the rectangle and w is the width of the rectangle

To Compare the values, you must calculate each given situation.

Area of a rectangle is equal to  length times width.

i.e, A = l \times w

(A)

if l = 8 units and w= 6 units,

then;

A = l \times w = 8 \times 6 = 48 unit^2

(B)

if l =7 units  and w = 7 units

A = l \times w = 7 \times 7 = 49 unit^2  

Therefore, the Part B would yield a larger area.

If l -7 units and w = 7 units , the area of larger floor is 49 square units.

Factor.<br> 28 - 4u<br> I don’t know how to factor 28-4u so if anyone can help thank you
Sedaia [141]

Answer: 4(7-u)

Step-by-step explanation:

In order to factor, you have to find the GCF (Greatest Common Factor)

28:1, 28, 2, 14, 4, 7

4:1, 4, 2

The greatest common factor here is 4.

You can factor out 4 from this equation, therefore making it 4(7-u)
