The choices are in the slope-intecept form: y = mx + b, where m is the slope and b is the y-intercept. Looking at the graph, the y-intercept is the point at which it intersects the y-axis. That would be -1. So, the answer is either the 1st or 2nd choice. Next, we find the slope. Take 2 points that lie along the line. For example, points (1,2) and (2,5). Calculate for the slope.

m = (y2-y1)/(x2-x1)
m = (5-2)/(2-1)
m = 3

Hence, the graph is y = 3x - 1

i. Let t be the line tangent at point J. We know that a tangent line at a point on a circle, is perpendicular to the diameter comprising that certain point. So t is perpendicular to JL
let l be the tangent line through L. Then l is perpendicular to JL ii. So t and l are 2 different lines, both perpendicular to line JL.
2 lines perpendicular to a third line, are parallel to each other, so the tangents t and l are parallel to each other.

What percent is the change in the price if: a The price was $100 and now it is $1250?

KatRina [158]

Answer:

The increase is 1150.

11.5 times the original value, or 1150% of it. That's a big increase, and I would not buy that thing, whatever it is.

Suppose your new business made a profit during the first year of $3000. If the profit increased 12% per year, find the total of

mariarad [96]

Answer:

Therefore the total of all profit earned by the end of of the the first 5 years is $19,058.542.

Step-by-step explanation:

To find total profit earned per year, we need to use the compound growth formula.

The compound growth formula:

$A= P(1+r)^t$

A= Amount after t years

P= initial amount

r= rate of growth

t= time in year.

Given that,

New business made a profit during the first year of $3000.

If the profit increased 12% per year.

Here P= $3,000 and r =12%=0.12 , t=1 years

Plugging all value in the above formula:

$A=3000(1+0.12)^1$

=3000(1.12)

=$3360

Profit after 2 year is $3,360.

Now, P= $3,000 and r =12%=0.12 , t=3 years

$A=3000(1+0.12)^2$

=3000(1.12)²

=$3763.2

Similar the profit at 4 year is

$A=3000(1+0.12)^3$

=3000(1.12)³

=$4214.784

The profit at 5th year is

$A=3000(1+0.12)^4$

=3000(1.12)⁴

=$4720.558

Therefore the total of all profit earned by the end of of the the first 5 years is=$(3,000+3360+3763.2+4214.784+4720.558)

=$19,058.542

Abbys mother is making treat bags for the 30 students in abbys class. She purchased bags at 5 for 1 candy bars at 10 for 0.50 an

Stella [2.4K]

Answer:

Abby's mother spent $9.75 for the classroom not including tax.

Step-by-step explanation:

Know:

5 bags for 1 dollar

10 candy bars for 50 cents

3 whistles for 75 cents

5×6=30

10×3=30

3×10=30

5 times 6 is thirty. So find the product of 6 and 1 which is 6. 6 is the overall cost of bags.
10 times 3 is 30. So find the product of 3 and .50 which is 1.50. 1.50 dollars is the overall cost of candy bars.
3 times 10 is 30. You then find the product of 3 and .75. The product of this is 2.25 which is the total cost of whistles.
Next you add all the values together which are 6.00 + 1.50 + 2.25 this equals $9.75
