Answer:
Slope = 2, and y intercept = -5
Answer:
The overall equation for slope-intercept is
y = mx + b
M would equal slope
B would be equal y-intercept.
So, judging from both equations now,
-2 is slope, while y-intercept is -5
If you are confused on why the y-intercept is -5 I will answer it for you. Have a good day ^-^

You have $3,000 in savings account that pays 2.5% interest, compounded monthly. What is future value in 4 years?
Answer:
[tex]\$4453.52[/tex]
Step-by-step explanation:
Principal amount (P) = $3,000
Rate of interest (R) = 2.5%
Time period (T) = 4 years
Future value in 4 years = [tex]P(1+\frac{R}{100})^{4T}[/tex]
Put [tex]P=3000\,,\,R=2.5\,,\,T=4[/tex]
Therefore,
Future value in 4 years = [tex]3000(1+\frac{2.5}{100})^{4(4)}=3000(1.025)^{16}=\$4453.52[/tex]

The direct distance from a starting point to a finish line is 15 miles. Unfortunately, you can't take the direct route. If you travel 12 miles east, how many miles north must you travel to reach the finish line? 10 19 9
Answer:
9 miles
Step-by-step explanation:
From Pythagoras :
Opposite^2 = Hypotenus^2 - Adjacent^2
The direct route = 15 miles = hypotenus
x² = 15^2 - 12^2
x² = 225 - 144
x² = 81
x =. Sqrt(81)
x = 9
Hence, you must travel 9 miles north
Answer:
9 miles :)
Step-by-step explanation:
a^2 + 12^2 = 15^2
a^2 + 144 = 225
a^2 = 81
a = 9

Describe how a root can be written using a rational exponent. Give an example.
Answer:
sqrt(x)=x^1/2
Step-by-step explanation:
The root of a number is the same as writing that number to 1 over the root. In a square root, it is what number multiplied by itself (x*x), as you can see there are two, so it is that number to the 1/2 power. another example is something to the seventh power. that is calculating what number multiplied by itself 7 times would equal the nmber you are taking the root of. (x*x*x*x*x*x*x) so this would be a number to the 1/7 power.

Josh and his family are taking a family vacation. They travel 340 miles in 5 hours before stopping at a rest stop.
How far did the family get in 3 1/2 hours?
Answer:
238 miles
Step-by-step explanation:
340 miles = 5 hours
So get 1 hour by dividing by 5 on both sides
5/5 = 1 hr
340/5 = 68
So in 1 hour they travel 68 miles
You want to find 3 1/2 hours
Do 68 x 3 to get 3 hours
So it would be 68 x 3 =204
Plus the half an hour - which you get by doing 68/2 = 34
68 = 1 hour, so half of that must be half an hour
So to get the final distance you do 204 (3 hours) +34 (half an hour)
204 + 34 =238
how many sides are there?
Answer:
13
Step-by-step explanation:

A convex polygon has 13 sides when the interior angle sum is [tex]1980^{0}[/tex].
What is convex polygon?A polygon is called a convex polygon when no line segments between the points, goes inside. The boundaries of the convex polygon do not go inside and all the vertices are pointed outside away from the center. The interior angles of a convex polygon are less than 180°.
Given a convex polygon
For a convex polygon with n sides, the interior angle sum is [tex]180^{0}[/tex] × [tex](n-2)[/tex]
Let [tex]180^{0}[/tex] × [tex](n-2)[/tex] = [tex]1980^{0}[/tex]
⇒ n - 2 = 11
⇒ n = 11 + 2
⇒ n = 13
Thus, a convex polygon has 13 sides when the interior angle sum is [tex]1980^{0}[/tex].

In ΔMNO, the measure of ∠O=90°, the measure of ∠N=70°, and OM = 3.3 feet. Find the length of MN to the nearest tenth of a foot.
Answer:
Side MN = 3.5
Step-by-step explanation:
Side NO = 1.2011
Side OM = 3.3
Side MN = 3.51179
Angle ∠M = 20° = 0.34907 rad = π/9
Angle ∠N = 70° = 1.22173 rad = 7/18π
Angle ∠O = 90° = 1.5708 rad = π/2
A certain brand of shampoo contains 12 ounces in a bottle. The company
decides to redesign the shape of the shampoo bottle. The new type of
bottle contains 15 ounces of shampoo. What is the percent of increase in
the amount of shampoo the new bottle contains?
Answer: 15% I think
Step-by-step explanation:
The percent of increase in the amount of shampoo the new bottle contains is 25%.
Given that, a certain brand of shampoo contains 12 ounces in a bottle and the new type of bottle contains 15 ounces of shampoo.
What is the percentage of increase?Percentage increase is the difference between the final value and the initial value, expressed in the form of a percentage.
Percentage increase = (Final value - Initial value) / Initial value × 100
Now, initial value = 12 and final value = 15
Percentage increase = (15-12)/12 × 100
= 3/12 × 100
= 1/4 × 100
=25%
Therefore, the percent of increase in the amount of shampoo the new bottle contains is 25%.

For what value of k is the expression x^4 + kx^2 + 49 a perfect square?
Answer:

Step-by-step explanation:
Completing the square gives
[tex]x^4 + kx^2 + 49\\= (x^2+7)^2 - 14x^2 + kx^2[/tex]
So we have to cancel the latter two terms out for the expression to always become a square (otherwise we are dealing with a square plus something else, which doesn't always result in a square), giving us our answer directly.
