A package of 8 hot dogs is on sale for $4.00. What is the price per hot dog?
each hot dog is 50 cents. Because .50+.50+.50+.50+.50+.50+.50.50=4 We know each hot dog is worth .50 cents because a pack of 8 HD cost $4 so each HD would need to cost less that a dollar. hope this helps!
Find the surface area of a cylinder with a base radius of 4 cm and a height of 7 cm.
Use the value 3.14 for a, and do not do any rounding.
Be sure to include the correct unit.
Answer: 276.32cm³
Step-by-step explanation:
Surface area, A, of a cylinder is given by the formula:
A = 2*pi*r*h + 2*pi*r²
r = radius
h = height
Substituting pi for 3.14 gives:
A = (2 * 3.14 * 4 * 7) + (2 * 3.14 * 4²)
A = 276.32cm³

The map shows a linear section of Highway 35. Today, the Ybarras plan to drive the 360 miles from
Springfield to Junction City. They will stop for lunch in Roseburg, which is at the midpoint of the trip. If they
have already traveled 55 miles this morning, how much farther must they travel before they stop for lunch?
a. 125 mi
b. 145 mi
c. 180 mi
d. 305
They must travel 125 miles farther before they stop for lunch and option A is the correct answer.
We have,
The total distance of the trip is 360 miles.
They plan to stop for lunch at the midpoint of the trip, which is
360 / 2 = 180 miles.
Now,
They have already travelled 55 miles this morning.
To find out how much farther they must travel before stopping for lunch, we subtract the distance travelled from the midpoint:
180 - 55
= 125 miles.
Thus,
They must travel A. 125 miles farther before they stop for lunch.

Jennifer pays $12.50 a month for Amazon Prime and pays extra every time she rents a movie. One month she rented 1 movie and paid $17.75. Another month she paid $49.25 and rented 7 movies.
Answer: y=5.25x+12.50
Step-by-step explanation:
The original 12.50 is how much she pays each month regardless of rented movies, it is the 0 value and doesn't change. Each rented movie costs 5.25 (17.75-12.50=5.25) and that value would be multiplied by the amount of movies she rents that month, and then added onto the original base value.

Answer:
a) 4 to the 14th power
b) 12 to the 9th power
c) 5 to the 7th power
d) 7 to the 3rd power
Step-by-step explanation:
a) [tex]4^{6}[/tex] · [tex]4^{8}[/tex] equals 4 to the 14th power.
Using the Product Rule of Exponents:
[tex]a^{m} a^{n} = a^{m+n}[/tex]
You could add the exponents since they have the same base.
b) [tex]12^{6}[/tex] · [tex]12^{3}[/tex] equals 12 to the 9th power.
Same Product Rule applies as we did in problem a).
c) [tex]\frac{5^{10} }{5^{3} }[/tex] equals 5 to the 7th power.
Using the Quotient Rule of Exponents:
[tex]\frac{a^{m} }{a^{n} } = a^{m - n}[/tex]
You'll have to subtract the exponents since they have the same base.
[tex]\frac{5^{10} }{5^{3} } = 5^{10 - 3} = 5^{7}[/tex]
d) [tex]\frac{7^{6} }{7^{3} }[/tex] equals 7 to the 3rd power.
Same Quotient Rule applies as we did in problem c).
[tex]\frac{7^{6} }{7^{3} } = 7^{6 - 3} = 7^{3}[/tex]

Answer:
Step-by-step explanation:
a) Sum = - 6
Product = - 16
Factors = (-8) ; (2 {-8 + 2 = -6 ; (-8) * 2 = -16}
y = x² - 6x - 16
= x² + 2x - 8x - 16
= x(x + 2) - 8(x + 2)
= (x +2)(x -8)
b) y = 0
(x +2 )(x -8) = 0
x + 2 = 0 ; x - 8 = 0
x = -2 ; x = 8
(-2) ; 8 are the zeros.

write the equation of a line that is perpendicular to the line y=-6 and passes through the point (3,7)
Step-by-step explanation:
when two lines are perpendicular to each other( the product of their slope; m1m2 = -1)
m1 = -1/m2
m1 = -1/-6= 1/6
using the formula m= y-y1 / x - x1
1/6 = y -7 /x - 3
6(y -7) = x -3
6y -42 = x - 3
6y - x -39 =0
Divide both sides by 6
y - 1/6 x - 13/2= 0
y = 1/6 x + 13/2

Answer:
2Step-by-step explanation:
Look at the picture.
y = f(x) has the derivative f'(x) = (x + 1)²(x + 3)(x² + 2mx + 5) with ∀x∈i.
find m so that g(x) = f(|x|) has exactly 1 extreme point
9514 1404 393
Answer:
m ≥ -√5
Step-by-step explanation:
If g(x) = f(|x|) for x∈i, then g(x) = f(x) for x∈ℝ: x ≥ 0.
f'(x) is 5th-degree, so f(x) is 6th-degree, meaning it is generally U-shaped. Since we're only concerned with x ≥ 0, we want to make sure f'(x) has no real zeros of odd multiplicity such that x > 0. The given factors of f'(x) make it have real zeros at x = -3 and x = -1.
For the last factor, (x² +2mx +5) to have no positive real zeros of odd multiplicity, we must have m ≥ 0 or the discriminant ≤ 0. The discriminant is ...
d = b² -4ac = (2m)² -4(1)(5) = 4m² -20 . . . . . discriminant of the last factor
d ≤ 0 . . . . . . . . . . the condition for no real zeros
4m² -20 ≤ 0
m² -5 ≤ 0 . . . . . . divide by 4
m² ≤ 5 . . . . . . . . .add 5
|m| ≤ √5 . . . . . . . take the square root
This tells us there will be a positive real zero of multiplicity 2 in f'(x) when m = -√5, and there will be no positive real zeros for -√5 < m < 0
There will be no odd-multiplicity positive real zeros in the derivative function f'(x) as long as m ≥ -√5. This means the slope of f(x) is non-negative for x ≥ 0, hence f(|x|) has its only minimum at x=0.
_____
Additional comment
The multiplicity of the zeros of f'(x) is important because the derivative will only change sign where the multiplicity is odd. When the discriminant of (x²+2mx+5) is zero, the associated positive real zero will have multiplicity 2, hence f'(x) will not change sign there.

Write the equation of the line in fully simplified slope intercept form
Answer:
y = -x + 8
Step-by-step explanation:
In writing an equation of a line, keep in mind that you ALWAYS need the following information in order to establish a linear equation:
1. 2 ordered pairs (x,y) on the line
2. Slope
We'll use points (1, 7) and (0, 8).
Let (x1, y1) = (1, 7)
(x2, y2) = (0, 8)
Now that we have the two ordered pairs, substitute their values into the following slope formula:
m = (y2 - y1)/(x2 - x1)
m = (8 - 7) / (0 - 1)
m = 1 / -1 = -1
Therefore, the slope of the line, m = -1.
Next, we need to determine the y-intercept, (b). The y-intercept is the y-coordinate of the point (0, b ) where the graph crosses the y-axis. The y-intercept is also the value of y when x = 0. Looking at the graph, we can see that it crosses the y-axis at point (0, 8). We used this point earlier to solve for the slope. The y-intercept, b = 8.
Therefore, the linear equation in slope-intercept form is: y = -x + 8.
Please mark my answers as the Brainliest if you find this helpful :)
Answer:
y = –x + 8
Step-by-step explanation:
the line is negative and decreasing by –1/1 (rise over run is the slope). a slope of 1 can be represented by writing "x". in this case the slope is –x. the b in mx+b represents the y-value that the graph starts at. in this it starts at 8.
