a group of college students eager to get to florida on a spring break drove the 750- mi trip with only minimum stops. they computed their average speed for the trip to be 55.0 mi/h. how many hours did the trip take?
The trip took 13 hrs . and 6 min .
Given : Distance of trip from starting point to end point = 750 mi
Avg . speed for trip = 55 mi / h
To find : how many hours did the trip take
Using formula for speed :
speed = distance / time
Substituting values in above formula ,
and let time = t .
55 = 750 / t
t = 750 / 55
t = 13 . 63
≈ 13 hrs . 6 min .
Hence , the trip took 13 hours approx .

Write and equation in slope-intercept form of the line with slope -1/2 that contains the point (-4,-3)
Answer:
y=-1/2x-5
Step-by-step explanation:
Well we know that the slope is -1/2 so we can write the equation like this:
y=-1/2x+b (This is because of y=mx+b) (m is slope) (b is y-intercept)
Now we can replace the y and x with -4 and -3 because of (x,y). (-4,-3) x is -4 and y is -3
-3=-1/2(-4)+b
-3=2+b
Subtract 2 on both side:
-2-3=2-2+b
-5=b
Answer:
y=-1/2x-5

an ice-cream novelty item consists of a cup in the shape of a 4-inch-tall frustum of a right circular cone, with a 2-inch-diameter base at the bottom and a 4-inch-diameter base at the top, packed solid with ice cream, together with a solid cone of ice cream of height 4 inches, whose base, at the bottom, is the top base of the frustum. what is the total volume of the ice cream, in cubic inches?
The total volume of the ice cream, in cubic inches, is [tex]\frac{44\pi }{3}[/tex].
What is Volume?
Cubic capacity is the measurement of a three-dimensional object's volume in cubic units (such as inches, quarts, or centimeters). The volume that material takes up in a given space.Volume, which is measured in cubic units, is the 3-dimensional region occupied by matter or encircled by a surface. The cubic meter (m3), a derived unit, is the SI unit of volume.With a radius of 2 and a height of 4, the top cone has a volume of
[tex]\frac{1}{3} \pi (2)^2X4[/tex].
The frustum is created by subtracting a tiny cone with a radius of 1 and a height of 4 from a large cone with a radius of 2 and a height of 8, giving it a volume of [tex]\frac{1}{3} \pi (2)^2X8-\frac{1}{3} \pi (1)^2X4[/tex]
By combining, we have,
[tex]\frac{1}{3} \pi (16+32-4)\\\\E=\frac{44\pi }{3}[/tex].

12 members are at a conference. they all shook hands with each other both before and after the meeting. how many handshake's were there?
If there are 12 members at a conference and they all shook hands with each other both before and after the meeting, then there were 132 handshakes.
The number of handshakes before and after the meeting between 12 members can be found by using the combination formula.
The combination formula can be given by :
Number of combinations = n! / r! ( n - r)!
Here, n = total number of items in the set
r = number of choosing items from the set
In this problem, n = 12 and r =2 for finding the number of handshakes before the meeting
Therefore,
number of combinations = 12! / 2! ( 12 - 2)!
number of combinations = 12! / 10! × 2!
number of combinations = 66
Hence, there were 66 handshakes before the meeting. To find the number of handshakes both before and after the meeting:
number of total handshakes = 66 × 2 = 132
Hence the number of handshakes before and after the meeting is equal to 132.

Grace measured a line to be 15.6 inches long. If the actual length of the line is 15.3
inches, then what was the percent error of the measurement, to the nearest tenth of a
percent?
The percentage error of the measurement, to the nearest tenth of a percent 2.6%.
Given, Grace measured a line to be 15.6 inches long.
The actual length of the line is 15.3 inches.
Percentage error of the measurement = ?
Error in the measurement = 15.6 - 15.3
= 0.3 inches
Percentage error = 0.4 ÷ 15.3
= 0.02614 × 100
= 2.6%
The percentage error = 2.6%
Hence the percentage error is 2.6% .

Find the equation of the line that passes through the given points. Write the equation in slope-intercept form.
(-2.7) and (-1,5)
Answer:
The equation in the slope-intercept form will be:
y = -2x + 3Step-by-step explanation:
Given the points
(-2, 7)(-1, 5)Finding the slope between the points
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-2,\:7\right),\:\left(x_2,\:y_2\right)=\left(-1,\:5\right)[/tex]
[tex]m=\frac{5-7}{-1-\left(-2\right)}[/tex]
[tex]m=-2[/tex]
We know that the slope-intercept of line equation is
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
substituting m = -2 and the point (-2, 7) to find the y-intercept 'b'
y = mx+b
7 = -2(-2) + b
7 = 4 + b
b = 7-4
b = 3
so the y-intercept = b = 3
substituting m = -2 and b = 3 in the slope-intercept form of line equation
y = mx+b
y = -2x + 3
Thus, the the equation in the slope-intercept form will be:
y = -2x + 35a.) Evaluate f(2)
5b.) Evaluate f(4)
5c.) Evaluate f(-1)
5d.) Evaluate f(-2)
