Lamonte and Fwam own competing taxicab companies. Both cab companies charge a one-time pickup fee for every ride, as well as a charge for each mile traveled. The equation y=2.2x+2.5 represents what Lamonte's company charges. Fwam charges a $4 pickup fee and $2.80 per mile. Use the dropdown menu and answer-blank below to form a true statement.
Answers
The cab rate model for Fwam will be given as y=2.8x+4.
What is an equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Here we have an equation model for Lamonte y=2.2x+2.5 here y is the total cost and x is the distance in miles.
So here Fwam charges a $4 pick up fee and $2.80 per mile. The equation model will be:-
y=2.8x+4.
Hence cab rate model for Fwam will be given as y=2.8x+4.

4About one-half of the students are more than 46 inches tall.
(there is more than one answer)
Answers
Answer:
Below in bold.
Step-by-step explanation:
The mean is 55 therefore, by definition:
On average the students are 55 inches tall.
The median is the middle ( or the average of 2 middle) value when the data is arranged in order.
So as the media is 46 inches about half are more than 46 ins tall.

What is h(-8) for h(x) = x²

-x² +7x?
Answers
Answer:
8
Step-by-step explanation:
Re-write the equation:
h(x) = x² * 2 - x² -7x
If X is equal to -8, then we can re-write the equation as:
h(-8) = (-8)² * 2 - (-8)² - 7(-8)
Following P.E.M.D.A.S. we must first solve for the exponents:
h(-8) = (64) * 2 - (64) - 7(-8)
Then we need to solve the multiplication.
h(-8) = (128) - (64) - (-56)
Now, we solve for the addition/subraction.
h(-8) = (128) - (120)
Lastly...
128 - 120 = 8
This means that if h(-8), then H = 8

Estimate the instantaneous rate of change in the percent of households that used the internet
for electronic banking in the year 2000.
Answers
The instantaneous rate of change in the percent of households that used the internet for electronic banking in the year 2000 is; 6.8%
How to find the instantaneous rate of change?Formula for instantaneous rate of change is;
f'(x) = (f(b) - f(a))/(b - a)
From the table showing the the percent of households that used the internet for electronic banking in the year 2000, we can find the instantaneous rate of change as;
f'(2000) = (f(2001) - f(1999)]/(2001 - 1999)
f'(2000) = (21.6 - 8)/(2001 - 1999)
f'(2000) = 13.6/2
f'(2000) = 6.8

P(pass | Test A)
The probability is ____%
SHOW ALL WORK
Answers
The P(pass | Test A) is 31.81%, P(pass | Test B) is 29.87%
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
Part A:
Total number of students = 154
Total number of students passed the test = 49
The probability:
P(pass | Test A) = 49/154 = 31.81%
Part B:
Total number of students = 154
Total number of students passed the test = 46
The probability:
P(pass | Test B) = 46/154 = 29.87%
Thus, the P(pass | Test A) is 31.81%, P(pass | Test B) is 29.87%.

How do I find the radius/x of a shaded region with it's area and/or angle measurement?
Answers
Answer:
[tex]x \approx 9.823\ ft[/tex]
Step-by-step explanation:
Remember that the area of a sector is defined as:
[tex]A = \frac{\theta}{360^\circ}\times \pi r^2[/tex]
In this problem, we are given the area [tex]A[/tex], and the angle [tex]\theta[/tex]. We can set up an equation to solve for the radius, which is x:
[tex]A = \frac{\theta}{360^\circ}\times \pi r^2\\128 = \frac{152}{360}\times \pi r^2\\128 \times \frac{360}{152} = \pi r^2\\\frac{5760}{19} = \pi r^2\\r = \sqrt{\frac{5760}{19 \pi}}\\r \approx 9.823[/tex]
Answer:
r ≈ 9.8 feet
Step-by-step explanation:
Formula of A Sector
Area (Sector) = πr² × θ/360°Substitute the given values in the formula to find r.
128 = 3.14 × r² × 152/36040.76 = r² × 19/45r² = 1834.2/19r² = 96.54r ≈ 9.8 feetTriangle r q s is cut by line segment t v. line segment t v goes from side q r to side r s. the length of r v is x 10, the length of v s is x, the length of r t is x 4, and the length of t q is x minus 3. which value of x would make line segment t v is parallel to line segment q s? 3 8 10 11
Answers
The value of x that would make line segment T V is parallel to line segment Q S is where x = 10. (Option C)
What is a line segment?In Mathematics, a Line Segment is a part of a line that has two endpoints.
The difference between a line segment and a line is that while the former has a starting and an endpoint, the latter does not. See the attached image.
What is the Step by Step solution to the above problem?Step 1
Note that if QS is Parallel to TV, then both sides of the triangle must be proportionally divided by TV.
That is: RV/VS = RT/TQ.
Step 2 - replace the segments by the relevant equations
(X + 4)/(X- 3) = (X+10)/(X)
Step 3 - Cross Multiply
x(x +4) = (x -3)(x +10)
Removing the parentheses, we have
X² +4X = X² +7X -30; Subtract X² from both sides and we have;
4X = 7X - 30
Step 3 - Collect like terms by cross multiplying-3X = -30 or
3X = 30
Divide both sides by three and we have:
X = 10

Using the relation between velocity, distance and time, it is found that the commute took 48 minutes.

For Lena, we have that d = 29, v = 36, hence the time in hours is given by:

Which function has the smallest x-intercept value, if it exists? f(x) = 3x – 9 f(x) = x2
Answers
The quadratic function f(x) = x² has the smallest x-intercept value in comparison with the linear function f(x) = 3 · x - 9, which is located at x = 0.
How to determine the x-intercept of a polynomic function
x-intercept is the point of a function that goes through the x-axis. Quadratic functions have at most two x-intercepts and linear functions have always one x-intercept.
In both expressions those intercepts are found by solving expression for x when y is equal to zero. In this question we must determine the smallest x-intercept value from one of the two polynomic functions:
a) f(x) = 3 · x - 9
3 · x - 9 = 0
x = 3
b) f(x) = x²
x² = 0
x = 0
The quadratic function f(x) = x² has the smallest x-intercept value in comparison with the linear function f(x) = 3 · x - 9, which is located at x = 0.

Answers
No, there is not a rigid transformation or a combination of rigid transformations that will map ABCD to WXYZ.
What is congruency?The Side-Angle-Side Congruence Theorem (SAS) defines two triangles to be congruent to each other if the included angle and two sides of one are congruent to the included angle and corresponding two sides of the other triangle.
Two figures are congruent if their vertices can be mapped into one another by appropriate rigid transformation or a combination of rigid transformations. Examples of the transformation are; reflection, dilation, rotation and translation.
Comparing the two figures, it would be observed that they are not congruent. Since there is not a rigid transformation or a combination of rigid transformations that will map ABCD to WXYZ.
