Answer:
A
Step-by-step explanation:
We have the graph of the function f(x).
We want to determine which of the given is true of the graph from [tex]x=g[/tex] to [tex]x=\infty[/tex].
So, essentially, we are focusing on the last curve (see image below).
First, since the curve is above the x-axis, the curve is positive.
Second, since the curve is curving upwards, this means that it must be increasing. Another way to think about this is to think about the slope of our curve. While we can't calculate the exact slope, the average slope will be positive, so our function is increasing.
So, our answer is A.
And we're done!
Evaluate the expression when x = 4
-4x + 1.5x - 2.5 - 2x -6.5
A simple algebra equation!
You have to replace each x with 4, so the equation would look like this:
-4·4+1.5·4-2.5-2·4-6.5
Evaluate the terms, you get:
-16+6-2.5-8-6.5
Then you add and subtract where needed:
-10-16 = -27
And that's the final answer!
ANSWER: 27

if 300 people come to the gym on a given day, approximately how many people would you expect to exercise for more than 136 minutes?
===========================================================
Explanation:
Add up the numbers in the second column:
4+19+25+32 = 80
There are 80 people being surveyed in the table.
Of those 80 people surveyed, 32 of them exercised for more than 136 minutes.
The probability of selecting someone who exercised for more than 136 minutes is the fraction 32/80 = (16*2)/(16*5) = 2/5
----------
Multiply this probability with the larger sample size of 300 to get
(2/5)*300 = 0.4*300 = 120
We estimate that 120 people would exercise for more than 136 minutes.
Note that 120/300 = 2/5.

what is the best reasoning for line 3
Answer:
E
Step-by-step explanation:
"S" stands for "side" and "A" stands for "angle"
SAS = side angle side
The order is important because the angles must be between the two congruent sides.
One pair of congruent sides is AC = CE as shown by the single tickmarks.
The other pair of congruent sides is BC = CD shown by the double tickmarks
The congruent angles are the vertical angles BCA and DCE. Vertical angles are always congruent. Note how these angles are sandwiched between the tickmarked sides.

Her score was in the top 85% of all test takers' scores.
Answer:
The answer is
her score was in the top 85% of all test takers' scores.
Step-by-step explanation:
Percentile is the relative standing in a set of data from the lowest values to highest values.
If your score is in the 85th percentile, it means that 85% of the scores are below your score and 15% are above your score.

what is the area , in square feet , of the shaded part of the rectangle below?
Answer:
208 square feet
Step-by-step explanation:
Area (shaded) = Area (rectangle) - Area(triangle)
= (17 x 16) - 1/2(16 x 8)
= 16 (17 - 4)
= 16 (13)
= 208 square feet
Calculate the perimeter of the semi-circle shown below. Use 3.14 to approximate n.
========================================================
Explanation:
A full circle of radius r has the circumference of
C = 2*pi*r
A semicircle will have us divide this value in half
2pi*r turns into pi*r
The curved distance along the top is roughly pi*r = pi*5 = 3.14*5 = 15.7 cm.
Add this onto the straight line distance along the bottom to arrive at 15.7+10 = 25.7 cm

Answer:
C 13
Step-by-step explanation:
2 right-angled triangles. so, Pythagoras applies for both.
c² = a² + b²
with c being the Hypotenuse (the side opposite of the 90° angle).
starting with the small triangle we have
5² = 3² + x-part²
x-part² = 5² - 3² = 25 - 9 = 16
x-part = 4 cm
the markers indicate that x-part as the third side of the small triangle is exactly as long as the other part of x.
that means
x = 2 × x-part = 2 × 4 = 8 cm
for the large triangle we then get
y² = x² + 15² = 8² + 225 = 64 + 225 = 289
y = 17 cm
and so,
y - x = 17 - 8 = 9
but that is not an answer option.
and now it dawned on me : x was not meant to be the whole third side of the large triangle. x is supposed to be only the upper part of that side, above the small triangle.
in essence, x is what I originally called "x-part".
so, the Pythagoras calculations remain basically the same, but we should name things differently like
5² = 3² + small-side²
small-side = 4 cm
x = small-side = 4 cm
long-side = 2 × small-side = 2 × 4 = 8 cm
y² = long-side² + 15² = 8² + 15² = 64 + 225 = 289
y = 17 cm
and the actual y - x = 17 - 4 = 13 cm

What is the decimal equivalent to -3 3/12
[tex]\huge\rm{ANSWER:}[/tex]
[tex]\huge \rm{ - 3.25}[/tex][tex]\huge\rm{SOLUTION:}[/tex]
To begin, keep in mind that - 3 3/12 is a mixed number, also known as a mixed fraction. It has a valid fraction as well as a complete number.
The following is a list of the numbers in a mixed fraction:
[tex]\huge \rm{ - 3}[/tex] the whole number.
[tex]\huge \rm{ 3}[/tex] the numerator
[tex]\huge \rm{ 12}[/tex] the denominator
Follow these procedures to convert -3 3/12 from a mixed number to a decimal number:
Divide the denominator by the numerator to convert the correct fraction to decimal.
3 ÷ 12 = 0.25
To get the entire number of the mixed fraction, multiply it by this decimal number.
-3 + 0.25 = - 3.25
Therefore, the decimal equivalent to -3 3/12 is -3.25

can someone pls explain how to answer this?
Answer:
HOPE THIS HELPS
Step-by-step explanation:
You need to first plot the points on the graph.
Since, it says you need to reflect across x axis, you need same number of square units.
For example, P has the coordinates( -2,3 ). -2 lies on the x axis, so the point doesn't go neither left nor right. It is 3 squares above the x axis, so the reflected point should be 3 squares below the x axis. Likewise, you can do the other points.
Hope it helps :)

You work with a carpenter who asks you to cut trim board in the following lengths: 71/2 inches,
101/2 inches, 9 inches, and 51/2 inches. To do this using only one piece of trim board, how long
must the board be?
Length of board will be 32 1/2 inch.
What is Addition?
A process of combining two or more numbers is called addition.
Given that;
Length of board after cutting are;
7 1/2 inches, 10 1/2 inches, 9 inches, and 5 1/2 inches.
Now, Total length of board is calculated as sum of all cut lengths.
So, Total length of board = 7 1/2 +10 1/2 + 9 + 5 1/2
= 15/2 + 21/2 + 9 + 11/2
= 47/2 + 9
= 65/2
= 32 1/2
Thus, Length of board will be 32 1/2 inch.

There is a bag filled with 6 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 reds?
Answer:
Step-by-step explanation:
The first probability of it being red = 5/11
The key to the question is that you replace the red marble you took out. So there are still 5 red marbles.
You still have a 5/11 chance of getting a red marble.
P(red + red) = 5/11 * 5/11
Answer
P(red + red) = 25 / 121
