Answer:
a) cannot be determined
b) a triangle can be drawn, but its dimensions cannot be determined
Step-by-step explanation:
a)The vertical axis is labeled in units of kilometers. The horizontal axis is labeled as distance, with no units given. The line shown appears to descend from 12 units above ground level over a distance of 34 units along ground level. One could argue the slope is 12/34 = 6/17, but there is no indication the horizontal units are the same as the vertical units.
The slope of the graph cannot be determined, because we don't know the horizontal units.
__
b)You can draw the triangle, but you cannot determine its dimensions.

Step-by-step explanation: Since the y value is 2 when the x value is zero, the initial value is 2.
How do I solve this?
Answer:
x° = 54.5°
Step-by-step explanation:
The measure of angle x is half the difference of the intercepted arcs. The larger arc is shown as 141°. The smaller one must be computed from the arcs shown:
360° -187° -141° = 32°
So, the measure of x° is ...
x° = (141° -32°)/2
x° = 54.5°

standard deviation is a measure of how many data points different from the mean each individual data point is.
if the standard deviation is 7, the range is +7 and -7 68% of the time
the data will be within 2 standard deviations +14 -14 95% of the time
the data will be within 3 standard deviations +21 -21 99.7% of the time
Question 6
Express this decimal as a fraction.
?
1.21 =
^ it has a line over the 21
Answer:
120/99 is the answer.
Step-by-step explanation:
It has a line over it means that after the point there are infinite numbers of 21.
•Multiply 1.212121... with 100
we get 121.212121...
•Subtract it with the original one
121.212121.. - 1.212121... = 120.000.. = 120
Write it as an equation :-
Let the fraction be x.
(100×x) - x = 120
100x-x = 120
or, 99x = 120
so, x = 120/99
Jonah found that the equation -2|8-6|-6=-12
Answer:
False equation: -2|8 - 6| - 6 = -10
Step-by-step explanation:
-2|8 - 6| - 6 = -12 True or false?
-2 | 2| - 6 = -12 Substract 8 - 6 = 2
-2 × 2 - 6 = -12 |2| = 2 absolute value of 2 is 2
- 4 - 6 = -12 -2 × 2 = -4 ( negative times positive = negative)
-10 = -12 False

What is the product of -3 and (4x-9)
Answer:
-12x+27
Step-by-step explanation:
blah blah blah blah blah
Answer:
The answer is -12x+27
Step-by-step explanation:
You would just multiply the equation
-3(4x-9)
-3*4x =-12x
-3(-9)=27
it's a positive because a negative plus a negative equal a positive.
-12x+27

Which of the following rational functions is graphed below?
Answer:
A
Step-by-step explanation:
An asymptote is a line that a curve approaches, as it heads towards infinity.
It is easy to spot the asymptotes for any given rational function - simply work out which value of x would make the denominator zero.
Function A has asymptotes at x = -3 and x = 7. This is consistent with the graph, where the asymptotes are marked as red dash lines at x = -3 and x = 7
For info, function D has asymptotes at x = -7 and x = 3. So the shape of the curve would be the same as the given diagram, but it would be 4 units to the left.

a. x about 31/8
b. x about 29/8
c. x about 57/16
d. x about 61/16
Answer:
c. x about 57/16
Step-by-step explanation:
You have not specified the algorithm you use for one iteration. We will define it as follows:
The starting point is a pair of numbers that are upper and lower bounds on the solution. The iteration ends when a new value replaces one of these bounds. The final estimate of the root will be the average of the latest upper and lower bounds.
__
The given graph shows suitable initial bounds are 3 and 4. The sign of h(x) = f(x)-g(x) matches the sign of h(3) when x=7/2, so the value 7/2 will replace the lower bound at the end of iteration 1.
The new average of upper and lower bounds is (7/2 +4)/2 = 15/4. The sign of h(15/4) matches the sign of h(4), so 15/4 becomes the new upper bound at the end of iteration 2.
The new average of the bounds is (7/2 +15/4)/2 = 29/8. The sign of h(29/8) matches the sign of h(15/4), so 29/8 becomes the new upper bound at the end of iteration 3.
After 3 iterations, the bounds are 7/2 and 29/8. The average of these values is the approximate solution to the equation:
x = (7/2 +29/8)/2 = 57/16
_____
Additional comment
We have tried to be clear about what we consider to be one iteration, and how a root approximation is arrived at. The definition of these things provided by your curriculum materials may be different.
Two less than the product of 9 and a number
Answer:
9 x n - 2
to do this, think in this way:
two less than (the product of 9 and a number) is the same thing as saying
(the product of nine and a number n ) subtracted by two
you could also represent this as:
(-2) + (9 x n)

Jimmy bought a pair of jeans on sale for 30% off the regular price of $38.00. What was the discount he received at the cash register and what was the sale price (not including tax)?
Answer: He received a discount of $11.40.
Step-by-step explanation:
To answer this problem we can look at the discount he was given, in this case, it would be 30%.
We can then turn that 30% into a decimal by dividing it by 100.
30/100
This gives us 0.3
After knowing this, we simply multiply 0.3 by the original price of $38.00 and it gives us a discount of $11.40.

Answer:
40.56 ft
Step-by-step explanation:
The perimeter of a circle is equivalent to [tex]2\pi r[/tex], where r = radius. Therefore, the perimeter of a semicircle should be [tex]\frac{2\pi r}{2}[/tex]
In this case, we're given the diameter of the semicircle as 8, so we divide the diameter by 2 and get the radius as 4. Now, let's solve the circumference of the semicircle.
[tex]\frac{2*3.14*4}{2}[/tex] [tex]\frac{6.28*4}{2}[/tex] [tex]\frac{25.12}{2}[/tex] [tex]12.56[/tex]Now, we're given the lengths of the rectangle as 8, 10, and 10. The perimeter of the rectangle (excluding the inner side) is 28.
28 + 12.56 = 40.56
Therefore, the perimeter is 40.56 ft.

find the selling price
original price: $16.95
discount: 54%
tax: 4%
Answer:
$8.11
Step-by-step explanation:
Original Price: $16.95
Discount: 54% Decimal Form: .54
Tax: 4% Decimal Form: .04
Let's start with the discount...
16.95 x .54 =9.153 Round = 9.15
16.95 - 9.15=7.80
Now, for the tax..
7.80 x .04=0.312 Round = 0.31
7.80 + 0.31=8.11
Hence. the Selling price is $8.11

SP=6(4)-7=24-7=17Answer:
17 units.Step-by-step explanation:
We know that:
MS = SPGiven:
MS = 3x + 5SP = 6x - 7Solution:
3x + 5 = 6x - 7Taking the "-7" on the LHS and the "3x" on the RHS:
=> 7 + 5 = 6x - 3xAdding/Subtracting:
=> 12 = 3xDividing:
=> 3x/3 = 12/3=> x = 4Now, let's substitute the value of x into the expression of SP.
6x - 7=> 6(4) - 7=> 24 - 7=> 17 units.Hence, the measure of SP is 17 units.
