x = 18.4
Step-by-step explanation:
For this problem, we are going to use the cosine function to find x:
[tex]\cos{45°} = \dfrac{adj}{hyp} = \dfrac{13}{x}[/tex]
[tex]\Rightarrow x = \dfrac{13}{\cos45°} = 18.4[/tex]

Answer:
The function is negative for all real values of x where
-6 < x < -2.
Step-by-step explanation:
f(x) = (x +2)(x + 6)
x + 2 = 0 or x + 6 = 0
x = -2 or x = -6
After graphing the function is negative between -6 < x < -2
The true statement about the graph is (a) The function is negative for all real values of x where -6 < x < -2.
The equation of the function is given as:
[tex]f(x) = (x + 6)(x + 2)[/tex]
From the graph, we have the following highlights
The values of the function decreases from negative infinity till x = -4The values of the function increases from x = -4The values of the function is negative for x = -6 to x = -2The above means that:
The function is negative for all real values of x where -6 < x < -2.
Hence, the true statement about the graph is (a)

Which of the following does not describe slope?
Answers
Answer:B is correct.
Step-by-step explanation:
Slope is a rate of change, so A is correct. Slope can be found on a graph by counting the vertical change (rise) over the horizontal change (run);
The rest of the answers say that slope is a constant rate of change, a proportional relationship, and a measure of change. Which are all true. The only one that doesn’t quite line up to what slope means is the first answer choice (a line joining points)

A grocery store sells bananas for $0.59 per pound. On Wednesdays, the store offers a 10% discount to senior citizens. Create a function f(x) which models the amount, in dollars, a senior citizen would pay for x pounds of bananas on a Wednesday.
Answers
Answer:
f(x)= 0.90(0.59x)
Step-by-step explanation:
The 10% discount will make it so the senior citizens will pay 90% of the price. 90%=0.90
Also we need to know that 0.59x means how much money per pound the bananas cost.
So when you put it together, you should get f(x)=0.90(0.59x)
Consider two congruent square prisms each rectangular face of prism A has a width of 2x+3 and each rectangular face of prism B had a length of 4x+6 if each rectangular face of prism A has and area of 25x+25 what is the volume of prism B (round to the nearest whole number)
Answers
Answer:
Step-by-step explanation:
prism A side area is square of side length
(2x + 3)² = 25x + 25
4x² + 12x + 9 = 25x + 25
4x² - 13x - 16 = 0
x = (13 ±√(13² - 4(4)(-16))) / (2(4))
positive answer is
x = (13 +√425)/8 which is approximately 4.20194...
so side length of B is
4((13 +√425)/8) + 6 which is approximately 22.80776...
Volume is side length cubed
V = (4((13 +√425)/8) + 6)³ which is approximately 11,864.4643...
V = 11,864 units³

How many numbers less or equal to 300 are divisible by 3, 4, or both, but not by 9?
Answers
The numbers less or equal to 300 that are divisible by 3, 4, or both, but not by 9 are 142.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have a 3 - digit number as 300.
Assume that the numbers less or equal to 300 that are divisible by 3, 4, or both, but not by 9 are [x].
Sequence of numbers divisible by 3 -
3, 6, 9, 12, ...., 300
300 = 3 + (n - 1)3
297 = 3n - 3
n(3) = 100
Sequence of numbers divisible by 4 -
4, 8, 12, ..., 300
300 = 4 + (n - 1)4
296 = 4n - 4
n(4) = 75
Sequence representing numbers less than 300, divisible by 9 -
9, 18, 27, ..., 297
297 = 9 + (n - 1)9
n(9) = 33
So, the numbers less or equal to 300 that are divisible by 3, 4, or both, but not by 9 are -
[x] = n(4) + n(3) - n(9)
100 + 75 - 33
175 - 33
142
Therefore, the numbers less or equal to 300 that are divisible by 3, 4, or both, but not by 9 are 142.

7) (Extra Credit) A chemist needs to mix a 12 % solution with a 20% solution to obtain 180 ounces of a 15% solution. How many ounces of each of the solutions must be used? 12%________ 20%__________
Answers
Answer:
Step-by-step explanation:
Let x be the amount of 12%
Let y be the amount of 20%
x + y = 180
x = 180 - y
x(0.12) + y(0.20) = 180(0.15)
(180 - y)(0.12) + y(0.20) = 27
(180)(0.12) - 0.12y + 0.20y = 27
21.6 + 0.08y = 27
0.08y = 5.4
y = 67.5 oz of 20% solution
x = 180 - 67.5 = 112.5 oz of 12% solution

Without graphing, describe the transformation from the parent function
f(x) = | x |.
1. y = 5| x |
2. y = 1/3 I x I
3. y = 3| x |
Answers
Answer:
1. y = 5|x| ⇒vertical stretch
2. y = ⅓|x| ⇒vertical compression
3. y = 3|x| ⇒vertical stretch
Step-by-step explanation:
Given the parent absolute value function, f(x) = |x|:
1) y = 5|x|The transformed function, y = a|x|, where |a| > 1, represents the vertical stretch of the parent graph by a factor of a.
A vertical stretch is a transformation to the parent function where there is an increase in distance between corresponding points of a graph.Therefore, the absolute value equation, y = 5|x|, represents a vertical stretch of the parent function by a factor of 5. The graph of y = 5|x| is narrower than the parent function, f(x) = |x|.
2) y = ⅓|x|The transformed function, y = a|x|, where 0< |a| < 1, represents the vertical compression of the parent graph by a factor of a.
A vertical compression is a transformation to the parent function where there is a decrease in distance between corresponding points of a graph.Therefore, the absolute value equation, y = ⅓|x|, represents a vertical stretch of the parent function by a factor of ⅓. The graph of y = ⅓|x| is wider than the parent function, f(x) = |x|.
3) y = 3|x|
Similar to question 1, the absolute value equation, y = 3|x|, represents a vertical stretch of the parent function by a factor of 3. The graph of y = 3|x| is narrower than the parent function, f(x) = |x|.
Attached are the graphs of the given absolute value functions, where it shows the transformations to the parent function, f(x) = |x|.
