Answer:
The value of the expression is 21
Step-by-step explanation:
You need to plug 5 into z
Expression:
5z-4
5(5) - 4
Notice that 5 shall be multiplied meaning 5 x 5
25-4
= 21
It's 21 since 5 times 5 is 25 subtracted 4 is 21
thought it was something else

What is the slope-intercept equation for this line?
Answer:
the slope intersection is xy
y=-3x+4
Solution:We are given 2 points: (1,1) and (0,4)We can use these points to find the slope of the line:[tex]m=\displaystyle\frac{y2-y1}{x2-x1}[/tex][tex]\displaystyle\frac{4-1}{0-1}[/tex][tex]\displaystyle\frac{3}{-1}[/tex][tex]-3[/tex]Now, let's identify the y-intercept.The y-intercept is the point where the graph touches the y-axis.Since the graph touches the y-axis at (0,4) the y-intercept is equivalent to (0, 4) or 4.Hope it helps.

The following statement is a Contingency: (P and (P => Q)) => Q T True F False
The statement (p and (p => q)) => q) is not a contingency because of it evaluating to only true while a contingency statement includes both true values and some false values.
What is a contingency statement?Contingency is a statement in which there are some true and some false values for every value of its propositional variables.
The statement given is (p and (p => q)) => q), or in more symbolic way, it is: ((p ∧ (p → q)) → q)
Now, let we evaluate it for p = False, and q = False.
Then we get:
(p → q) = T (as False implied False)
Now, (p ∧ (p → q)) is F and T which is F
Then, ((p ∧ (p → q)) → q) is F → F which is True, or T.
Thus, p = F,and q = F makes ((p ∧ (p → q)) → q) = T
Similarly, the truth table for the statement (p and (p => q)) => q) or simply ((p ∧ (p → q)) → q) is:
p q ((p ∧ (p → q)) → q)
F F T
F T T
T F T
T T T
Since all the values are true, thus, this isn't a contingency.
Thus, the statement (p and (p => q)) => q) is not a contingency because of it evaluating to only true while a contingency statement includes both true values and some false values.

Answer:
—7/3
Step-by-step explanation:
1) Choose two points on it.
like (1,3) and (4,—4)
2) slope is
[tex]slope = \frac{y2 - y1}{x2 - x1} = \frac{3 + 4}{1 - 4} = \frac{7}{ - 3} = - \frac{7}{3} [/tex]

[tex]\rightarrow[/tex]Let the women's height be AE and distance between the women and tower be AC.
Also let the height of tower be BC.

Answer:
61.24 m to the nearest hundredth.
Step-by-step explanation:
tan 50 = H / 50
H = 50 tan 50
Height of the tower = H + height of the woman
= 50 tan 50 + 1.65
= 61.2377 m
Find all relative maximum and minimums of f(x) =2x^3-3x^2-12x+5 Explain your steps in detail.
Answer:
The relative minimum is (3,-4) and the relative maximum is (-2,1)
Step-by-step explanation:
The first step is to take the derivative of f(x)
By using the power rule which is d/dx x^n=nx^n-1 you will find that the derivative is 6x^2-6x-12
The next step is to set the derivative = to 0 and by doing that you will obtain x being equaled to -2 and 3
Put -2 and 3 on a sign chart and determine the behavior for both of those functions
The outcome of your sign chart should be + - + because of the odd multimplicity of (x-3) and (x+2).

By plugging in 3 into f(x), you get -4 and by plugging in -2 into f(x) you get 1

I WILL GIVE YOU 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS AND EXPLAIN WHY THAT IS THE ANSWER. A ramp formed the angles shown to the right. What are the values of A and B?
Answer:
A=167⁰, B=13⁰
Step-by-step explanation:
A=167⁰
B=13⁰
I HOPE IT HELPED YOU
Answer:
a° = 167°, b° = 13°
Step-by-step explanation:
since the angles in a triangle add to 180°, we can work out b°
90° (right angle) - 77° = 167°
180° - 167° = 13°
since the angle of a straight line is also 180°, a° would be 180° - 13° which is 167°.

The change that will occur to the mean, median, mode of the data matched as follows:
1. e
2. b
3. d
4. a
5. c
What is the Mean fo a Data Set?To find the mean, the sum of all the values is divided by the number of values.
Given the data, 90, 85, 35, 70, 67, 76, 90, 79, 94, 100, 87, 61, 56, 80, 67, 65, therefore:
1. 35 is an extreme value, so it is an outlier. If we remove 35, the greatest change will be on the mean. (e)
2. If we remove 90, 67 will have the highest frequency. This means the mode of the data will change to 67. (b)
3. If 76 is removed from the data, the median of the data would be 79. (d)
4. If we remove 100, the range of the data would be, 94 - 35 = 59. (a)
5. If we remove 94, the mean of the data = 1108/15 = 73.87
This means the mean of the data will change to 73.87 if we remove 94. (c)

system: (-1,0)
Step-by-step explanation:
One way to solve a system of equations is to graph them. The solution is the point of intersection (where the lines cross). If you need to give the x-value and y-values separately, the first number in the pair is the x and the second number is the y.
Here’s a graph of a linear function. Write the equation that describes that function. Express it in slope-intercept form.
