At which root does the graph of f(x) = (x + 4)(x + 735 cross the x-axis?
9514 1404 393
Answer:
both of them: x = -4, x = -735
Step-by-step explanation:
The meaning of "real root" is that the graph intersects the x-axis at that value of x. If the degree of the root is odd, the graph crosses there. (If the degree of the root is even, the graph only touches the x-axis.)
f(x) = (x +4)(x +735)
has real roots at x = -4 and x = -735, so crosses the x-axis in those places.

7. A box contains 10 black, 12 white, and 18 red balls. One ball is drawn at
random and replaced. (a) Find the theoretical probability that the ball
drawn is black. (b) Balls are chosen and replaced 40 times. Look at the
table below, find the experimental probability that the ball drawn is black.
(c) Compare the experimental probability of the black ball drawn to its
theoretical probability.
Table:
Color. Times picked
black. 15
white. 12
red. 13
Answer:
1. 10/40 = 1/4
1b. 15/40 = 3/8
1c. 10/40 = 1/4 and 15/40 = 3/8
Step-by-step explanation:
1. So since there are 40 balls (18 + 12 + 10) and 10 of those balls are black the theoretical probability would just be 10 over 40, ([tex]\frac{10}{40}[/tex]).
1b. On the table there are 15 black balls so that would be, [tex]\frac{15}{40}[/tex].
1c. The theoretical probability is 1/4 and the experimental probability is 3/8.

In a store 8/300 of the shirts are yellow and 86/600 Are orange what percent of the shirts are not yellow or orange
Answer:
83%
Step-by-step explanation:
8/300 = 16/600
86 + 16 = 102
that leaves 498 that are not yellow or orange
so, 498/600 = 0.83 or 83%
find f(3) for the polynomial function F(x)=x^3-9x^2+5x-2
Answer:
f(3) = -41
Step-by-step explanation:
f(x) = x³-9x²+5x-2
now,
f(3) = 3³-9×(3)²+5×3-2
= 27-9×9+5×3-2
= 27-81+15-2
= -41

Answer: f(3)=g(3)
Step-by-step explanation:
The graphs intersect at x = 3.
The statement "f(6) = g(3)" is true.The correct option is A.
What is a graph?A graph is a structure that amounts to a set of items where some pairs of objects are in some manner "related" in discrete mathematics, more specifically in graph theory.
From the graph, we can see that the value of f(6) is 2, and the value of g(3) is also 2.
The statement "f(3) = g(3)" may or may not be true, as we do not know the values of f(3) and g(3) from the graph.
The statement "f(3) = g(6)" is not true, as the value of f(3) on the graph is -2, and the value of g(6) is 4.
The statement "f(6) = g(6)" is also not true, as the value of f(6) on the graph is 2, and the value of g(6) is 4.

Demetri wakes up at 9:15. It takes him
35 minutes to fold 4 loads of laundry,
35 minutes to bathe the dog, 45 minutes
to bake brownies, and 1 hour to mow the
lawn. After he finishes all of his chores,
he sits down to rest. What time does
Demetri rest?
Answer:
12:10Step-by-step explanation:
We need to add up the times:
35 mins+ 35 mins + 45 mins+ 60 mins= 35+35+45+60= 175 mins
In hours, that would be 2 hrs, and 55 mins
So; 9:15 + 2 hrs and 55 mins= 12:10
Find the midpoint M of CD
C = (-2,-10) D = (-6,0)
M = ([?],[ ]
Answer:
[tex] M = (-4, -5) [/tex]
Step-by-step explanation:
Given:
C = (-2, -10) and D = (-6, 0)
Required:
Midpoint M of segment CD.
Solution:
[tex] M = (\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}) [/tex]
Where,
[tex] (-2, -10) = (x_1, y_1) [/tex]
[tex] (-6, 0) = (x_2, y_2) [/tex]
Plug in the values into the equation
[tex] M = (\frac{-2 + (-6)}{2}, \frac{-10 + 0}{2}) [/tex]
[tex] M = (\frac{-8}{2}, \frac{-10}{2}) [/tex]
[tex] M = (-4, -5) [/tex]

Answer:
330
Step-by-step explanation:
123.75 : 15= 8,25--> the money you earn in one hour.
8,25 x 10= 82,50--> the money you earn in 10 hours.

Ryan and Carl each get paid a basic pay of £60 per day.
One day, Ryan also gets a bonus of 25% of his basic pay.
Carl also gets £20 in tips from customers.
Work out the difference between the total amounts of money that Ryan and Carl each get.
Answer:
Difference between both pay = £5
Step-by-step explanation:
Given:
Basic pay of Ryan = £60 per day
Basic pay of carl = £60 per day
Ryan get bonus = 25% of basic pay
Carl get = £20 as tip
Find:
Difference between both pay
Computation:
Total of Ryan pay = 60 + 25%(60)
Total of Ryan pay = 60 + 15
Total of Ryan pay = £75
Total of Carl pay = 60 + 20
Total of Ryan pay = £80
Difference between both pay = 80 - 75
Difference between both pay = £5

A farmer would like to estimate the mean amount of
milk produced per day by his 300 cows. He selects a
random sample of 15 cows and records the amount of
milk produced in gallons) by those cows. The dotplot
shows the data. Given that all of the recorded values are integers, what is the value of the standard error of the mean?
0.765
0.792
2.267
2.346
Answer:
0.765
Step-by-step explanation:
The dot plot shows the data
x= 20,21,22,23,24,24,25,25,25,26,26,27,28,29,31
The mean x`= ∑x/n =20+21,+22,+23,+24,+24,+25,+25,+25+,26+,26+,27+,28+,29+,31/15= 376/15
=25.067
where n is the sample size= 15
The standard deviation is σ=2.96
( using calculator)
The standard error is calculated as
SE= σ/√n
SE= 2.96/√15
SE= 0.765

The table below shows the values for the function
y = f(x).
Complete the table for the
function
y = f(1/5x).
Given:
The table of values of function [tex]y=f(x)[/tex] is given.
To find:
The table of values of function [tex]y=f(\dfrac{1}{5}x)[/tex].
Solution:
The horizontal stretch is defined as:
[tex]g(x)=f(ax), 0<a<1[/tex]
Here, f(x) is horizontally stretched by factor a to get g(x).
The given function is:
[tex]y=f(\dfrac{1}{5}x)[/tex]
It means the function [tex]y=f(x)[/tex] is horizontally stretched by factor [tex]\dfrac{1}{5}[/tex] to get [tex]y=f(\dfrac{1}{5}x)[/tex].
So, we need to multiply the given x-values by 5 to get the required table of values.
Therefore, the required table of values is:
x y
