Answer:
83 m
Step-by-step explanation:
The computation of the length of the wire is shown below:
Let us assume the length of the wire be x
Given that
There is 35m from the base of the tower
And, the angle with the ground is 65 degree
So, the length of the wire is
cos 65 = 35 ÷ x
x = 35 ÷ cos 65
= 83 m
Tom has some toy cars. 25 of them are red. He has 35 more green cars than red cars. The remaining 15 toy cars are yellow. Tom decides to pack 5 toy cars of the same colour in a box. How many more boxes of red and green toy cars are there than boxes of yellow toy cars?
Answer:
Step-by-step explanation:
red = 25
green = 25 + 35 = 60
yellow = 15
red = 25/5 = 5
green = 60/5 = 12
yellow = 15/5 = 3
Red + green = 5 + 12 = 17 boxes
yellow = 3 boxes
17 - 3 = 14 boxes
There are 14 more boxes of red and green cars than yellow cars.

Answer:
full arrow going left from 46
Step-by-step explanation:
Inequalities are used to represent unequal expressions.
The inequality is: [tex]h \le 46[/tex]
The height (h) is said to be no greater than 46 inches.
The text "no greater than" means less than or equal to.
In inequalities, less than or equal to is represented with <=
So, the inequality is:
[tex]h \le 46[/tex]
See attachment for the graph of the inequality.

Often scientists use rate of change equations in their study of population growth for one or more species. In this problem we study systems of rate of change equations designed to inform us about the future populations for two species that are either competitive (that is both species are harmed by interaction) or cooperative (that is both species benefit from interaction. Which system of rate of change equations below describes a situation where the two species compete and which system describes cooperative species? Explain your reasoning.
a. dx/dt= -5x + 2xy
b. dx/dt= 4x-2xy
c. dy/dt= -4y + 3xy
d. dy/dt= 2y-xy
Answer:
a: cooperative.
b: competitive.
c: cooperative.
d: competitive.
Step-by-step explanation:
The rate of change:
dx/dt
gives information about how the quantity x changes as a function of time.
If dx/dt > 0, the population x increases as the time passes.
if dx/dt < 0, the population x decreases as the time passes.
Now, let's analyze the options:
a) dx/dt= -5x + 2xy
in this case, x represents one population and y represents the other population. Where x and y should only be positive numbers because we can not have a negative population.
Notice that in this case, if y increases, then dx/dt increases.
Then we have cooperative species because the population y helps the growth of population x.
b) dx/dt = 4*x - 2*x*y
Similar to the previous case, but now as the value of y increases, the value of dx/dt decreases, then we have competitive species.
c) dy/dy = -4*y + 3*x*y
Notice that now we have the rate of change of y, in the right side, we can see that as x increases, also the rate of change dy/dt.
Then the population x helps to increase the population y, which means that the species are cooperative.
d) dy/dt = 2*y - x*y
Now as x increases, the value of dy/dt decreases, then these species are competitive.

Show all steps you took to get the answer
Answer:
[tex]90y^4-120y-360y^3+30y^2 = 30y((y - 4)(3y^2+1))[/tex]
Step-by-step explanation:

Required
Simplify
[tex]90y^4-120y-360y^3+30y^2[/tex]
Factor out 30y
[tex]90y^4-120y-360y^3+30y^2 = 30y(3y^3 - 4 - 12y^2 + y)[/tex]
Reorder the expression
[tex]90y^4-120y-360y^3+30y^2 = 30y(3y^3 - 12y^2 +y - 4 )[/tex]
Factorize
[tex]90y^4-120y-360y^3+30y^2 = 30y(3y^2(y - 4) +(y - 4) )[/tex]
Combine the factors
[tex]90y^4-120y-360y^3+30y^2 = 30y((3y^2+1)(y - 4))[/tex]

Answer:
No picture so I can’t answer the question
Step-by-step explanation:
The city of Raleigh has 6000 registered voters. There are two candidates for city council in an upcoming election: Brown and Feliz. The day before the election, a telephone poll of 250 randomly selected registered voters was conducted. 100 said they'd vote for Brown, 141 said they'd vote for Feliz, and 9 were undecided. Describe the population actually represented by this survey.
Answer:
[tex]Brown = 2400[/tex]
[tex]Feliz = 3384[/tex]
[tex]Undecided = 216[/tex]
Step-by-step explanation:
Given
[tex]N = 6000[/tex] -- population
[tex]n = 250[/tex] -- sample
From the sample, the proportions are:
[tex]B = 100[/tex] -- Brown
[tex]F=141[/tex] -- Feliz
[tex]U = 9[/tex] -- undecided
Required
Describe the actual population
The actual is calculated using:
[tex]Actual = \frac{p}{n} * N[/tex]
So, for Brown
[tex]Brown = \frac{100}{250} *6000[/tex]
[tex]Brown = \frac{100*6000}{250}[/tex]
[tex]Brown = \frac{600000}{250}[/tex]
[tex]Brown = 2400[/tex]
For Feliz
[tex]Feliz = \frac{141}{250} * 6000[/tex]
[tex]Feliz = \frac{141* 6000}{250}[/tex]
[tex]Feliz = \frac{846000}{250}[/tex]
[tex]Feliz = 3384[/tex]
For undecided
[tex]Undecided = \frac{9}{250}*6000[/tex]
[tex]Undecided = \frac{9*6000}{250}[/tex]
[tex]Undecided = \frac{54000}{250}[/tex]
[tex]Undecided = 216[/tex]

What is the missing constant term in the perfect square that starts with x^2 + 10z
Answer:
25
Step-by-step explanation:
i think you mean +10x
but (x+a)^2 = x^2 + 2ax + a^2
2ax = 10x
ax = 5x
a = 5
