Answer:
2 cars
Step-by-step explanation:
105 + 895 + 1120 = 2120
He has to pay 2120 of downpayment
2120 - 1919 = 201
Subtract what he already has
He needs 201 more dollars to rent his first apartment
He needs to do 1.21818182 cars...
You cant do 1/5 of a car so he has to do 2 cars
Multiply (−7)(2)(−2).
−28
−14
28
14
Answer:
28
Step-by-step explanation:
Answer:
Positive 28
Step-by-step explanation:
When We Multiply (-7) With (2) We get -14. That 14 Is negative An Negative number multiplied by a positive number Equals an negative number.
Rule
Pairs of numbers that are the same sign combine to make a positive product.
(Positive) ⋅ (Positive) = Positive
(Negative) ⋅ (Negative) = Positive
Rule
Pairs of numbers that are opposite signs combine to make a negative product.
(Positive) ⋅ (Negative) = Negative
(Negative) ⋅ (Positive) = Negative
After we have (-14) we still need to multiply it by (-2) Which gives us -28 But WAIT. 2 Negative numbers in a problem will result in a positive number being your answer if its the last part of the problem!
Hope this helps!

The image of point F after a rotation of 180° counterclockwise around the origin is located at (8,-10)
What is rotation?Rotation means the circular movement over the object around the center.
Rotation can be done in both directions like clockwise as well as counter clockwise
It requires rotation implies negative magnitude
A counter clockwise turns has a positive magnitude.
here, we have,
to determine the image of F:
The coordinate of point F is given as:
F = (-8,10)
The rule of rotation by 180° counterclockwise around the origin is:
(x,y) -> (-x,-y)
So, we have:
F' = (8,-10)
Hence, the image of point F is located at (8,-10)

Each morning librarians place 560 books on a book shelf in the school library. Each student that visits library that day takes exactly 3 books from this shelf. Let s be the number of students which visit library on a particular day. Let b be the number of books left on the shelf at the end of that day.

There are 150 students studying in this school. Use this information to find the domain of the function b(s).
Answer:
The domain of the function b(s) is
[tex]s\in[0,150][/tex]
Step-by-step explanation:
Given that, a total of 560 books is added to the book shelf each morning.
[tex]s[/tex] be the number of the students who visit the library on a particular day and takes exactly 3 books from this shelf.
So, the number of books they take from the shelf is 3s.
The number of remaining books the shelf [tex]=560-3s[/tex].
As , given that [tex]b[/tex] be the number of books left on the shelf at the end of that day, so the required function, [tex]b(s)[/tex], is
[tex]b=560-3s\;\cdots(i)[/tex]
As there are 150 students in the school. So, if no one will go to the library, than [tex]s=0[/tex] which is the minimum value, and if all goes to the library , than [tex]s=150[/tex] which is the maximum value of [tex]s[/tex].
So, the possible value of s is:
[tex]0\leq s\leq150\;\cdots(ii)[/tex]
Now, as there is no book left or there are some books left the negative value of [tex]b[/tex] is not possible. So,
[tex]b\geq0[/tex]
[tex]\Rightarrow 560-3s\geq0[/tex] [fron equation (i)]
[tex]\Rightarrow s\leq 560/3[/tex]
[tex]\Rightarrow s\leq 186\frac{2}{3}[/tex]
as s id the number of students which cant be a fractional value, so the possible nearest value is,
[tex]s\leq 186\;\cdots(iii)[/tex]
From the equations (ii) and (iii), the domain of the function [tex]b(s)[/tex] is
[tex]s\in[0,150][/tex]

3. A car and a truck were travelling in the same direction along the same road. The
car was travelling at a constant speed of 70 km/h and the truck was travelling at
a constant speed of 58 km/h. At 08:00, the truck was 20 km ahead of the car. Half
hour later, the truck broke down.
a) How far was the truck from the car when it broke down?
b) What time did the car pass the truck?
Take 8:00 to be the starting time, t = 0, and the car's starting position 20 km behind the truck to be the origin. Then the car's position at time t is
x = (70 km/h) t
and the truck's position is
x = 20 km + (58 km/h) t
(a) Right before the truck breaks down 0.5 h later, it will cover an additional distance of
(58 km/h) * (0.5 h) = 29 km
from its starting point, while the car will have covered a distance of
(70 km/h) * (0.5 h) = 35 km
from its starting point. So at 8:30, the truck is (20 km + 29 km) - 35 km = 14 km away from the car when it broke down.
(b) If neither vehicles stops, then the car passes the truck when their positions are equal, which would happen after
(70 km/h) t = 20 km + (58 km/h) t
(12 km/h) t = 20 km
t = (20 km) / (12 km/h)
t ≈ 1.7 h
But with the truck breaking down a 8:30, it is stuck 49 km away from the origin, so we need to find when the car travels this distance:
(70 km/h) t = 49 km
t = (49 km) / (70 km/h)
t = 0.7 h = 42 min
or at 8:42.
It is known that 10% of the items produced by a certain machine end up having a flaw. If we select 7 items from the production line, a) What is the probability that at least one of them has a flaw? Part b) What is the probability that exactly three of them has a flaw?
Step-by-step explanation:
p = 0.1, q = 0.9, n = 7
a) Use complementary probability.
P(at least 1) = 1 − P(0)
P(at least 1) = 1 − (0.9)⁷
P(at least 1) = 0.522
b) Use binomial probability.
P = nCr pʳ qⁿ⁻ʳ
P(3) = ₇C₃ (0.1)³ (0.9)⁴
P(3) = 0.023

Diego wrote f(x)=(x+2)(x−4) as an example of a function whose graph has x-intercepts at x=−4, 2. What was his mistake?
Taking into account the factored form, Diego's mistake was to express the opposite signs to those he should have.
The function f(x) = ax² + bx + c
with a, b, c real numbers and a ≠ 0, is a function quadratic expressed in its polynomial form (It is so called because the function is expressed by a polynomial).
The following expression is called discriminant:
Δ= b²- 4*a*c
The discriminant determines the amount of roots of the function. The roots are those values of x for which the expression is 0, so it graphically cuts the x-axis.
Then:
If Δ <0 the function has no real roots and its graph does not intersect the x-axis. If Δ> 0 the function has two real roots and its graph intersects the x-axis at two points .If Δ = 0 the function has a real root and its graph intersects the x-axis at a single point that coincides with its vertex. In this case the function is said to have a double root.Every quadratic function can be factored based on its roots as:
f(x)= a(x-x1)(x-x2)
where x1 and x2 are the roots of the function. This way of expressing the quadratic function is called the factored form.
If the function does not have real roots (Δ <0) it cannot be factored, that is, it does not have a factored form.
If the function has a double real root (Δ = 0) the factored function takes the form:
f(x)= a(x-x1)²
In this case, the function has x-intercepts at x=−4, 2. So, an example of the factored form is:
f(x)=[x-(+2)][x-(-4)]
f(x)=(x-2)(x+4)
Finally, Diego's mistake was to express the opposite signs to those he should have.
