Answer:
29.17m/s²Step-by-step explanation:
Acceleration is defined as the change in velocity of a body with respect to time.
Acceleration = velocity/time
Given velocity of the space shuttle = 525m/s and time = 18.0seconds
Its average acceleration = 525/18
Its average acceleration (in m/s²) = 29.17m/s²
find the sum -1/3+(-5/9)
Answer:
-8/9
Step-by-step explanation:
First of all you have to make -1/3 into a fraction that you can add with (-5/9).
-1/3 turns into -3/9.
-3/9 + (-5/9) is -8/9
Answer:
[tex] - \frac{8}{9} [/tex]
Step-by-step explanation:
We know that,
[tex]( + ) \times ( - ) = ( - )[/tex]
lets solve
[tex] - \frac{1}{3} + ( - \frac{5}{9} ) \\ - \frac{1}{3} - \frac{5}{9} \\ = \frac{ - 1 \times 3 - 5}{9} \\ = \frac{ - 8}{9} [/tex]

Find the value of x that makes line m parallel to line
n.
(4x - 23)
n
{
(2x + 17)
Answer:
20
Step-by-step explanation:
If lines m and n are parallel, then the labelled angles would be considered alternate exterior angles. By definition, such angles are of the same value.
Thus, we set the two expressions of 4x - 23 and 2x + 17 equal:
4x - 23 = 2x + 17
Subtract 2x from both sides and add 23 to both sides:
2x = 23 + 17 = 40
Divide by 2:
x = 40/2 = 20
The answer is thus 20.

Answer:
[tex]x=20[/tex]
Step-by-step explanation:
Alternate exterior angles are a pair of equal angles on opposite sides of the transversal.

Janella has her hair styled and wants to tip her stylist 18%. Write an equation that could be used to calculate the tip, y, for a bill total of x dollars.
Answer:
10( 3/4x * 9/500y ) = 10
Step-by-step explanation:
We know 18% can also be found
when we take the x amount 75 x 0.18 = 13.50
We thereafter find 75-13.50 = 61.50 for Janella's hair cost plus $13.50 tip.
But for x = 750 x 9/500 = 10
We find 13.50 = 10
x= 1.5
18% coincidentally is 13.5 and 13.5 x 1.5 = 18
So we could redesign and use 18 in the equation
An equation that could be used to calculate the tip, y, for a bill total of x dollars is y=0.18x.
Given that, Janella has her hair styled and wants to tip her stylist 18%.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the tip be y and total bill be y.
So, tip y = 18% of total bill x
⇒ y = 18% of x
⇒ y = 18/100 × x
⇒ y = 0.18x
Therefore, an equation that could be used to calculate the tip, y, for a bill total of x dollars is y=0.18x.

The table of values represents the function g(x) and the graph shows the function f(x).
Which statement about the functions is true?
1. f(x) is greater than g(x) for all values of x.
2. f(x) and g(x) have the same y-intercept.
3. f(x) and g(x) intersect at two points.
4.f(x) and g(x) have a common x-intercept.
===========================================================
Explanation:
For me, it helps to graph everything on the same xy coordinate system. Start with the given graph and plot the points shown in the table. You'll get what you see in the diagram below.
The blue point C in that diagram is on the red parabola. This point is the x intercept as this is where both graphs cross the x axis. Therefore, they have a common x intercept.
------------
Side notes:
Choice 1 is not true due to choice 4 being true. We have f(x) = g(x) when x = 2, which is why f(x) > g(x) is not true for all x.Choice 2 is not true. Point B is not on the parabola.Choice 3 is not true. There is only one known intersection point between f(x) and g(x), and that is at the x intercept mentioned above. Of course there may be more intersections, but we don't have enough info to determine this.what is the y-intercept, maximum point and the x intercepts of f(x)= -x^2÷1 +4
Answer:
maximum point: (0, 4)
x-intercepts: (2, 0), (-2, 0)
y-intercepts: (0, 4)

H. None of the above

Answer:
A. x
C. x – 5
D. x + 2
Step-by-step explanation:
From the question above, we are asked to find the factors of an algebraic expression that is given as:
x³ - 3x² - 10x
We would use the step of factorisation
Step 1
x(x² - 3x- 10)
The first factor of the algebraic expression has been obtained = x
Step 2
We factorise x² - 3x - 10
x² +2x - 5x - 10
(x²+2x) - (5x - 10)
x(x + 2) -5(x + 2)
(x + 2)(x - 5)
Step 3
x³ - 3x² - 10x
x(x² - 3x- 10)
(x)(x + 2)(x - 5)
Therefore, the factors of the algebraic expression are:
(x), (x + 2), (x - 5)

Answer:
132 degrees is the measure of angle ABC.
Step-by-step explanation:
ABD = 180 because it is a straight line.
BCD = 48
ABD - BCD = 180 - 48
180 - 48 = 132
Answer:
ABC =132
Step-by-step explanation:
The two angles form a straight line so they add to 180
ABC + 48 = 180
Subtract 48 from each side
ABC +48-48 = 180-48
ABC =132

Solution:
20 = m
Step-by-step explanation:
What we know:
Karim drank 1 cup of milk at breakfastKarim drank a total of 21 cups of milkm = the amount of milk, in cups, Karim drank after breakfastWe know that Karim drank 21 cups of milk in a day. In an equation, that would look like this:

What does 21 equal?
The amount of milk Karim drank at breakfast plus the amount of milk Karim drank after breakfast.
21 = milk at breakfast + milk after breakfast
Let's substitute what we know into this equation:
21 = milk at breakfast + milk after breakfast
21 = 1 + m
Now that we have our equation, let's solve.
21 = 1 + m
-1 -1
20 = m
Therefore, Karim drank 20 cups of milk after breakfast.

Answer:
150°
Step-by-step explanation:
to find the individual angle of a REGULAR dodecagon (which means that all sides are equal), you'd use the equation I(individual angle)= (n-2)×180/n
N is number of sides. The number of sides on a dodecagon is 12. So, substitute N for 12
I= (12-2)×180/12 which simplifies to 10×180/12
10×180= 1800
1800/12 = 150
so, an individual interior angle of a dodecagon is 150°
