Answer:
AROC =6
Step-by-step explanation:
Let f(x)=6x-9
When x=2
f(2) =6(2)-9 = 3
When x=0
f(0)=6(0)-9 =-9
So, average rate of change AROC=[tex]\frac{3-(-9)}{2-0} =\frac{12}{2}[/tex] =6
So, AROC=6
0.4x - 1.2 = 0.15x + 0.8 ?????????
Answer:
x = 8
Step-by-step explanation:
0.4x - 1.2 = 0.15x + 0.8
0.4x - 1.2 + 1.2 = 0.4x
0.15x + 0.8 + 1.2 = 0.15x + 2
0.4x = 0.15x + 2
0.4x - 0.15x = 0.25x
0.15x + 2 - 0.15x = 2
0.25x = 2
0.25x / 0.25 = x
2 / 0.25 = 8
x = 8
Henry's dinner bill is $132 the sales tax of 10% he lives at it of 15% how much will I pay in tax how much does it pay in tip what is his total bill
Answer:
$165
Step-by-step explanation:
Dinner bill = $132
Sales tax = 10% of dinner bill
Tip left = 15% of dinner bill
Amount of sales tax :
10% of $132
0.1 * $132 = $13.2
Amount of tip left :
15% * $132
0.15 * $132 = $19.8
Total bill :
Dinner cost + sales tax + tip
$132 + $13.2 + $19.8
= $165

Neptune's average distance from the Sun is 4.503 × 109 km. Mercury's average distance from the Sun is 5.791 × 107 km. About how many times farther from the Sun is Neptune than Mercury
9514 1404 393
Answer:
Step-by-step explanation:
The ratio of distances is ...
Neptune distance / Mercury distance = (4.503×10^9)/(5.791×10^7)
= 450.3/5.791 = 77.76 . . . . cancelling factors of 10^7
Neptune is about 77.76 times as far from the Sun as Mercury is.
Duncan is running to raise awareness and money for cancer. He finds 2 people who have pledged to
donate money based on the distance he runs. His neighbor says he will donate $0.25 for every 40 feet
Duncan runs. His aunt also says that she will donate $12 for every mile he runs. If Duncan runs a total of
7 miles during the cancer awareness run, how much money will he have raised based on these two
donations?
Answer:
$1008
Step-by-step explanation:
12 x 7 = $84 his aunt gives him.
1 mile = 5,280 feet
5,280 x 7 = 36,960 feet he ran.
5,280 ÷ 40 = 132 for every mile he runs
132 x 7 = $924 from his neighbor.
924 + 84 = 1,008

what is the value of z?
Answer:
3 (z = 35)
Step-by-step explanation:
(22 + 19) + 104 + z = 180° => triangle sum theorem
41 + 104 + z = 180
145 + z = 180
145 + z - 145 = 180 - 145
z = 35

If the initial velocity stays the same, but the height the projectile is launched from changes , how would the amount of time change that it takes for the projectile to reach its maximum height? How would its maximum height change?
Answer:
Part A
The height to which the projectile reaches is given by the following formula;
[tex]\Delta y = y-y_0 = v_{0y} \times t-\dfrac{1}{2} \times g \times t^2[/tex]
Where;
[tex]v_{0y}[/tex] = The initial velocity of the projectile = Stays the same
y = The height the projectile reaches
y₀ = The height from which the projectile is launched
g = The acceleration due to gravity
t = The time taken
Given that the projectile has the same initial velocity, the variation of Δy with time, 't', will be the same when the project is launched from a different height, and the time change that it takes for the projectile to reach the maximum height will be the same for the previous launch height
Part B
From the change in eight of the projectile, Δy = y - y₀, the maximum height reached, 'y', is therefore given as follows;
y = Δy + y₀
The maximum height will increase by 'y₀', where 'y₀' is the difference between new height and the previous height, [tex]y_i[/tex]
That is, if y₀ > [tex]y_i[/tex], the maximum height reached increases and if y₀ < [tex]y_i[/tex], y₀ will be added as y = Δy - y₀ and the maximum height reached decreases

Round the following real number to the nearest hundredth: 67.498
Answer:
67.50
Step-by-step explanation:
Answer:
67.5The hundredth is always the second number after the decimal point (to the right).
So, when rounding to that number look at the number on the right of it, which in this case is 9.
Then, if the number is 5 to 9, round up, but if it is 0 to 4, round down.
In this case, the number above 0.49 is 0.5.

Leilani hung a triangular pennant for her favorite baseball team in her room as shown below.
If the area of Leilani’s pennant is 82.65 in.2, what is the measure of the base in inches?
Answer:
Step-by-step explanation:
recall the area of a triangle is Area = 1/2* Base* height
then we know the height, and the area solve for the base
I'll do the algebra symbolically so you can see how
A = 1/2 *B * H ( start here)
2A/H = B ( move to here )
Now plug in what you know on the left side
2*82.65/17.4 = base
9.5 = base :)

Answer:
a diagram is necessary. please provide a diagram.
The value of measure of angle R is,
⇒ m ∠R ≈ 22.62°
What is mean by Angle?An angle is a combination of two rays with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
Reference angle = R
Side opposite to R = 5 cm
Adjacent side length = 12 cm
Thus, applying TOA, we have:
Tan R = opposite/adjacent
Tan R = 5/12
R = tan⁻¹ (5/12)
R ≈ 22.62°
Thus, The value of measure of angle R is,
⇒ m ∠R ≈ 22.62°
