+ 4z −1)+(2z^2
− 6z +2)
Combine 4z and −6z to get −2z.
7z3 − 2z −1 + 2z2 +2

How long will it take for a $2000 investment to grow to $2786 at an annual rate of 4.6% , compounded quarterly? Assume that no withdrawals are made.
Answer:
7.4
Step-by-step explanation:
use the compound interest formula
I=P(1+r/100)<n
2786=2000(1+4.6/100)^n
divide 2000 by both side
1.393=(1+4.6/100)^n
1.393=1.046^n
introduce the log
log1.393=rlog1.046
divide both with log1.046 to get the value of n
n=7.4
4/5 of the money collected from a fundraiser was divided equally among 8 grades
What fraction did each grade receive?
Answer:
1/10
Step-by-step explanation:
your equation is 4/5 divided by 8/1.
Lets solve that problem with the acronym KCF, or
Keep
Change
Flip.
K: "keep" the first fraction, or the one you are multiplying with, so 4/5 stays the same.
C: "change" the division sign to a multiplication sign, so 4/5x8/1
F: "flip" the second fraction, so 8/1 becomes 1/8.
now our equation is 4/5x1/8. If we solve that, we get 4/40, which reduced is 1/10.

Leila runs at 12 miles per hour. Find the number of miles she can travel if she runs for k less than 6 hours.
Distance is the product of speed and time. Hence, the distance covered by Leika is 12k - 72 miles.
Given that :
Speed = 12 miles per hour Run Time = k - 6Recall :
Distance traveled = Speed × timeDistance covered by Leila can be calculated thus :
Distance = 12 × (k - 6)
Distance = 12k - 72
Therefore, the distance covered by Leila is 12k - 72 miles.

For the time k less than 6 hours, the distance that Leila travel is less than 72 miles.
The given parameters;
speed of Leila, v = 12 miles per hourtime of motion of Leila = k < 6 hoursThe maximum distance that Leila can travel in a time less than 6 hours is calculated as follows;
Distance < speed x time
Distance < 12 mph x 6 hours
Distance < 72 miles

What is the solution to the equation −p − 13 = −4 /3 p + 2/3 ( 5p − 6 ) ?
((will give brainliest to best answer
Answer:
The answer is p= 2 and 1/3
Step-by-step explanation:
This answer can be found using the order of operations to solve for p.
Start by distributing 2/3 by (5p-6)
add -4/3p to 10/3p equaling 6/3p or 2p
subtract 13 from both sides
-p= 2p - 7
p=2 and 1/3
Instructions- Solve the system of equations. Type in all points of intersection for the two functions and round to the nearest tenth if necessary.
f(x) = -0.5x+2
8(x) = -5x + 3
f(×)=-0,5x+2
8(×)= -5x+3
8×= -5x+3
8-5x+3
3x+3
x6
The nearest tenth as required, the point of intersection expressed as (0.2, 2.1).
To solve the system of equations, to find the points where the two functions intersect, which means the x-values where f(x) equals g(x). Let's proceed with the solution:
f(x) = -0.5x + 2
g(x) = -5x + 3
Set f(x) equal to g(x):
-0.5x + 2 = -5x + 3
Now, let's solve for x:
Add 0.5x to both sides to eliminate the term with x on the left side:
2 = -4.5x + 3
Subtract 3 from both sides:
-1 = -4.5x
Now, divide by -4.5 to isolate x:
x = -1 / -4.5
x ≈ 0.2222
Now that we have the x-value of the point of intersection, let's find the corresponding y-value by plugging x back into either f(x) or g(x). Let's use f(x):
f(x) = -0.5x + 2
f(0.2222) = -0.5(0.2222) + 2
f(0.2222) ≈ 2.1111
So, the point of intersection is approximately (0.2222, 2.1111).

Solve for x given the point (x,9) is a point on the line y = 3x + 7.
Answer:
0.67 = x
Step-by-step explanation:
to solve the value of x we need to : (x,9)
y = 3x + 7
9 = 3x + 7
9 - 7 = 3x
2 = 3x
2/3 = x
0.67 = x
From the given point (x , 9) let's plug the value of its y - coordinate of into Equation - y = 3x + 7 and solve for x :

Answer:
2,276 ≤ 2,336.6 < 60.6
Step-by-step explanation:
I. When m is combined mass of car and person which is
2,276 + 60.6 = 2,336.6
II. Write into the interval a <= m < b
So we can write as
2,276 ≤ 2,336.6 < 60.6 will return to False.
or
60.6 ≤ 2,336.6 < 2,276 will return to False.
That makes 2,276 ≤ 2,336.6 < 60.6 is the right answer.

Austin, Kevin and Lisa have a total of $159. Austin has $11 more than Kevin. Lisa has twice as much money as
Keyin. How much money does Lisa have?
Answer:
Step-by-step explanation:
A+K+L=159
A-K=11
2K=L
Plug in 2K instead of L in the equation: A+K+L=159
A+3K=159
Plug in K+11 instead of A in the equation: A+3K=159
4K+11=159
4K=148
Kevin=$37
Pluge in 37 instead of K in the equation: A-K=11
A-37=11
Austin=$48
Plug in 48 instead of A and 37 instead of K in the equation: A+K+L=159
48+37+L=159

You are looking at the New York ball drop on New Year’s Eve at a distance of 100 m away from the base of the structure. If the ball drops at a constant rate of 2 m/s, what is the rate of change of the
angel between you and the ball when the angle is ( ?
The question is an illustration of related rates.
The rate of change between you and the ball is 0.01 rad per second
I added an attachment to illustrate the given parameters.
The representations on the attachment are:
[tex]\mathbf{x = 100\ m}[/tex]
[tex]\mathbf{\frac{dy}{dt} = 2\ ms^{-1}}[/tex] ---- the rate
[tex]\mathbf{\theta = \frac{\pi}{4}}[/tex]
First, we calculate the vertical distance (y) using tangent ratio
[tex]\mathbf{\tan(\theta) = \frac{y}{x}}[/tex]
Substitute 100 for x
[tex]\mathbf{y = 100\tan(\theta) }[/tex]
[tex]\mathbf{\tan(\theta) = \frac{y}{100}}[/tex]
Differentiate both sides with respect to time (t)
[tex]\mathbf{ \sec^2(\theta) \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot \frac{dy}{dt}}[/tex]
Substitute values for the rates and [tex]\mathbf{\theta }[/tex]
[tex]\mathbf{ \sec^2(\pi/4) \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}[/tex]
This gives
[tex]\mathbf{ (\sqrt 2)^2 \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}[/tex]
[tex]\mathbf{ 2 \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}[/tex]
Divide both sides by 2
[tex]\mathbf{ \frac{d\theta}{dt} = \frac{1}{100} }[/tex]
[tex]\mathbf{ \frac{d\theta}{dt} = 0.01 }[/tex]
Hence, the rate of change between you and the ball is 0.01 rad per second
