Equation/Question:

Solve for R.

10 (r - 6) = -17

Enter the answer in the box.

Answer/Steps to answer:

1. Divide both sides by 10.

r-6=-17/10.

2. Add 6 to both sides.

r=− 17/10 +6

3. Simplify -17/10 +6 to 43/10.

r=43/10

-------------------

Checking:

10(r−6)=−17

1. Let r=43/10

10(43/10-6)=-17

2. Simplify 43/10 −6 to 17/10

10× −17/10 =−17

3. Cancel 10.

-17=-17

Help with some algebra please?

kipiarov [429]

Vertex form is f(x) = a(x - b)^2 + c where the vertex is (b, c) and a is some constant.

So for the first part we have f(x) = a(x + 6)^2 - 1

for root -9:- a( -9+6)^2 - 1 = 0
9a - 1 = 0 , a = 1/9

The other 3 are derived in the same way.
so required equation is f(x) = (1/9)(x + 6)^2 - 1

In ABC, and intersect each other at point Q. According to a theorem on medians, Q divides in the ratio 2 : 1. What are the coord

Flauer [41]

How to find rapidly the coordinates of Q:
since Q is the center of gravity of the triangle ABC, so we have the following vector relationship
vecQA +vecQB +vecQC =vec0
vecQA=(x-3, y+2)
vecQB=(x-1, y+5)
vecQC=(x-7, y+5)
vec0=(0, 0)

so, vecQA +vecQB +vecQC =vec0 is equivalent to

x-3 +x-1+x-7 =0, and y+2+y+5+y+5=0 so 3x-11=0 implies x=11/3
and 3y+12=0 implies y=-12/3

finally the the coordinates of point Q is (11/3, -4)

Use the "rule of 72" to estimate the doubling time (in years) for the interest rate, and then calculate it exactly. (Round your

bonufazy [111]

Answer:

Using the rule of 72, the doubling time is 9.35 years.

The exact answer is that the doubling time is 8.89 years.

Step-by-step explanation:

By the rule of 72, we have that the doubling time D is given by:

$D = \frac{72}{Interest Rate}$

The interest rate is in %.

In our exercise, the interest rate is 7.7%. So, by the rule of 72:

$D = \frac{72}{7.7} = 9.35$ .

Exact answer:

The exact answer is going to be found using the compound interest formula(since the rule of 72 is a simplification of this formula).

The compound interest formula is given by:

$A = P(1 + \frac{r}{n})^{nt}$

Where A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit t and t is the time the money is invested or borrowed for.

So, for this exercise, we have:

We want to find the doubling time, that is, the time in which the amount is double the initial amount, double the principal.

$A = 2P$

$r = 0.077$

There are 52 weeks in a year, so $n = 52$

$A = P(1 + \frac{r}{n})^{nt}$

$2P = P(1 + \frac{0.077}{52})^{52t}$

$2 = (1.0015)^{52t}$

Now, we apply the following log propriety:

$\log_{a} a^{n} = n$

So:

$\log_{1.0015}(1.0015)^{52t} = \log_{1.0015} 2$

$52t = 462.44$

$t = \frac{462.44}{52}$

$t = 8.89$

The exact answer is that the doubling time is 8.89 years.

olasank [31]

If 40% of students prefer keyboarding, 40/100*40=16 students like it best. If the remaining students prefer English, then 40-16=24 students like English best. Since 24 is more than 16, most students prefer English.
