You are buying a house and will borrow $330,000 on a 25-year fixed rate mortgage with monthly payments to finance the purchase. Your loan officer has offered you a mortgage with an APR of 4.15 percent. Alternatively, she tells you that you can “buy down” the interest rate to 3.8 percent if you pay points up front on the loan. A point on a loan is 1 percent (one percentage point) of the loan value. How many points, at most, would you be willing to pay to buy down the interest rate? (Do not round intermediate calculations and round your answer to 3 decimal places, e.g., 32.161.)

[tex]8^{15[/tex]

Step-by-step explanation:

Hello!

Use exponent rule: [tex]a^b * a^c = a^{b + c}[/tex]

Use the rule to simplify the exponential expression.

The simplified form is [tex]8^{15[/tex].

The exponential equation to model this after t time periods is:

N(t) = 10 ( 1/2 ) [tex]^\frac{t}{30}[/tex]

Given,

Melatonin is fast-acting and has a half-life of approximately 30 minutes.

10-milligram tablet is taken.

We need to write an exponential equation to model this after t time periods.

Half-life is the time required for a quantity to reduce to half of its initial value.

The formula is given as:

N(t) = [tex]N_{0} ~(\frac{1}{2})~^\frac{t}{t_{1/2}}[/tex]

Where

N(t) = quantity of the substance remaining

[tex]N_{0}[/tex] =  initial quantity of the substance

[tex]t_{1/2}[/tex] = half-life of the substance

We have,

Half-life = 30 minutes

[tex]N_{0}[/tex] = 10 mg

The exponential equation to model this after t time periods is:

N(t) = 10 ( 1/2 ) [tex]^\frac{t}{30}[/tex]

Thus the exponential equation to model this after t time periods is:

N(t) = 10 ( 1/2 ) [tex]^\frac{t}{30}[/tex]

Answer:

Step-by-step explanation:

Given an oval track in the shape of a 48 m by 96 m rectangle with semicircular ends, you want the length of the track and the area enclosed.

If you remove the rectangle, you see that what remains is a circle of diameter 48. The length of that circular portion of the track is the circumference of the circle:

  C = πd

  C = π(48 m) = 48π m ≈ 151 m

Added to that length are the two 96 m sides of the rectangle. So, the total length of the track is ...

  track length = curved length + straight length

  track length = 151 m + 2×96 m = 343 m

The length of the track is 343 meters.

The area enclosed by the track includes the area of the circle we saw above, and the area of the rectangle.

The radius of the circular portion is half the diameter, or 24 m. Then the area is ...

  A = πr²

  A = π(24 m)² = 576π m² ≈ 1810 m²

The area of the rectangular portion is the product of length and width:

  A = LW

  A = (96 m)(48 m) = 4608 m²

The enclosed area is the sum of these areas:

  enclosed area = area of circle + area of rectangle

  enclosed area = 1810 m² +4608 m² = 6418 m²

The area enclosed by the track is 6418 square meters.

The length (perimeter) of the track is approximately equal to 342.796 meters and the area enclosed by the track is approximately equal to 6417.557 square meters.

In this problem we have a composite figure generated by a rectangle and two semicircles, of which we must determine its perimeter and area. The perimeter is the sum of the contour lengths of the semicircles and the rectangle and the enclosed area is the sum of areas of the two semicircles and a rectangle.

The perimeter of the composite figure is:

p = 2π · r + 2 · l

p = 2π · (24 m) + 2 · (96 m)

p ≈ 342.796 m

A = π · r² + l · (2 · r)

A = π · (24 m)² + (96 m) · (48 m)

A ≈ 6417.557 m²

The length (perimeter) of the track is approximately equal to 342.796 meters and the area enclosed by the track is approximately equal to 6417.557 square meters.

Step-by-step explanation:

if I understand you correctly, then we have the 4 described cards. 3 of these 4 cards are face cards (Jack, Queen, King).

a probability is always desired cases over totally possible cases.

so, for the first pull we have a probability of

3/4 = 0.75

we have 4 total possibilities, and 3 of them are the desired outcome.

for the second pull we have then only 3 cards left (we did not replace the first pulled card). and because the first pulled card was in this scenario a face card, 2 out of these 3 cards are face cards.

so, the probability to pull a face card here is

2/3 = 0.66666...

when we combine these 2 events into one connected event (we are creating event 1 AND event 2), we multiply the probabilities, giving us

3/4 × 2/3 = 6/12 = 1/2 = 0.5

In a triangle of EFG we have ∠E+∠F = 120°,E=(8x-2)° and F=(7x+2)°.

Option B is true and angle of G is 60°.

Given that,

∠E+∠F = 120°

In the figure we have a triangle with EFG.

E=(8x-2)°

F=(7x+2)°

We know

∠E+∠F = 120°

8x-2+7x+2=120

15x=120

x=120/15

x=8

We got x =8

∠E=8[tex]\times[/tex]8-2=62°

∠F=7[tex]\times[/tex]8+2=58°

Now, we know in a triangle all angles are equal to 180°.

∠E+∠F+∠G=180°

62°+58°+G=180°

120°+G=180°

G=180°-120°

G=60°

We have 4 option

a) (7x)° which is false

b) (7x+4)° which is true (7[tex]\times[/tex]8+4=60°)

c)(8x)° which is false

d) (8x+4)° which is false

Answer:

x = 10/9

Step-by-step explanation:

Solve:

27^(3x-2) = 81

When solving equations in exponential form make sure the two bases on both sides are the same.

3^3(3x-2) = 3^4

Once the two bases are the same you cancel them out and used its exponent to solve the equation.

3(3x-2) = 4

9x-6 = 4

Add 6 to both sides.

9x-6+6 = 4+6

9x = 10

Divide both sides by 9.

x = 10/9

Therefore x = 10/9.

The coordinates of B is (-5, 6).

In geometry, a coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space

The total distance travelled by the body is 48 meters

According to the question we have been given an equation of the position of  a body moving along x-axis as

                    s = t³ - 12t² + 36t

where,    s = distance in meters

             t = time in seconds

We need to find the total distance traveled by the body from t=0s to t=4s

The formula for the total distance is given as :

            S = |s(1) - s(0)| + |s(2) - s(1)| + |s(3) - s(2)| + |s(4) - s(3)|

Now we will find out the distance travelled in time 0s to 4s

when t = 0s ,  s = (0)³ - 12(0)² + 36*0

                         = 0m

         t = 1s ,  s = (1)³ - 12(1)² + 36*1

                         =  25m

         t = 2s ,  s = (2)³ - 12(2)² + 36*2

                         =  32m

         t = 3s , s = (3)³ - 12(3)² + 36*3

                         = 27m

         t = 4s , s = (4)³ - 12(4)² + 36*4

                         = 16m

Putting the required values in the above formula we get ,

  S = |25-0|+|32-25|+|27-32|+|16-27|

  S = 25 + 7 + 5 + 11 meters

   S = 48 meters

Hence the total distance travelled by the body is 48 meters

Profit is a residual income, It is the gain amount from any kind of business activity. In short, if the selling price (SP) of the product is more than the cost price (CP) of a product, then it is considered as a gain or profit. while return is a total revenue. Profits may be negative, whereas returns, such as wages and interest are always positive.

amount invested in Fund A = $12,000            (given)

profit returned by Fund A =  1% of $12,000    (given)

= 1/100*$12,000

= $120

Let amount invested in Fund B = x                   (assumption)

profit returned by Fund B =  6% of x                 (given)

= 6/100*x

= $ 6x/100

Given that both funds A and B together returned a 3% profit, So the equation we get is

120+6x/100 = 3% of (12,000+x)

(12,000+6x)/100 = 3/100* (12,000+x)

12,000+6x = 3(12,000+x)

12,000+6x = 36,000+3x

6x-3x = 36,000-12,000                       (bringing like terms on same side)

3x = 24,000
