1. Ernie Boddy had $3,620.00 on deposit at savings bank on July 1. The money earns interest at a rate of 6.5% compounded quarterly. a. What is the amount in the account on April first of the following year if no deposits or withdrawals were made? B. How much is the compound interest?​

Answers

Answer:

235.3$ for part a

The amount in the account on April first of the following year is $3799.358 and the compound interest is $179.358.

What is Compound Interest?

Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.

(a) The amount in a compound interest can be found as,

A = P(1 + [tex]\frac{r}{n}[/tex]) ^(nt)

where A is the final amount, P is the initial or principal amount, r is the interest rate, n is the number of times compounding occurs in a year and t is the number of years.

Given P = $3,620, r = 6.5% = 0.065, t = 9 months = 0.75 year

n = 4 (since compounded quarterly)

A = 3620 (1 + [tex]\frac{0.065}{4}[/tex]) ^(4 × 0.75)

  = 3620 (1.01625)³

  = 3799.358

(b) Compound Interest = Final amount - Initial amount

                                      = 3799.358 - 3,620

                                      = $179.358

Hence the compound interest is $179.358.

Find the surface area of a square pyramid with side length 5 ft and slant height 7 ft.
5 ft
5 ft

Answers

Answer:

99.33ft^2

Step-by-step explanation:

The surface area of a square pyramid is expressed as;

TSA = a²+2a√a²/4 + h²

Given that

a = 5ft

h = 7ft

Substitute

TSA = 5²+2(5)√5²/4 + 7²

TSA = 25+10√25/4 + 49

TSA = 25 + 10√(221/4)

TSA = 25 + 10(√55.25)

TSA = 25 + 10(7.433)

TSA = 25 +  74.33

TSA = 99.33ft^2

Hence the surface area of a square pyramid with side length 5 ft and slant height 7 ft is 99.33ft^2

Answer:5x5=25 fts

4(1/2 x 5ft x7 ft) = 70 fts

Newton's Law of Cooling states that the rate of change of the temperature of an object, T, is proportional to the difference of T and the temperature of the region, TR or dT over dt equals k times the quantity T minus T sub R end quantity. An object with core temperature of 1200°F is removed from a fire and placed in a region with a constant temperature of 80°F. After 1 hour, its core temperature is 830°F. What is the object's core temperature 4 hours after it is taken off the fire?

Answers

Answer:

- 278.4°F

Step-by-step explanation:

Temperature of Object ( T ) = 1200° F

Temperature of surrounding ( M ) = 80°F

Time ( t ) = 1 hour

dT / dt  ∝ ( M - T )

dT /dt ∝ | ( 80 - 1200 ) |

dT / dt = k ( 1120 )

(1200 - 830 ) / 1 = k ( 1120 )

hence k =  ( 1200 - 830 ) / 1120

              =   370 / 1120 = 0.33

what is the object's temperature (x )after 4 hours

( 1200 - x ) / 4  = 0.33 ( 1120 )

( 1200 - x ) / 4 = 369.6

hence x = 1200 -  ( 4 * 369.6 )

              = - 278.4 ° F

Answers

Answer:

m<X = [tex]126^{o}[/tex]

Step-by-step explanation:

From the given isosceles triangle, we have;

<W and <V as the base angles

So that,

m<W = m<V = 27 (base angles of an isosceles triangle are equal)

Thus,

m<X + m<V + m<W = 180 (sum of angles in a triangle)

m<X + 27 + 27 = 180

m<X + 54 = 180

m<X = 180 - 54

       = 126

m<X = [tex]126^{o}[/tex]

  q = 9

Step-by-step explanation:

The angle bisector divides the triangle sides proportionally.

  q/36 = (16 -q)/28

  7q = 9(16 -q) . . . . . . multiply both sides by 252 (the LCM of 28 and 36)

  16q = 16(9) . . . . . . . . add 9q to both sides

  q = 9 . . . . . . . . . . . . . divide by 16

Additional comment

We are given the sum of the segment lengths on the far left side. The proportion is the same for the sum of sides as it is for individual sides.

  (q/36) = 16/(36+28)

  q/36 = 16/64 = 1/4

  q = 36/4 = 9

In ΔDEF, the measure of ∠F=90°, the measure of ∠D=20°, and EF = 92 feet. Find the length of FD to the nearest tenth of a foot.

By applying tangent rule in the given right triangle,

tan(20°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

tan(20°) = [tex]\frac{EF}{FD}[/tex]

0.36397 = [tex]\frac{92}{FD}[/tex]

You can describe this in terms of foot-pounds. For example, you want to calculate the energy used to tighten a nut when using a wrench, or to lift a weight from the floor. Mechanical force takes place in time, so to describe the power requirement, you use foot-pounds per second.
