Answer:

5k

Step-by-step explanation:

The interest accrued on the principal is $100.

Using the formula;

A = P( 1 + r/n)^nt

A - amount

P - Principal

r = rate

n = Number of times the interest is compound

t = time in years

Substituting values;

A = 4,300( 1 + 0.023/365)365 × 1

A =  $4400

Interest =  $4400 - $4,300 = $100

The annual percentage yield is obtained from;

APY=100 (1 + r/n )n – 1

APY=100 (1 + 0.023/365)^n - 1

APY= 100(0.023)

APY= 2.3 %

Assuming the speed of car B to be x and the speed of car A to be x+20

156 = 208

x. x+20

156(x+20)= 208x

156x+3120=208x

3120=208x-156x

3120=52x

x=60

The speed of car A is (x)= 60

The speed of car B is(x+20)= 80

Answer:

Answer:

b = 12.6

Step-by-step explanation:

a*2 + b*2 = c*2

6*2 + b*2 = 14*2

36 + b*2 = 196

Subtract 36 from both sides

36 + b*2 = 196

-36             -36

b*2 = 160

Find the square root of both

b = 12.64911064  or 12.6

Answer:

AC = 12

Step-by-step explanation:

From the question, we have that BD is perpendicular to AC

This means that it is at 90 degrees to the base

so we have two similar right triangles

Let us use Pythagoras’ theorem to get the measure of one of the legs (AD and DC)

Let us call the leg x

We have the Pythagoras’ theorem stating that the square of the hypotenuse (the side facing the right angle; 10 here) is equal to the sum of the squares of the two other sides

10^2 = x^2 + 8^2

100 = x^2 + 64

x^2 = 100-64

x^2 = 36

x = √36

x = 6

AD = DC = 6

AC = 2 * AD

AC = 2 * 6

AC = 12

Answer:

18.6inches

Step-by-step explanation:

Given the length of a side of a pentagon to be 6 inches.

If this length is dilated by a factor of 3.1, the new length will be;

New length = Old length * dilation factor

New length = 6 * 3.1

New length = 18.6inches

Hence the length of each side of the dilated pentagon is 18.6inches

Answer:

So the answer is 2^-3

Step-by-step explanation:

The principle is the same no matter what the base.

Log_2 (7) + Log_2(3/28) - Log_2(6)

+ means multiply

- means divide

Log_2(7 * 3/28 /6)

Log_2(7/6 * 3/28)

Log_2(1/2 * 1/4)              3 divides into 6 twice. 7 divides into 28 four times

log_2 (1/8)

This is equivalent to 2^(-3)

Answer:

a₅₇ = 214

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₅ = 6 and a₉₂ = 354 , then

a₁ + 4d = 6 → (1)

a₁ + 91d = 354 → (2)

Subtract (1) from (2) term by term to eliminate a₁

0 + 87d = 348

87d = 348 ( divide both sides by 87 )

d = 4

Substitute d = 4 in (1) and solve for a₁

a₁ + 4(4) = 6

a₁ + 16 = 6 ( subtract 16 from both sides )

a₁ = - 10

Then

a₅₇ = - 10 + (56 × 4 ) = - 10 + 224 = 214

Answer:

b=8

Step-by-step explanation:

Perpendicular lines are negative and reciprocal; when you multiply the slopes together, the result is -1.

we are given the line y=-3x-5

we need to find the slope of the new line. To do that, we can use this equation:

-3m=-1

divide by -3 on both sides

m=1/3

so the slope of the perpendicular line is 1/3

We can write our line in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept, which is what we need

so far our equation is:

y=1/3x+b

we need to find b

we can substitute the point (-3,7) into the equation, since the line will pass through it to solve for b

so:

7=1/3(-3)+b

7=-1+b

8=b

so the y intercept of the line is 8; as a point it's (0,8)

hope this helps!
