Answer:

the answer is 1430 in military time

Step-by-step explanation:

Step-by-step explanation:

Since this is a right triangle and we are given an angle measure that measure 45, the other angle measure also measure 45.

So this means we are dealing with a 45-45-90 triangle.

A 45-45-90 triangle legs are equal to each other and the hypotenuse measures sqr root of 2 times more than the legs.

The hypotenuse measure 2 times sqr root of 14 so divide by sqr root of 2 to find x and y.

[tex] \frac{2 \sqrt{14} }{1} \times \frac{1}{ \sqrt{2 } } = \frac{ \sqrt{56} }{ \sqrt{2} } = \sqrt{28} = 2 \sqrt{7} [/tex]

Since x and y are equal, they both measure

[tex]2 \sqrt{7} [/tex]

Answer:

tan(E) =[tex]\sqrt{3\\}[/tex]

Step-by-step explanation:

Given: ED = 4[tex]\sqrt{6}[/tex]   and   CD = 6[tex]\sqrt{2\\}[/tex]

Step 1 : Find CE

ED² = CE² + CD²

(4√6)² = (CE)² + (6√2)²

96 = CE² + 72

24 = CE²

CE = 2√6

Step 2 : Find ∠E using side lengths

Based on our leg lengths : 6√2   &   2√6 , we can conclude that this is a

30-60-90 triangle (the sqaures are opposites yk)

Because 6√2 is the larger leg, and ∠E is opp side of CD,

∠E = 60

From there all you do is find the tangent with a calculator "tan(60)"

Answer: d

Step-by-step explanation:

t= b1- B0/ SE(b1) = 2.37-0/0.65= 3.646 -> 3.65

The closest value of the test statistic for the hypothesis test is 3.65 if the least-squares regression line to be Rˆ=126+2.37T option (d) is correct.

A regression line is a graph that illustrates the pattern of a group of statistics. In other words, it shows the data's best pattern.

We have a least-squares regression line to be:

R^ = 126+2.37T

A hypothesis test was conducted to investigate whether there is a linear relationship between maximum daily temperature and the daily revenue from salmon sales.

Using a T-test to find the significance of the slope coefficient is measured:

[tex]\rm t = \frac{b}{SE}[/tex]

Here SE = 0.65

b = 2.37

Put this value in the above expression, we get:

[tex]\rm t = \frac{2.37}{0.65}[/tex]

t = 3.6461   or

t = 3.65

Thus, the closest value of the test statistic for the hypothesis test is 3.65 if the least-squares regression line to be Rˆ=126+2.37T option (d) is correct.

Answer:

Step-by-step explanation:

the area of the circle is 40.8407 in^2

Answer:

1 8x-6

2 3

3 7s -10

9514 1404 393

Answer:

Step-by-step explanation:

For a quadrilateral in which the diagonals cross at right angles, such as a rhombus or kite, the area can be found as half the product of the diagonals.

For the purpose here, we can ignore the factor of 1/2, which is the same for both, and simply consider the products of the diagonals.

Kite A has an area proportional to (30 in)(30 in) = 900 in².

Kite B has an area proportional to (20 in)(40 in) = 800 in².

Kite A has a larger area, so will use more paper.

__

Only Rudy knows why he chose answer C. Perhaps he guessed, rather than doing any math.

Answer:

A. Kite A

Step-by-step explanation:

To determine which of the two kites will use need more paper to make, find the area of each kite.

Kite A:

Area = (d1*d2)/2

d1 = 30 in.

d2 = 30 in.

Area of kite A = (30*30)/2 = 450 in.²

Kite B:

Area = (d1*d2)/2

d1 = 20 in.

d2 = 40 in.

Area of kite B = (20*40)/2 = 400 in.²

✅Kite A will use more paper to make because it has a greater area of 450 in.² than Kite B (400 in.²).

So, Ruby was wrong. He most likely didn't calculate the area of both kites correctly.

[tex] = \frac{7}{0} [/tex]

(undefined)

Notice that the two points have the same x-coordinate of 1. This means that the line is a vertical line, and vertical lines have undefined slopes.

Answer:

Undefined slope

Step-by-step explanation:

(1, 4) and (1, −3)

Slope:

m=(y2-y1)/(x2-x1)

m=(-3-4)/(1-1)

m=(-7)/0

When 0 is the denominator, there's no slope since it's undefined.

Step-by-step explanation:

Q1 .  

Money saved every month = $200  

Time period until you retire = 35 years

Rate of Interest = 8%

The money is compounded monthly.

a). Amount for retirement = Saving annuity

Saving or making  a series of payments at regular intervals is called annuity.

Annuity formula is :

P_{n} = d((1 + r/k)^{nk} - 1)/(r/k)

PN is the balance in the account after N years.

d is the regular deposit (the amount you deposit each month)

r is the annual interest rate in decimal form(R/100)

k is the number of compounding periods in one year

Here d= $200 , r = 0.08 , n = 35 years , k = 12 (compounded monthly)

P_{n} = 200((1 + 0.08/12)^{(35*12)} - 1)/(0.08/12)

= $ 458776.50

b). Looking at the formula used in above option we can -

Increase number of years to increase retirement amount

Increase the monthly amount deposited

Increasing rate of interest also increases the amount

Compounding Annually , half yearly or quaterly will decrease the amount

c). Let us change the amount from $200 to $300 . Then amount will be

P_{n} = d((1 + r/k)^{nk} - 1)/(r/k)

P_{n} = 300((1 + 0.08/12)^{(35*12)} - 1)/(0.08/12)

= $ 688164.75

Answer:

$ 28,665.11 must be deposited today into the account.

Step-by-step explanation:

Given that there is an account with monthly compounding and an APR of 4%, to determine how much must be deposited today into the following account in order to have $ 35,000 in 5 years, the following calculation must be performed:

X x (1 + 4/12) ^ 5x12 = 35,000

X x (1 + 0.333) ^ 60 = 35,000

X x (1,333) ^ 60 = 35,000

X x 1.220999 = 35,000

X = 35,000 / 1.22099

X = 28,665.11

Thus, $ 28,665.11 must be deposited today into the account.
