Answer:

k = 42

Step-by-step explanation:

That's a right angle, indicated by the square. A right angle is 90 degrees.

To find $(k+1)$ , we need to subtract 47 from 90. 90 - 47 = 43.

To find k, we subtract 1 on both sides. k = 42.

. The function s(l) = 1.34 √l models the maximum speed s in knots for a sailboat with length l in feet at the waterline. a. Use

trasher [3.6K]

Answer:

The length of the sailboat is 80 feet.

Step-by-step explanation:

The function

$s(l) = 1.34 \sqrt{l}$ ................ (1)

models the maximum speed s in knots for a sailboat with length l in feet at the waterline.

So, using this model we have to find the length of a sailboat with a maximum speed of 12 knots.

Now, from equation (1) we get

$12 = 1.34 \sqrt{l}$

⇒ $\sqrt{l} = 8.955$

⇒ $l = (8.955)^{2} = 80$ feet (Answer)

{The value is round to the nearest foot}

Question is down below, best answer gets Brainliest! Good luck!

Westkost [7]

Answer:

976cm^2

Step-by-step explanation:

Surface area:

Ara of cross section x 2 = 1/2 x 2 x 14 x 24 = 14 x 24 = 336

Area of base = 14 x 10 = 140

area of slope x 2 = 25 x 10 x 2 = 500

Total surface area = 500+140+336 = 640 + 336 = 973cm^2

Volgvan

Answer:

Step-by-step explanation:

Subtract the y values and put them in the numerator (top of fraction). 9-4=5.

Subtract the x values and put them in the denominator (bottom) 5-0=5.

Put the numbers in the fraction and simplify. 5/5 = 1.

Which data set has the greatest spread for the middle 50% of its data?

Sindrei [870]

Answer:

The answer is (c) {13, 17, 12, 21, 18, 20}.

Step-by-step explanation:

The given data sets are:

{18, 13, 22, 17, 21, 24},

{17, 19, 22, 26, 17, 14},

{13, 17, 12, 21, 18, 20}

and

{18, 21, 16, 22, 24, 15}.

To find the greatest spread for the middle 50%, we need to find the Interquartile range for all the data sets and check which one is highest.

For first set, Interquartile range (IQR) = 22 - 17 = 5.

For second set, IQR = 22 - 17 = 5.

For third set, IQR = 20 - 13 = 7

and

for fourth set, IQR = 22 - 16 = 6.

Since IQR is highest for the third data, so the correct option is (c) {13, 17, 12, 21, 18, 20}.

Hope it helps

Given f(x)=7x - 6 and g(x)=3x, what is f(3) - g(2)?

tino4ka555 [31]

Answer:

f(3) - g(2) = 9

Step-by-step explanation:

f(x) - g(x)

f(x) = 7x - 6

g(x) = 3x

7x - 6 - 3x

f(3) - g(2)

7(3) - 6 - 3(2)

21 - 6 - 6 = 15 - 6 = 9
