Answer:

28 m

Step-by-step explanation:

The top angle in the triangle = 90° - 62° = 28°

Using the cosine ratio in the right triangle

cos28° = \frac{adjacent}{hypotenuse} = \frac{25}{x}

cross- multiply

x × cos28° = 25 ( divide both sides by cos28° )

x = \frac{25}{cos28} = 28.31425... ≈ 28 m

Thus the distance from the top to the crocodile is 28 m

Answer:

28.31 m to the nearest cm.

Step-by-step explanation:

Note the angle next to the crocodile measures  62 degrees ( alternate angles).

The required distance is the hypotenuse of the triangle and the  height 25m is the opposite side to the angle of  62 degrees..

Therefore we have sin 62 = 25 /x  where x is the distance required.

x = 25 / sin 62

= 28.31 m.

Which point-slope equation represents a line that passes through (3,-2) with a slope of -4/5?
Viefleur [7K]

Answer:

y + 2 = -4/5 (x - 3)

Step-by-step explanation:

y - y1 = m (x - x1). Put in your points for y1 and x1, and always remember to flip your signs.

unfortunately, I don't know why that isn't one of your answers, so sticking with the positive 2 I would choose y+2=- (- 3) if I were you. Looks like the -4/5 disappeared somehow?

Hope this helps

Jerry has taken a random sample of students and determined the number of electives that each student in his sample took last yea
loris [4]
The sample proportion of the the students that took fewer than the mean number of electives is given by the number of people who took less that the mean number of electives (i.e. 7.63) divided by the total number of students in the sample (i.e. 19). The total number of people who took less than 7.63 electives is 10. Therefore, the required sample proportion is 10 / 19.

wlad13 [49]
The sum of two numbers 5.036.
first number: one number has 4 in the tenths place, 7 in the thousandths place.
=> x.4x7
2nd number: 1 in ones place and 2 in the hundredths place.
=> 1.x2x
Now, we have the 2 numbers with given clues:
=> x.4x7 + 1.x2x, where x is the missing number.
Note that in adding numbers, we start from the right most.
=>x.4x7 + 1.x2x = 5.036
=> x.4x7 + 1.x29
=> x.407 + 1.x29
=> x.407 + 1.629
=> 3.407 + 1.629
=> 5.036
