350 divided into 20 is 170 with a remainder of 10

250/20 =12 r10 when you divide 250 by 20 you will get 12 r10 because 20 cannot go into 2 but it can go into 25 so u place a 1 over the five because 1 goes into 25 once then subtract 25 from 20 and u will get 5. since 20 cant go into 5 bring the 0 down and it will become 50. 20 cant go into 50, 2 times so subtract 50 from 40 and u will get a remainder of 10 and since 20 cant go into 10 and there is nothing else to bring down the remainder is 10

A man, 1.5m tall, is on top of a building. He observes a car on the road at an angle of 75°. If the building is 30m, how far is

kolbaska11 [484]

Answer:

The answer to this question is 8.44 m.

Step-by-step explanation:

This problem is best illustrated in the photo below.

First, we must know that the angle stated in the problem is the angle of depression. Angle of depression is the angle between the horizontal and the line of sight of the observer. On the other hand, if the observer is looking upward, then the angle between the horizontal and his line of sight is called the angle of elevation.

Since we have the given angle of depression, we must use its complementary angle to solve for the distance of the car from the building.

Let x = complementary angle of 75°

y = distance of the car from the building

To solve for x,

To solve for y, we need to use a trigonometric function that will relate the adjacent of 15° and the opposite of 15°. Let us look at the mnemonics

SOH: Sine =

CAH: Cosine =

TOA: Tangent =

Therefore we must use the tangent function to solve for y.

Please help me i would really appreciate it

So the first thing that happens here is that the triangle is rotated 90 degrees clockwise. This can be seen because it is rotated, then you also notice that the triangle is reflected across the y axis.

F(x)=−6x+7, evaluate f(x+2)

lakkis [162]

Answer:

f(x+2) = - 6x - 5

Step-by-step explanation:

As we have f(x) =- 6x + 7, then we also have f(x+2) = - 6(x+2) + 7 = - 6x - 12 + 7 = - 6x - 5.

If y = x 2 - 4 is being graphed using the table method, what is the y-value generated when x = - 2 ?

Arada [10]

Answer:

(There's a confusion here, is x 2 x times 2? The answer and explanation are based on x multiply by 2)

y = -8

Step-by-step explanation:

Substitution Method-

y = x 2 - 4

x = -2

y = (-2) 2 - 4

PEMDAS - parentheses; exponents; Multiplication & Division; Addition & Subtraction

we are going to multipl -2 and 2 together ---> -4

y = -4 - 4

Same sign add, different sign subtract.

Same sign keep the sign, different sign keep the larger.

y = -8

Hope this helps!

Thank you,

Have a great day!
