Answer:

angle of depression = 59.04 degrees

Step-by-step explanation:

tangent X = 30/50

tangent X = 0.6

Consider the numbers 4/15 and 3/10 (a) Compare the numbers. (B) find a fraction between the two given numbers
valentinak56 [21]
As a decimal 4/15 = 0.2666667
As a decimal 3/10 = 0.3 [talk about close]
3/10 is bigger.

You could take an average to find something between 4/15 and 3/10
1/2(4/15 + 2/10)
1/2(8/30 + 6/30)
1/2(14/30)
1/2(7/15)
7/30 is between the two given numbers..

Jay took a number, n, and increased it by 25%. Then, he doubled the resulting product. Which of the following is equivalent to t
ruslelena [56]

Answer: Multiplying the number by 2.5

Step-by-step explanation:

Jay took a number, n, and increased it by 25%. The value gotten will be:

= n + (25% × n)

= n + (0.25 × n)

= n + 0.25n

= 1.25n

After that, Then, he doubled the resulting product. The value now gotten will be:

= 2 × 1.25n

= 2.50n

Therefore, the equivalent will be multiplying the number by 2.5. This will be:

= n × 2.5

= 2.5n

Therefore, it's thesame with the value gotten.

The correct option is D.

Using f(x) = 4x + 6 with a domain of {-1, 0, 2 }, find the range.
lianna [129]

Answer:

{2, 6, 14}

Step-by-step explanation:

Using f(x) = 4x + 6 with a domain of {-1, 0, 2 }, find the range.

To get the range, we will substitute the values of the domain into the given function as shown;

when x = -1

f(-1) = 4(-1)+6

f(-1) = -4+6

f(-1) = 2

when x = 0

f(0) = 4(0)+6

f(0) = 0+6

f(0) = 6

when x = 2

f(2) = 4(2)+6

f(2) = 8+6

f(2) = 14

Hence the required range are {2, 6, 14}
