I believe it is a function. An inequality you would need signs like (<, or >), and an equation you need an equal sign. so the only logical answer is a function.

MakcuM [25]

Answer:

B. 9.66

Step-by-step explanation:

To find how high the kite is off the ground, we will follow the steps below;

we will use trigonometric ratio to solve the problem. That is;

SOH CAH TOA

sinФ = opposite / hypotenuse

cosФ = opposite / hypotenuse

tanФ = opposite / adjacent

from the diagram below

Ф = 25°

opposite = x

adjacent = 10 feet

The best trig ratio to use is tan

we can now proceed to insert the values into the formula

tanФ = opposite / adjacent

tan 25° = $\frac{x}{10}$

cross-multiply

x = 10 tan25°

x ≈4.66 feet

height of the kite off of the ground = x + height of Alice

=4.66 + 5

=9.66 feet

Therefore, the kite is 9.66 feet high off of the ground

Problem: Express the following numbers in standard form:

Andrews [41]

Answer:

(i) 8.5 × 10^-12

(ii) 9.42 × 10^-12

(iii) 602 × 10^15

(iv) 8.37 × 10^-9

(v) 3.186 × 10^10

Step-by-step explanation:

(i) 0.0000000000085

= 0.0000000000085 × 10^12/10^12

= 8.5/10^12

= 8.5 × 10^-12

(ii) 0.00000000000942

= 0.00000000000942 × 10^12/10^12

= 9.42/10^12

= 9.42 × 10^-12

(iii) 6020000000000000

= 602 × 10^15

(iv) 0.00000000837

= 0.00000000837 × 10^9/10^9

= 8.37/10^9

= 8.37 × 10^-9

(v) 31860000000

= 3.186 × 10^10
