Answer:

Option 2 and 5 are correct.

Step-by-step explanation:

We need to tell which one of them is quadratic function.

Option 1 is exponential decay so, it is not quadratic.

Option 2 is quadratic because the diver will take the parabolic shape when jumps.

Option 3 is not quadratic.Option 4 is not quadratic it is linear.

Option 4 is again exponential not quadratic.

Option 5 is quadratic because it takes the parabolic shape again.

Answer:

28 m
15 m
24.8 m
1.0 m

Step-by-step explanation:

The given statement is the scale factor:

$\dfrac{\text{scale distance}}{\text{actual distance}}=\dfrac{1\text{ cm}}{2\text{ m}}$

This can be rearranged to the formula ...

$\text{actual distance}=\text{(scale distance)}\dfrac{2\text{ m}}{1\text{ cm}}$

Filling in the given scale distances, you find the actual distances to be ...

$\textbf{(a) }(14\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=14\cdot2\text{ m}=28\text{ m}\\\\\textbf{(b) }(7.5\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=7.5\cdot2\text{ m}=15\text{ m}\\\\\textbf{(c) }(12.4\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=12.4\cdot2\text{ m}=24.8\text{ m}\\\\\textbf{(d) }(0.5\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=0.5\cdot2\text{ m}=1.0\text{ m}\\\\$

yarga [219]

Answer:

C) 45

Step-by-step explanation:

By Basic Proportionality Theorem:

$\frac{x}{18} = \frac{20}{8} \\ \\x = \frac{18 \times 20}{8} \\ \\ x = \frac{360}{8} \\ \\ x = 45$

Please I need help!!

Answer: X equals 8

Step-by-step explanation: figure OUTD is a rectangle. Each angle in a rectangle measures 90 degrees. Therefore we can derive the value of angle X by the following expression;

(7X + 2) + 4X = 90

7X + 2 + 4X = 90

11X + 2 = 90

Subtract 2 from both sides of the equation

11X = 88

Divide both sides of the equation by 11

X = 8.
