Answer:

Point (2, 20) does not lie on the given curve.

Step-by-step explanation:

Let us see explanation:

f(x) = 2. \:  {5}^{x}  \\  \\  \therefore \: f(x) \: at \: x = 2 \\ f(2) = 2. {5}^{2}  = 2.25 = 50 \\  \\ hence \: at \: x = 2 \:  \: f(x) = 50 \\  \therefore \:point (2 \:  \: 20) \: does \: not \: lie \: on \: the \: \\   \:  \:  \:  \:  \: curve.

Answer:

(2, 20) is not on the curve.

Step-by-step explanation:

When x = 3,  f(x) =  2*5^3 = 250 .  So (3, 250) is on the curve.

When x = 1, f(x) = 2*5^1 = 10 .  So (1, 10) is on the curve.

When x = 2, f(x) =  2*5^2 = 50 .   So (2, 50) is on the curve.

From the last line we see that (2, 20) is NOT  on the curve.

What’s the answer to number 4 ?
Marizza181 [45]

Answer:

4.36*10^-^1

Step-by-step explanation:

Given:  

             (3.6*10^-^2)+(4.0*10^-^1)

Make the power of '10' equal by shifting the decimal place of any one value.

                (0.36*10^-^1)+(4.0*10^-^1)

Taking the '10^-^1' common

               10^-^1*(0.36+4.0)

Adding the values in the bracket gives:

                      4.36*10^-^1

Please help me with my question!!
Dmitrij [34]

The question is unclear but I will assume they mean 1/4 and 3 1/2.

Find common denominators.

1/4

3 1/2 -> 3 2/4

Turn into an improper fraction.

3 2/4 -> 14/4

Divide.

14/4 / 1/4

14/4 * 4/1

56/4

14

So, they can make 14 ornaments.

Best of Luck!

Which is equivalent to sin^-1(.75)
Neko [114]
<h2>Answer: 0.85 radians</h2>

Step-by-step explanation:

We have the following trigonometric expression:

sin^{-1}(0.75)=arcsin(0.75)

The result of this calculation is:

sin^{-1}(0.75)=48.59\° where the angle is in degrees

If 360\°=2\pi rad then:

48.59\°(\frac{2\pi rad}{360\°}=0.848 rad \approx 0.85 rad  

Therefore the answer is 0.85 radians
