Answer: 1967

Step-by-step explanation:

Ada was 15 years when her sister Ngozi was 18 years.

This means that Ngozi is older than Ada by:

= 18 - 15

= 3 years

If Ngozi is older by 3 years, this means that she must have been born 3 years earlier than Ada

If Ada was born in 1970, Ngozi was born:

= 1970 - 3

= 1967

Solve for x. 3^x−1=9^x+2 <br> Enter your answer in the box.
slava [35]

Answer:

-5 =x

Step-by-step explanation:

3^(x-1) = 9^(x+2)

Replace 9 with 3^2

3^(x-1) = 3^2^(x+2)

We know that a power to a power means the powers are multiplied

a^b^c = a^(b*c)

3^(x-1) = 3^(2x+2)

When the bases are the same, the powers have to be the same

x-1 = 2x+4

Subtract x from each side

x-x-1 =2x-x+4

-1 =x+4

Subtract 4 from each side

-1-4 =x+4-4

-1-4 = x

-5 =x

Malcolm ran the 440-yard and the 220-yard dash at a track meet.There are 3 in one yard. How many total feet did Malcolm run?Esti
Tresset [83]

For this case we have the following conversions:

1 yard = 3 feet

The estimate distance Is:

400yd = 1200feet

200yd=600 feet

Ten, the estimate Is:

1200 + 600 = 1800 feet

The real distance Is:

The total distance in yards is given by:

440 + 220 = 660 yd

Then, let's transform this distance to feet, with the given conversion:

660 * 3 = 1980 feet

The distance traveled is reasonable for a person

Comparing the estimate and the actual answer, the distance malcom Ran Is reasonable.

Answer:

Malcolm ran 1980 feet.

The distance is reasonable.

Compute the missing data in the table for the following exponential function f (x) = (one-fourth) Superscript x.
aliina [53]

Answer:

F(4) = \frac {1}{256}

Step-by-step explanation:

Given the following mathematical function;

F(x) = \frac {1}{4^{x}}

<u>When x = 1</u>

F(1) = \frac {1}{4^{1}}

F(1) = \frac {1}{4}

<u>When x = 2</u>

F(2) = \frac {1}{4^{2}}

F(2) = \frac {1}{4*4}

F(2) = \frac {1}{16}

<u>When x = 3</u>

F(3) = \frac {1}{4^{3}}

F(3) = \frac {1}{4*4*4}

F(3) = \frac {1}{4*4*4}

<u>When x = 4</u>

F(4) = \frac {1}{4^{4}}

F(4) = \frac {1}{4*4*4*4}

F(4) = \frac {1}{256}

<u>When x = 5</u>

F(5) = \frac {1}{4^{5}}

F(5) = \frac {1}{4*4*4*4*4}

F(5) = \frac {1}{1024}
