Drag and drop numbers into the boxes so that the paired values are in a proportional relationship.

Answer:

A=6 and B=4.5

Step-by-step explanation:

You are given table

\begin{array}{cccccc}x&2&4&[A]&7&9\\y&1&2&3&3.5&[B]\end{array}

If the paired values are in a proportional relationship, then

\dfrac{2}{1}=\dfrac{4}{2}=\dfrac{[A]}{3}=\dfrac{7}{3.5}=\dfrac{9}{[B]}.

Note that

\dfrac{2}{1}=\dfrac{4}{2}=\dfrac{7}{3.5}=2,

then

\dfrac{[A]}{3}=2\Rightarrow [A]=6,\\ \\\dfrac{9}{[B]}=2\Rightarrow [B]=\dfrac{9}{2}=4.5.

What is numerical expression?<br> Three less than 11 times the sum of 9-2
sweet-ann [11.9K]

Answer:

11(9 - 2) - 3

Step-by-step explanation:

This is how you write the expression.

Three less means we have a -3.

11 times the sum of 9 - 2 means we have 11(9 - 2)

We put these together to get:

-3 + 11(9 - 2)

Or we can simplify it to:

11(9 - 2) - 3

Which of the following is equivalent to sec2θ−1sec2θ for all values of θ for which sec2θ−1sec2θ is defined?
galina1969 [7]

Answer:

2 sin^2 \theta

Step-by-step explanation:

According to the scenario, the following information is given:

= \frac{sec^2 \theta - 1 }{sec^2 \theta}

= (\frac{1}{\frac{cos^2\theta}{\frac{1}{cos^2\theta} }} - 1)

= 1 - cos^2\theta\\\\= 1 - (1 - 2 sin^2 \theta)\\\\= 2 sin^2 \theta

Therefore for the given equation, the answer is 2 sin^2 \theta

Which exponential function grows at a faster rate than the quadratic function for zero is less than X is less than three
Ann [662]

Answer:

43.35 years

why?

From the above question, we are to find Time t for compound interest

The formula is given as :

t = ln(A/P) / n[ln(1 + r/n)]

A = $2500

P = Principal = $200

R = 6%

n = Compounding frequency = 1

First, convert R as a percent to r as a decimal

r = R/100

r = 6/100

r = 0.06 per year,

Then, solve the equation for t

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(2,500.00/200.00) / ( 1 × [ln(1 + 0.06/1)] )

t = ln(2,500.00/200.00) / ( 1 × [ln(1 + 0.06)] )

t = 43.346 years
