The sketches show the graphs y=-x^2+16 and y=7

Tanzania [10]

Answer:

7 = -x^2 +16

x^2 -16 = 7

x^2 -23 = 0

Using quadratic equation

x = -0 +- sqrt (23^2 - 4*1*23) / 2 * 1

x = sqrt (0 - -92) / 2

x = sqrt (92) / 2

x1 = 4.7958

x2 = -4.7958

What is the rate on an investment that doubles $5051 in 9 years? Assume interest is compounded quarterly.

Inessa [10]

Answer:

The rate at which the investment gets double is 7.776

Step-by-step explanation:

Given as :

The principal investment = $ 5051

The time period of investment = 9 years

Let The rate of interest = R % compounded quarterly

The Amount gets double

So, <u>From Compounded method</u>

Amount = Principal × $(1+\dfrac{rate}{4\times 100})^{4\times Time}$

Or, 2 × P = P × ( 1 + $\dfrac{\textrm R}{400})^{\textrm 36}$

Or, 2 = ( 1 + $\dfrac{\textrm R}{400})^{\textrm 36}$

Or, $2^{\frac{1}{36}}$ = 1 + $\dfrac{\textrm R}{400}$

or, 1.01944 - 1 = $\dfrac{\textrm R}{400}$

or, 0.01944 = $\dfrac{\textrm R}{400}$

∴ R = 0.01944 × 400 = 7.776

Hence The rate at which the investment gets double is 7.776 Answer

15. Estimate the product of 110.4 x 10.2 by rounding to the nearest whole number.

Pavel [41]

Answer: A.1100

Step-by-step explanation:

Hi, to answer this question we have to round each number to the nearest whole number:

110.4 = 110 (.4 is less than 5)

10.2 = 10

The product is the result of the multiplication of both numbers:

110 x 10 = 1,100

So, the correct option is A.1100
