7. 

One way to figure this out is to go from 2-10, and multiply them by them self each other to see what number works. 

Another way is to use a calculator and the square root button. 

Hope that helps!

Please help I have no idea how to answer this question
mr_godi [17]

Answer:

n = 3

Step-by-step explanation:

plug in 3 for n in the equation:

Numerator: n + 1 = 3 + 1 = 4

Denominator: 2^n = 2^3 = 2 * 2 * 2 = 4 * 2 = 8

Simplify the fraction. Divide common factors from both the numerator and denominator:

(4/8)/(4/4) = 1/2

1/2 = 1/2 ∴ n = 3

Twice the sum of a number and 9 equals 6
Korvikt [17]
Let's make the equation.
2(N+9)=6
Let's divide both sides by 2.
n+9=3
Now subtract 9 from both sides.
n=-6
So, the number is -6.

Use finite approximation to estimate the area under the graph of f(x) = 5^2 and above the graph of f(x) = 0 from X(o) = 0 to x(n
In-s [12.5K]

Finite approximation method of estimating the area under the curve of the

given function makes use of rectangular approximation of the area.

The correct responses are;

i) The estimated area using a lower sum with two rectangles of equal width is <u>1,715 square units</u>.

ii) The estimated area using a lower sum with four rectangles of equal width is <u>3,001.25 square units</u>.

iii) The estimated area using an upper sum with two rectangles of equal width is<u> 8,575 square units</u>.

iv) The estimated area using a upper sum with four rectangles of equal width is <u>6,431.25 square units</u>.

Reasons:

The given function is f(x) = 5·x²

The given domain is x₀ to x₁₄

i) Estimate using lower sum with two rectangles of equal width;

Let \ \Delta x = \dfrac{14}{2} = 7 \ we \ get;

f(0) = 0

f(7) = 5 × 7² = 245

A = 0 × 7 + 245 × 7 = 1,715

The estimated area using a lower sum with two rectangles of equal width

is <u>1,715 square units</u>.

ii) Estimate using lower sum with four rectangles of equal width;

Let \ \Delta x = \dfrac{14}{4} = 3.5 \ we \ get;

f(0) = 0

f(3.5) = 5 × 3.5² = 61.25

f(7) = 5 × 7² = 245

f(10.5) = 5 × 10.5² = 551.25

A = 0 × 3.5 + 61.25 × 3.5 + 245 × 3.5 + 551.25 × 3.5 = 3,001.25

The estimated area using a lower sum with four rectangles of equal width is <u>3,001.25 square units</u>.

iii) Estimate using an upper sum with two rectangles of equal width;

Let \ \Delta x = \dfrac{14}{2} = 7 \ we \ get;

f(7) = 5 × 7² = 245

f(14) = 5 × 14² = 980

A = 245 × 7 + 980 × 7 = 8575

The estimated area using an upper sum with two rectangles of equal width

is <u>8,575 square units</u>.

iv) Estimate using an upper sum with four rectangles of equal width;

Let \ \Delta x = \dfrac{14}{4} = 3.5 \ we \ get;

f(3.5) = 5 × 3.5² = 61.25

f(7) = 5 × 7² = 245

f(10.5) = 5 × 10.5² = 551.25

f(14) = 5 × 14² = 980

A = 61.25 × 3.5 + 245 × 3.5 + 551.25 × 3.5 + 980 × 3.5 = 6,431.25

The estimated area using a upper sum with four rectangles of equal width

is <u>6,431.25 square units</u>.
