Answer:

A= 12.57 inches squared

Step-by-step explanation:

The formula for the area of a circle is A=πr2. Substitute 2 for r, square it, and multiply it by pi (3.14.) The answer is 12.57 inches squared.

Answer:

[tex]\boxed {\tt a\approx 12.57 \ in^2}[/tex]

Step-by-step explanation:

The area of a circle can be found using the following formula.

[tex]a= \pi r^2[/tex]

The radius of the circle is 2 inches.

[tex]r= 2 \ in[/tex]

Substitute the value into the formula.

[tex]a=\pi ( 2 \ in)^2[/tex]

Evaluate the exponent.

[tex]a= \pi(4 \ in^2)[/tex]

Multiply.

[tex]a=12.5663706 \ in^2[/tex]

Round to the nearest hundredth. The 6 in the thousandth place tells us to round the 6 to a 7.

[tex]a\approx12.57 \ in^2[/tex]

The area of the circle is about 12.57 square inches.

Answer:

The two numbers are negative 1 and negative 9 which is -1 and -9

5x² + 2x - 3 < 0

5x² + 2x < 3

x² + 2/5 x < 3/5

Complete the square on the left side:

x² + 2/5 x + 1/25 - 1/25 < 3/5

(x + 1/5)² - 1/25 < 3/5

(x + 1/5)² < 16/25

Take the square root of both sides, keeping in mind that √(x²) = |x| for all x.

√((x + 1/5)²) < √(16/25)

|x + 1/5| < 4/5

This means

-4/5 < x + 1/5 < 4/5

-1 < x < 3/5

Answer:

B. Reject the claim that the proportion of Americans that have seen a UFO is equal to 2 in a thousand when that proportion is actually 2 in a thousand

Step-by-step explanation:

The type I error is rejection of true null hypothesis.

In the given scenario our hypothesis are

Null hypothesis: The proportion of Americans that have seen a UFO is equal to 2 in a thousand.

Alternative hypothesis: The proportion of Americans that have seen a UFO is less than 2 in a thousand.

Type I error is the rejection of true null hypothesis so, in this case type I error is rejection of claim  that the proportion of Americans that have seen a UFO is equal to 2 in a thousand when that proportion is actually 2 in a thousand.

Answer:

26,676population

Step-by-step explanation:

Population in 2010 = 24,700

If it grows yearly by 1%, increment per year is expressed as:

1% of 24,700

= 1/100×24700

= 247 populations

After 8years, population increase will be 247×8 = 1976 population

Statesville population in 2018 will be expressed as;

Population in 2010+increase after 8years

= 24700+1976

= 26,676 population

Hence statesville population in 2018 will be 26,676population

An expression is defined as a set of numbers, variables, and mathematical operations. The solution for the expression  39 ÷ (2 + 1) - 2 × (4 + 1) is 3.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Using the rule of BODMAS the solution for the expression  39 ÷ (2 + 1) - 2 × (4 + 1) is,

39 ÷ (2 + 1) - 2 × (4 + 1)

=  39 ÷ (3) - 2 × (5)

= 13 - 2  × (5)

= 13 - 10

= 3

Hence, the solution for the expression  39 ÷ (2 + 1) - 2 × (4 + 1) is 3.

Step-by-step explanation:

All you have to do is add the sides that you know and triangles total is 180 so add 32+58 and u get 90 degrees then u will have to subtract 180 from 90 and it equals 90 which is your missing angle

Answer:

0.72

Step-by-step explanation:

Answer:

We can see that:

a₀ = 4

a₁ = 4/3

a₂ = 4/9.

We easily can see that the n-th therm of this will be:

aₙ = 4/3^n.

Now, the denominator increases as n increases, then for a really large n, aₙ will tend asymptotically to zero. This means that this summation converges.

We can write this summation as:

4*∑(1/3)^n.

The sum for the first N-th therms is:

We know that for a summation:

1 + r + r^2 + r^3 + ... + r^N = (1 - r^(N + 1))/(1 - r)

4 + 4*(1/3) + 4*(1/3)^2 + ... + 4*(1/3)^N = 4*( 1 - (1/3)^(N + 1))/(1 - (1/3))

Now, for the complete sum we have that:

n = {0, 1, 2, ...}

We know that for a summation:

∑a*r^n

with n = {0, 1, ...}

the sum is = a/(1 + r).

in this case we have:

a = 4, r = 1/3.

Then the sum is:

S = 4/(1 - 1/3) = 4/(2/3) = 3*2 = 6

Answer:

No, The answer is 20. Remember area of triangle equals 1/2bh (or half of base and height multiplied.)

The area of triangle that has a base length of 10 inches and a height of 4 inches is 20 square inches.

The area of a triangle is one half the product of its base multiplied by height. Mathematically -

Area [Δ] = 1/2 x base x height

Given is a triangle (Δ) has a base length of 10 inches and a height of 4 inches.

We can write -

Base Length [B] = 10 inches

Height of triangle [H] = 4 inches

Area of triangle (Δ) = 1/2 x B x H

A(Δ) = 1/2 x B x H

A(Δ) = 1/2 x 10 x 4

A(Δ) = 20 square inches

Therefore, the area of triangle that has a base length of 10 inches and a height of 4 inches is 20 square inches.
