What is the area of the triangle?
Answers
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.
What is area of a triangle?
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.

find a formula for the nth partial sum of each series 4+(4/3)+(4/9) and use it to find the series’ sum of the series converges.
Answers
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

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.
What is an Expression?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.

show that 5x²+2x-3

the inequality
5x²+2x-3< 0
Answers
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

g Statesville population in 2010 was about 24,700, and was growing by about 1% each year. If this continues, what will Statesville population be in 2018? [Round to the nearest person.]
Answers
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

The radius of a circle is 2 inches. What is the circle's area?
Answers
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.
(2 in)²= 2 in * 2 in = 4 in²[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.

D. Fail to 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 greater than 2 in a thousand.
Answers
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.
