Find the are of a triangle (picture provided)

Answers

Answer:

Step-by-step explanation:

Use the Heron's formula for the area of the triangle:

$A=√(p(p-a)(p-b)(p-c)),$

where a, b, c are lengths of triangle's sides and $p=(a+b+c)/(2).$

Since $a=11.5,\ b=13.7,\ c=12.2,$ then

$p=(11.5+13.7+12.2)/(2)=18.7.$

Hence,

$A=√(18.7(18.7-11.5)(18.7-13.7)(18.7-12.2))=√(18.7\cdot 7.2\cdot 5\cdot 6.5)=\n \n=√(11\cdot 1.7\cdot 9\cdot 4\cdot 0.2\cdot 5\cdot 5\cdot 1.3)=30√(11\cdot 1.7\cdot 0.2\cdot 1.3)=30√(4.862)\approx 66.1\ un^2.$

Answer:

Choice b is correct.

Step-by-step explanation:

We have given the sides of triangle.

a = 11.5, b = 13.7 and c = 12.2

We have to find the area of the triangle.

The formula to find the area of the triangle when three sides are given is:

A = √p(p-a)(p-b)(p-c)

where p = (a+b+c) / 2

p = (11.5+13.5+12.2)/2

p = 18.7

A = √18.7(18.7-11.5)(18.7-13,7)(18.5-12.2)

A = 30√4.862 units²

A≈ 66.1 units²

What is the factored form of the polynomial? x2 - 15x + 36

Answers

Answer:

$(x-12)(x-3)$

Step-by-step explanation:

We have been given an polynomial $x^2-15x+36$ and we are asked to factor our given polynomial.

We will factor our given polynomial by splitting the middle term in two numbers such that the numbers add up-to -15 and their product will be equal to 36.

We know that -12 and -3 add up-to -15 and their product is 36. So splitting the middle term of our given polynomial we will get,

$x^2-12x-3x+36$

$x(x-12)-3(x-12)$

$(x-12)(x-3)$

Therefore, the factored form of our given polynomial is $(x-12)(x-3)$ .

The factored form of the polynomial $x^2 - 15x + 36$ is $(x - 3)(x - 12)$ .

To find the factored form of the polynomial $x^2 - 15x + 36$ , we can look for two binomials that, when multiplied, give us the original polynomial.

The general form of a quadratic polynomial in factored form is $(x - r_1)(x - r_2).$

where $r_1$ and $r_2$ are the roots of the polynomial.

Now, find two numbers whose product is 36 and whose sum is -15.

The numbers that satisfy these conditions are -3 and -12,

since $(-3) * (-12) = 36$ and

$(-3) + (-12) = -15.$

Therefore, we can factor the polynomial as:

$x^2 - 15x + 36$

$x^2 - 12x-3x+36$

$x(x-12)-3(x-12)$

$= (x - 3)(x - 12)$

So, the factored form of the polynomial $x^2 - 15x + 36$ is $(x - 3)(x - 12)$ .

Isolate c
a=b(1/c-1/d)

Answers

A= b(1/c - 1/d)
A/b = 1/c -1/d
A/b + 1/d = 1/c
(A/b + 1/d) 1 = c

Answer: c = b/(a + 1).

Step-by-step explanation:

a = b(1/c - 1/d)

Expand RHS by first finding LCM

a = b((d — c)/cd)

a = (bd — bc)/cd

Then cross multiply

acd = bd — cd

Collect the terms having c to the LHS

acd + cd = bd

Factorise cd out of LHS

( a+ 1)dc = bd

c = bd/(a + 1)d

c = b/(a + 1).

Final answer:

The solution to the given inequality, |2x + 1| ≤ 3, is the set { -2 ≤ x ≤ 1 }, which corresponds to answer choice (c). This is achieved by solving two separate inequalities, 2x + 1 ≤ 3 and - (2x + 1) ≤ 3.

Explanation:

The subject of the question is Mathematics, specifically a High School algebra topic on solving absolute inequalities. The student's question is asking us to solve the inequality |2x + 1| ≤ 3. To do this, we need to create and solve two separate inequalities: 2x + 1 ≤ 3 and - (2x + 1) ≤ 3.

Solving 2x + 1 ≤ 3 gives us 2x ≤ 2 and x ≤ 1 . Solving - (2x + 1) ≤ 3 gives us -2x - 1 ≤ 3 , then -2x ≤ 4 , and finally x ≥ -2 . Combining these answers gives us the solution set { -2 ≤ x ≤ 1 }, which corresponds to answer choice (c).
