Answer 1

Answer:

m<A = 69°

m<C = 69°

Step-by-step explanation:

From the question given above, the following data were obtained:

AB = AC

m<B = 42°

m<A =?

m<C =?

Since:

AB = AC

Therefore,

m<A = m<C

A + B + C = 180 (sum of angles in a triangle)

C + 42 + C = 180

Collect like terms

C + C = 180 – 42

2C = 138

Divide both side by 2

C = 138 / 2

C = 69°

Finally, we shall determine m<A. This can be obtained as follow:

m<A = m<C

m<C = 69°

Therefore,

m<A = 69°

(c) 3x31 x4 dxThis integral can be evaluated using the basic integration rules.This integral cannot be evaluated using the basic integration rule

Answers

Answer:

a) This integral can be evaluated using the basic integration rules. [tex]\int 11x^{4}dx = \frac{11}{5} x^{5}+C[/tex]

b) This integral can be evaluated using the basic integration rules. [tex]\int 8x^{1}x^{4}dx=\frac{4}{3}x^{6}+C[/tex]

c) This integral can be evaluated using the basic integration rules. [tex]\int 3x^{31}x^{4}dx=\frac{x^{36}}{12}+C[/tex]

Step-by-step explanation:

a) [tex]\int 11x^{4}dx[/tex]

In order to solve this problem, we can directly make use of the power rule of integration, which looks like this:

[tex]\int kx^{n}=k\frac{x^{n+1}}{n+1}+C[/tex]

so in this case we would get:

[tex]\int 11x^{4}dx=11 \frac{x^{4+1}}{4+1}+C[/tex]

[tex]\int 11x^{4}dx=11 \frac{x^{5}}{5}+C[/tex]

b) [tex]\int 8x^{1}x^{4}dx[/tex]

In order to solve this problem we just need to use some algebra to simplify it. By using power rules, we get that:

[tex]\int 8x^{1}x^{4}dx=\int 8x^{1+4}dx=\int 8x^{5}dx[/tex]

So we can now use the power rule of integration:

[tex]\int 8x^{5}dx=\frac{8}{5+1}x^{5+1}+C[/tex]

[tex]\int 8x^{5}dx=\frac{8}{6}x^{6}+C[/tex]

[tex]\int 8x^{5}dx=\frac{4}{3}x^{6}+C[/tex]

c) The same applies to this problem:

[tex]\int 3x^{31}x^{4}dx=\int 3x^{31+4}dx=\int 3x^{35}dx[/tex]

and now we can use the power rule of integration:

[tex]\int 3x^{35}dx=\frac{3x^{35+1}}{35+1}+C[/tex]

[tex]\int 3x^{35}dx=\frac{3x^{36}}{36}+C[/tex]

[tex]\int 3x^{35}dx=\frac{x^{36}}{12}+C[/tex]

Answer:

You would either need to complete the square, use the quadratic equation, or another method because when reduced by the common factor, the constant term c is prime which means that it is only divisible by one and itself. Because the possible rational factors determined by c do not add up to the b term, it cannot be factored.

Explanation:

3x² + 24x - 15 = 0

3(x² + 8x - 5) = 0

[find the greatest common factor between each term and move the coefficient outside of the expression; in this case it's 3 since 3 fits into numbers 3, 24, and -15 so that it cannot be reduced further]

Then you can either use the box or pq method (since a is 1) to find working factors.

x² + bx + c → (x + p)(x + q).

p + q = b.

pq = c.

In this case with 3(x² + 8x - 5), b is 8 and c is -5.

This means we need two numbers that add up to 8 and multiply to -5.

Since -5 is prime, our only options are ±1 for p and ∓5 for q. This is because these are the only factors which multiply to -5.

1 + -5 = -4 ≠ 8

-1 + 5 = 4 ≠ 8.

Since we cannot find rational solutions, this cannot be factored, and so we must use another method.

Answers

Given:

In circle P, m∠ADB is 25°.

To find:

The m∠APB.

Solution:

Central angle theorem: According to this theorem, the central angle of an arc is twice of inscribed angle of the same arc.

From the given figure it is clear that the ∠APB is the central angle and ∠ADB is the inscribed angle on the arc AB.

By using the central angle theorem, we get

[tex]m\angle APB=2\times m\angle ADB[/tex]

[tex]m\angle APB=2\times (25^\circ)[/tex]

[tex]m\angle APB=50^\circ[/tex]

Therefore, the correct option is D.

A' = (4, 4)

B' = (12, 4)

C' = (4, 10)

Step-by-step explanation:

Ok so you are given that the scale factor is 2. You will multiply 2 with the values given of point A, B, and C in order to find the value of point A', B', and C'.

A = (2, 2) ---> 2 × 2 = 4 and 2 × 2 = 4

A' = (4, 4)

B = (6, 2) ---> 6 × 2 = 12 and 2 × 2 = 4

B' = (12, 4)

C = (2, 5) ---> 2 × 2 = 4 and 5 × 2 = 10

C' = (4, 10)
