If degree measures of the angles of A ABC are represented by 3x, x+10,

and 6x, then A ABC must be...

Answers

Answer:

30degrees

Step-by-step explanation:

The sum of angles of a triangle is 180

<A + <B + <C = 180

Substitute the given values

3x + x+10 + 6x = 180

10x + 10 = 180

10x = 180-10

10x = 170

x = 170/10

x = 17

Get <A:

<A = 3x

<A = 3(10)

<A = 30degrees

Hence the measure of angle A is 30degrees

Find the vertex of the parabola. y = negative 4 x squared + 24 x minus 35 a. ( -3, 1) c. ( 3, 1) b. ( -3, -1) d. ( -1, -3)

Answers

Answer:

(3, 1)

Step-by-step explanation:

y = -4x² + 24x - 35

Find the vertex by using the formula:

(h, k) → [tex]\displaystyle \Big [ -\frac{b}{2a}, \ f \Big (-\frac{b}{2a} \Big ) \Big ][/tex]

In this problem, we have:

a = -4 b = 24 c = -35

Using 24 for b and -4 for a, we can substitute these values into the vertex formula:

[tex]\displaystyle -\frac{b}{2a} \rightarrow -\frac{24}{2(-4)} = \frac{-24}{-8} = 3[/tex]

The h-value for the vertex is 3.

Now let's plug 3 back into the standard form equation to solve for the k-value of the vertex.

[tex]-4x^2 + 24x - 35 \rightarrow -4(3)^2+24(3)-35 = -36 + 72 - 35 = 1[/tex]

The k-value for the vertex is 1.

The vertex of the parabola is (3, 1).
