what is the rule for the reflection ?
a. rx-axis(x, y) - (-x, y)
b. ry-axis(x, y) - (-x, y)
c. rx-axis(x, y) - (x,-y)
d. ry-axis(x, y) - (x,-y)

What Is The Rule For The Reflection ?a. Rx-axis(x, Y) - (-x, Y)b. Ry-axis(x, Y) - (-x, Y)c. Rx-axis(x,

Answers

Answer 1

Answer: Choice C

We have an x axis reflection

[tex](x,y) \to (x,-y)[/tex]

The x coordinate stays the same while the y coordinate flips from positive to negative, or vice versa.

For example, point L is located at (-4,2) and it moves to L ' (-4, -2). The other points follow this same pattern.

X^2 +6x+30 in vertex form

Answers

Answer:

Step-by-step explanation:

Factoring  x2-6x-30

The first term is,  x2  its coefficient is  1 .

The middle term is,  -6x  its coefficient is  -6 .

The last term, "the constant", is  -30

Step-1 : Multiply the coefficient of the first term by the constant   1 • -30 = -30

Step-2 : Find two factors of  -30  whose sum equals the coefficient of the middle term, which is   -6 .

     -30    +    1    =    -29

     -15    +    2    =    -13

     -10    +    3    =    -7

     -6    +    5    =    -1

     -5    +    6    =    1

     -3    +    10    =    7

     -2    +    15    =    13

     -1    +    30    =    29

The correct answer is 29 vertex

Find the coeficcient of the x4y3 term in the expansion of (2x+y)7

Answers

By the binomial theorem,

[tex]\displaystyle (2x+y)^7 = \sum_{k=0}^7 \binom7k (2x)^{7-k} y^k=\sum_{k=0}^7 \binom7k 2^{7-k} x^{7-k} y^k[/tex]

where

[tex]\dbinom nk=\dfrac{n!}{k!(n-k)!}[/tex]

is the binomial coefficient.

We get the x⁴y³ terms with k = 3, for which the coefficient would be

[tex]\dbinom73 2^{7-3}=\dfrac{7!}{3! 4!} 2^4=\boxed{560}[/tex]

In triangle ABC, the measure of angle B is 50 degrees. Select all possible values for the measures of A and C if ABC is an acute triangle. m\angle∠A= 58 degrees; m\angle∠C= 72 degrees m\angle∠A= 100 degrees; m\angle∠C= 30 degrees m\angle∠A= 80 degrees; m\angle∠C= 50 degrees m\angle∠A= 60 degrees; m\angle∠C= 70 degrees m\angle∠A= 90 degrees; m\angle∠C= 40 degrees m\angle∠A= 105 degrees; m\angle∠C= 25 degrees

Answers

Answer:

Step-by-step explanation:

Sum of angle in a triangle = 180°

<A+<B+<C = 180

Given <B = 50°

Substituting into the formula

<A+50+<C = 180

<A+<C = 180-50

<A+<C = 130°

Since the ∆ABC is an acute triangle, the angles <A and <C must be angles less than 90° since acute angles are angles less than 90°

The possible values of <A and <C that will be acute and give a sum of 130° are;

∠A= 58° and ∠C= 72°

∠A= 80° and ∠C= 50°

∠A= 60° and ∠C= 70°

You can see that all the Angles are less than 90° and their sum is 130°
