Answer:

y=a(x+4)^2 +1, for a real number a hat is different of 0.

Step-by-step explanation:

If we know only the vertex, there are many quandratic equations.

* Result: Vertex (m,n), the quadratic equation is y= a(x-m)^2 + n for a real number a that is different of 0.

Here, the vertex (-4,1), we have the equation: y=a(x+4)^2 +1, for a real number a hat is different of 0.

Hope you understand.

Evaluate the dot product of (7, 5) and (- 5, 4)
melamori03 [73]

Answer:

The dot product of (7,5) and (-5,4) is -15

Step-by-step explanation:

Given

(7,5) and (-5,4)

Required

Determine the dot product

Dot product is calculated using the following formula;

a.b = {a_1b_1+a_2b_2+...+a_nb_n}

Let a = (7,5) and b = (-5,4);

The above formula becomes

a.b = {7*-5+5*4}

a.b = {-35+20}

a.b = {-15}

Hence, the dot product of (7,5) and (-5,4) is -15

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

(9x + 17) +2 \times  ( 5x + 15 ) + (6x - 12) = 360 \\

9x + 17 + 10x + 30 + 6x - 12 = 360 \\

9x + 10x + 6x + 17 + 30 - 12 = 360 \\

Collect like terms

25x + 35 = 360

Subtract sides 35

25x + 35 - 35 = 360 - 35

25x = 325

Divide sides by 25

\frac{25x}{25}  =  \frac{325}{25}  \\

x = 13

Thus ;

RQ  \:  \: arc =2 \times (5x + 15)

RQ  \:  \: arc = 10x + 30

RQ  \:  \: arc = 10(13) + 30

RQ  \:  \: arc = 130 + 30

RQ \:  \:  arc = 160°
