Answer:

<h2>A</h2>

Step-by-step explanation:

la recta:

y-yo=m(x-xo) (*)

P=(xo,yo)

m=\frac{Ya-Yb}{Xa-Xb}

substituindo:

m=\frac{3-7}{1-3}\\\\m=2

Seja P=A=(xo=1,yo=3), utilizando a formula (*)

y-3=2(x-1)\\y=2x-2+3\\y=2x+1

Use the remainder theorem to divide 5x^2+9x-2 by x+3. what is the remainder?
Anna [14]

Answer:

A)16

Step-by-step explanation:

Given

f(x)=5x^2+9x-2

Remainder theorem states that when f(x) is divided by x-a then the remainder can be calculated by calculating f(a).

Now Using the remainder theorem to divide 5x^2+9x-2 by x+3 to find the remainder:

f(x)=5x^2+9x-2

f(-3) = 5(-3)^2 +9(-3) -2

       =5(9) - 27 -2

       = 45-29

       = 16 !

Can someone please help?
Eva8 [605]

Answer: OPTION C

Given the functions shown in the figure attached, you have that f(x)*g(x), means that you must multiply both functions.

Therefore, you have:

f(x)*g(x)=(12x^{2}-6x)(2x)

Now, you must apply the distributive property, therefore, you obtain:

f(x)*g(x)=24x^{3}-12x^{2}

As you can see, the answer is the Option C.

<h3>(20 - 15)/20 x 100 = (5/20) x 100 = 25% decrease</h3>

2 Original amount: 30

End amount: 45

<h3>(45 - 30)/30 x 100 = (15/30) x 100 = 50% increase </h3>

3 Original amount: 625

End amount: 550

<h3>550/625 =550 ÷ 625 =0.88</h3><h3>0.88 =0.88 × 100/100 =(0.88 × 100)/100 =88/100 =88% decrease</h3>

4 Original amount: 320

End amount: 112

<h3>(112-320):320x100 =</h3><h3>100 =(112:320-1)x100 =</h3><h3>100 =35-100 = -65% decrease</h3>

5 Original amount: 165

End amount: 222.75

<h3>165/222.75 =165 ÷ 222.75 ≈0.740740740740741</h3><h3>0.740740740740741 =0.740740740740741 × 100/100 =(0.740740740740741 × 100)/100 ≈74.074074074074/100 =74.074074074074% ≈74.07% Increase </h3>
