Answer:

aₙ = a₁ + (n-1).d

103

107

Step-by-step explanation:

This is an arithmetic sequence because the difference (d) between 2 successive numbers is constant.

d = 91 - 87 = 95 - 91 = 99 - 95 = 4

If the first term is a₁, we can find the n term using the following expression.

aₙ = a₁ + (n-1).d

Here, we want to find the fifth and sixth elements.

a₅ = 87 + (5-1).4 = 103

a₆ = 87 + (6-1).4 = 107

jada goes to get her hair done the cost for a haircut and blowout is 65.42 she leaves a 25% tip for the stylist what is the tota
Art [367]

Answer:

The total cost is $81.78

Step-by-step explanation:

First lets calculate the tip

tip = cost * percent of tip

tip = 65.42*.25

tip = 16.355

Which rounds to 16.36  since we are working with money and round to the nearest cent

total cost = cost of cut and blowout + tip

                = 65.42 +16.36

                     =81.78

Rewrite each fraction in simplest form using the GCF of the numerator and denominator.
Elanso [62]

Answer:

\sf 6. \quad \dfrac{7}{10}

\sf 7. \quad \dfrac{5}{17}

Step-by-step explanation:

<h3><u>Question 6</u></h3>

To find the greatest common factor (GCF), first list the prime factors of each number:

  • 42 = 2 × 3 × 7
  • 60 = 2 × 2 × 3 × 5

42 and 60 share one 2 and one 3 in common.

Multiply them together to get the GCF:  2 × 3 = 6.

Therefore, 6 is the GCF of 42 and 60.

Divide the numerator and the denominator by the found GCF:

\implies \sf \dfrac{42 \div 6}{60 \div 6}=\dfrac{7}{10}

<h3><u>Question 7</u></h3>

To find the greatest common factor (GCF), first list the prime factors of each number:

  • 80 = 2 × 2 × 2 × 2 × 5
  • 272 = 2 × 2 × 2 × 2 × 17

80 and 272 share four 2s in common.

Multiply them together to get the GCF:  2 × 2 × 2 × 2 = 16.

Therefore, 16 is the GCF of 80 and 272.

Divide the numerator and the denominator by the found GCF:

\implies \sf \dfrac{80 \div 16}{272 \div 16}=\dfrac{5}{17}

Help because I DONT know how to even start
Ierofanga [76]

Slope is rise/run or y2-y1/x2-x1. So to find the slope, find two points where the point is exact, then do the equation. That's the best I can explain, sorry if this doesn't help at all.

Given the graph of y=f(x), shown as a red dashed curve, drag the movable blue point to obtain the graph of y=f(x−4)+3.
Sergeeva-Olga [200]

Answer:

See graph in attachment.

Step-by-step explanation:

The graph of y=f(x) is a parabola that has its vertex at the origin.

The equation of the transformed graph is

y=f(x-4)+3

The vertex of this transformed function is

(4,3)

Drag the blue graph up so that the vertex will now be at (4,3).
