5,25,125 find 10th term
anastassius [24]

Answer:

9765625

Step-by-step explanation:

There is a common ratio between consecutive terms , that is

r = 25 ÷ 5 = 125 ÷ 25 = 5

This indicates the sequence is geometric with n th term

a_{n} = a₁r^{n-1}

where a₁ is the first term and r the common ratio

Here a₁ = 5 and r = 5 , then

a₁₀ = 5 × 5^{9} = 5 × 1953125 = 9765625

Which is the vertex of x2 + 10x = -17 <br><br> (-5,-8)<br><br> (5,8)<br><br> (-5,8)<br><br> (5,-8)
ad-work [718]

Answer:

vertex = (- 5, - 8)

Step-by-step explanation:

Given a quadratic in standard form : ax² + bx + c = 0 : a ≠ 0

Then the x- coordinate of the vertex is

x_{vertex} = - \frac{b}{2a}

Given x² + 10x = - 17 ( add 17 to both sides )

x² + 10x + 17 = 0 ← in standard form

with a = 1, b = 10, c = 17, then

x_{vertex} = - \frac{10}{2} = - 5

Substitute x = - 5 into the quadratic for the corresponding value of y

y = (- 5)² + 10(- 5) + 17 = 25 - 50 + 17 = - 8

Hence vertex = (- 5, - 8)

The graphed line can be expressed by which equation?
earnstyle [38]

Answer:

The Answer is: y = 2/3x - 2/3

Step-by-step explanation:

Given points: (4, 2) and (-2, -2)

Find the slope m:

m = y - y1 / (x - x1)

m = 2 - (-2) / (4 - (-2))

m = 2 + 2 / (4 + 2)

m = 4 / 6 = 2/3

Use the point slope form, substitute the point (4, 2) and solve for y to get the point slope form:

y - y1 = m(x - x1)

y - 2 = 2/3(x - 4)

y - 2 = 2/3x - 8/3

y = 2/3x - 8/3 + 6/3

y = 2/3x - 2/3

Proof:

f(-2) = 2/3(-2) - 2/3

= -4/3 - 2/3 = -6/3 = -2, giving (-2, -2)

Hope this helps!! Have an Awesome Day!! :-)
