mel-nik [20]2 years ago
4 0

Answer:

5, 9

Step-by-step explanation:

To obtain the next term in a sequence add the common difference d to the previous term.

d = a₂ - a₁ = - 3 - (- 7) = - 3 + 7 = 4

Thus

a₄ = a₃ + 4 = 1 + 4 = 5

a₅ = a₄ + 4 = 5 + 4 = 9

Write the equation of the circle with center (7,-2) and radius square root 61. Please show your work!
Vladimir79 [104]
The equation of a circle is (x - h)^2 + (y - k)^2 = r^2
x and y are left alone in a circle equation, while h and k are the coordinates of the center.

Thus, our equation is (x - 7)^2 + (y + 2)^2 = 61

kifflom [539]

Answer:

792\ \text{pounds}

Step-by-step explanation:

x_1=70 cubic feet of fertilizer is used in y_1=770 pounds of strawberries

x_2=90 cubic feet of fertilizer is used in y_2=990 pounds of strawberries

x=72 cubic feet of fertilizer is used

Linear interpolation is applied

y=y_1+\dfrac{(x-x_1)(y_2-y_1)}{x_2-x_1}\\\Rightarrow y=770+\dfrac{(72-70)(990-770)}{90-70}\\\Rightarrow y=792\ \text{pounds}

72 cubic feet of fertilizer will yield 792\ \text{pounds} of strawberries.

The length of a rectangle is 2 units shorter than one-fifth of the width, x.
sergey [27]

Answer:

C. P=\frac{12x}{5} + 4

Step-by-step explanation:

Width = x

Length = one fifth of width minus 2

Length = \frac{1}{5}x-2

Perimeter is given by the formula

P=2(l+b)

P=2(\frac{1}{5}x-2+x)

P=2(\frac{x}{5}-2+x)

P=2\times \frac{x-2 \times 5+5 \times x}{5}

P=2\times \frac{x-10+5x}{5}

P=2\times \frac{6x}{5} - 2\times \frac{-10}{5}

P=2\times \frac{6x}{5} + 2\times \frac{10}{5}

P=\frac{12x}{5} + 4
