Answer:

= 121

Step-by-step explanation:

it's algebra questions. in Algebra there are some formula are necessary to remember.

(4+7)²+2³

> (4²+2×4×7+7²)+2×2×2×2

> (4×4+2×4×7+7×7)+16

> 8 +56+49+16

> 129

• Equation (4+7)²+2³ is equal to 129.

Help! Need answer right now!!

enyata [817]

Step-by-step explanation:

a = 1, b = 9, c = 8

with the quadratic formula;

x = -9 + \|9² - 4(1 × 8) ÷ 2(1) or x = -9 - \|9² - 4(1 × 8) ÷ 2(1)

x = -9 + \| 81 - 32 ÷ 2 or x = -9 - \| 81 - 32 ÷ 2

x = -9 + \| 49 ÷ 2 or x = -9 - \| 49 ÷ 2

x = -9 + 7 ÷ 2 or x = -9 - 7 ÷ 2

x = -2 ÷ 2 or x = -16 ÷ 2

x = -1 or x = -8

Derive the equation of the parabola with a focus at (0, −4) and a directrix of y = 4.

Goshia [24]

$\sqrt{(x_{0} - 0)^{2} + (y_{0} - (-4))^{2}} = |y_{0} - 4|$
<span> $\sqrt{(x_{0} - 0)^{2} + (y_{0} + 4)^{2}} = |y_{0} - 4|$
</span> $(x_{0} - 0)^{2} + (y_{0} + 4)^{2} = (y_{0} - 4)^{2}$
$(x_{0})^{2} + (y_{0} + 4)^{2} = (y_{0} - 4)^{2}$
$x_{0}^{2} + (y_{0}^{2} + 4y_{0} + 4y_{0} + 16) = y_{0}^{2} - 4y_{0} - 4y_{0} + 16$
$x_{0}^{2} + (y_{0}^{2} + 8y_{0} + 16) = y_{0}^{2} - 8y_{0} + 16$
$x_{0}^{2} + y_{0}^{2} + 8y_{0} + 16 = y_{0}^{2} - 8y_{0} + 16$
$x_{0}^{2} + 16y_{0} = 0$
$16y_{0} = -x_{0}^{2}$
$\frac{16y_{0}}{16} = \frac{-x_{0}^{2}}{16}$
$y_{0} = -\frac{1}{16}x_{0}^{2}$
$y = -\frac{1}{16}x^{2}$

Answer: 9.22

Step-by-step explanation:

2^2 + 9^2 = C^2

4+81=C^2

85=C^2

(square root both sides)

C=9.219544

C=9.22
