Answer:

$5 {x}^{2} + 2x = 7x + 3x \\ 5 {x}^{2} + 2x = 10x \\ 5 {x}^{2} = 10x - 2x \\ 5 {x}^{2} = 8x \\ 5x = 8 \\ x = \frac{8}{5} = 1.6 \\ thank \: you$

Solve for g. what is g equal to?

sweet [91]

Answer:

$\displaystyle g=\frac{4\pi^2l}{T^2}$

Step-by-step explanation:

Equation Solving

Given the equation

$\displaystyle l=\frac{gT^2}{4\pi^2}$

It's required to solve it for g. Let's swap sides of the equation:

$\displaystyle \frac{gT^2}{4\pi^2}=l$

Multiply by $4\pi^2$ to remove the denominator:

$\displaystyle gT^2=4\pi^2l$

Divide by $T^2$

$\boxed{\displaystyle g=\frac{4\pi^2l}{T^2}}$

Calculate the surface area of the closed half-cylinder. all measurements are in cm

AVprozaik [17]

Answer:

2656.31 $cm^{2}$

Step-by-step explanation:

To calculate the surface area, we need to find the area of all the faces, and add them together.

The faces of the cylinder are: the rectangular base, the curved top, and the two semicircles on the side.

Rectangular base:

A = length x width

A = 29.3 x 16.2

A = 474.66

Two semicircles:

A = $\pi$ x $radius^{2}$ (I'm using the formula for a circle, because the two semicircles are identical, so together they form a circle)

radius = 29.3/2 = 14.65

A = $\pi$ x $14.65^{2}$

A = 674.256 (rounded to 3 decimal places)

Curved top:

The curved top, when flattened out, becomes a rectangle with a length of 16.2. The width is equal to half the circumference of the circle formed by the two semicircles.

To find the width, use the circumference (C) formula.

C = $\pi$ x diameter

diameter = 29.3

C = $\pi$ x 29.3

C = 93.049 (rounded to 3 DP)

Area (of curved top) = length x width

A = 16.2 x 93.049

A = 1507.394 (rounded to 3 DP)

Surface Area

SA = 474.66 + 674.256 + 1507.394

SA = 2656.31 $cm^{2}$

Based on the information in the diagram, determine whether the figure is a parallelogram. If so, select the answer with the corr

krok68 [10]

Answer: D.yes, both pairs of opposite sides are congruent.

Step-by-step explanation:

A parallelogram is a kind of quadrilateral( a- closed polygon having four sides ) with opposite sides parallel and equal.

Its opposite angles are also congruent.

In the given figure , we have a quadrilateral.

Since , the opposite sides of the quadrilateral are shown equal.

Therefore , we can say that the given figure is a parallelogram.

Hence, the correct answer is D.yes, both pairs of opposite sides are congruent.
