Janice is asked to solve0=64x^2+16x-3 what is x

Mathematics
1 answer:
Papessa [141]3 years ago
8 0

Answer:

x=-1/8 or 3/8

Step-by-step explanation:

64x^2+16x-3=0

By Mid term breaking

64x^2-24x+8x-3=0

8x(8x-3)+1(8x-3)=0

(8x+1)(8x-3)=0

Either

8x+1=0 OR 8x-3=0

8x=-1 OR 8x=3

x=-1/8 OR x=3/8

Choose the correct equation for the line shown on the graph?

<u>Answer:</u>

y=-1/4x-1

<u>How to find the </u><u>slope</u>

To find the slope of the line you need to do the change in y/change in x. This is also known as the rise/run. To do this you count the spaces in between the two points.

In this graph the change in y (rise) is 2. The change in x (run) is 8. Since the line is going down they are negative. The rise/run is -2/8. This can be simplified to -1/4.

Slope: -1/4x

<u>How to find the y-intercept</u>

To find the y-intercept, you need to look at where the line crosses y.

In this graph the line crosses y at -1.

Y-intercept: -1

How long is the arc intersected by a central angle of StartFraction 5 pi Over 3 EndFraction radians in a circle with a radius of
qaws [65]

The length of the arc of the circle with a radius of 2 ft and the angle made at the centre equal to \dfrac{5\pi}{3} is 10.5ft.

<h3>What is the length of the arc of a circle?</h3>

The length of the arc of a circle is equal to the product of the circumference of the circle and the ratio of the angle made by the arc of the circle to 2π. It is given by the formula,

\text{Length of the arc}= 2\pi r\times \dfrac{\theta}{2\pi}

It is given that the radius of the circle is equal to 2 ft while the angle made by the arc at the centre of the circle is equal to \dfrac{5\pi}{3}. And we know the formula for the length of the arc, therefore, the length of the arc,

\text{Length of the arc}= 2\pi r\times \dfrac{\theta}{2\pi}

                            = 2\pi \times 2 \times \dfrac{\frac{5\pi}{3}}{2\pi}\\\\= 10.471 \approx 10.5\rm\  ft

Hence, the length of the arc of the circle with a radius of 2 ft and the angle made at the centre equal to \dfrac{5\pi}{3} is 10.5ft.
