Answer:

y= -1/2x + 2

or y = -0.5x + 2

Step-by-step explanation:

Use the slope formula to get the slope:

(y2-y1)/ (x2-x1)

(2-0)/(0-4)

2/-4

-1/2

Plug in any point in Point-Slope Formula:

y - y1 = m(x-x1)

y- 0 = -1/2 (x -4)

y = -x/2 + 4/2

y= -1/2x + 2

Answer:

Step-by-step explanation:

you have a right triangle

to find the missing length(x) you will use

a^2+b^2=c^2

where c is the hypotenuse

49^2=25^2+x

x^2=49^2-25^2=2401-625=1776

x= $\sqrt{1776}$ =42.1

The diameter of a circleis 170inches. The circle has two chords of length 26 inches. What is the distance from each chord to the

vivado [14]

Answer:

Hence the Distance from each other chord to center is 84 inches.

Step-by-step explanation:

Given:

Diameter =170 inches

2 chords with each length =26 inches.

To Find:

Distance of each chord from the circle.

Solution:

Consider a circle with center as O ,

And OA as Radius

(Refer the attachment)

So as chord be BC and DE respectively with each of 26 length

They have both same length so they should located at same distance from center but as mirror images of each other opposite side of the diameter as shown in fig.

Hence we can calculate for one chord as follows:

Radius =diameter/2=170/2=85

r=85 inches.

Let distance from center t o chord be 'x'

Now draw perpendicular to chord BC with F as midpoint for chord and join endpoints of chord to the center which forms triangle OFC as right angled triangle,

By using pythagorus Theorem

$OC^2=FC^2+OF^2$

Here OC=85 inches , FC=26/2=13 inches.

$85^2=13^2+OF^2$

$OF^2=85^2 -13^2$

$OF^2=7225-169$

$OF^2=$ 7056

$OF=84$ inches

Hence the Distance from each other chord to center is 84 inches.

I need not just the answer but the work written out

Mekhanik [1.2K]

Answer:

A(3) = -6 + (3 - 1) (5)

-6 + (2)(5)

-6 + (10)

A(4) = -6 + (4 - 1) (5)

-6 + (3)(5)

-6 + 15

A(10) = -6 + (10 - 1) (5)

-6 + (9)(5)

-6 + 45

Identify like terms of 8a b2 b3 4b2 4 5a

ipn [44]

Like terms are any terms that have the same variable value.

In the sequence 8a, b^2, b^3, 4b^2, 4, and 5a, the like terms are the ones that have the same variable to the same power.

8a and 5a are like terms, as well as b^2 and 4b^2, because both sets of terms have the same variable.
Hope that helped =)
