What is the product of 2.5 x 10^2 and 3.7 x 10^5 expressed in scientific notation?

Sergio039 [100]

Answer:

Step-by-step explanation:

2.5 x $10^{2}$ * 3.7 x $10^{5}$

add the expoents, and multiply the coefficients

2.5 * 3.7 =9.25

$10^{2+5}$ = $10^{7}$

9.25 x $10^{7}$

If (10,3) and (6,31) are two anchor points on a trend like, then find the equation of the line

Misha Larkins [42]

Answer:

let's find the gradient first. (m)

Step-by-step explanation:

(10,3) (6,31)

y²-y¹/x²-x¹

31-3/6-3

28/3

(m) =28/3

y-y¹=m(x-x¹)

let's take y¹=3, x¹=10 and m= 28/3

y-3=28/3(x -10)

y-3=(28/3)x -128/3

taking LCM=3

3y-9=28x-128

3y=28x -128+9

3y=28x-119

Soo your equation is:

3y=28x-119

What is Y=-2/-3x+4 simplified

marshall27 [118]

Answer:

y=2/3+4

Step-by-step explanation:

This equation is in Slope-Intercept form, the most common, therefore, y=-2/-3+4 just needs to apply the - x - = + rule to get, y=2/3+4

Find an equation of the plane that contains (3, 4, −9) and is parallel to x + y − 5z = 1. (Use x, y, and z for coordinates.)

emmainna [20.7K]

Answer:

x + y - 5z = 52

Step-by-step explanation:

Given data:

Point on the plane (3,4,-9)

parallel to x + y -5z = 1

Finding the normal vector

(1 , 1 , -5)(x, y , z) = 1

the normal vector is (1 , 1 , -5)

<em>formula for finding equation the plane given the normal vector (a,b,c) and point (m,n,o) is as </em>

Substituting the data we have

1(x-3) + 1( y- 4) - 5(z+9) =0

x-3 +y -4 -5z -45 = 0

x + y - 5z = 45 +4 +3

x + y - 5z = 52

Which is an equation in point slope form of the line that passes through the points (7 -8) and has a slope of -3

Nataly [62]

Y+8 = -3(x-7)
Distribute the -3
y +8 = -3x +21
Subtract 8 from both sides
Y = -3x +21 -8
Y= -3x+13
