Find the GCF of the following monomials. -50m 4 n 7 and 40m 2 n 10

Answers

Answer 1

Answer:

Answer:

$10m^2n^7$

Step-by-step explanation:

$-50m^4n^7 \ and \ 40m^2n^(10)$

WE need to find GCf for both monomials. GCF is the greatest common factor

$-50 ->-1 \cdot 5 \cdot 5 \cdot 2$

$40 ->2 \cdot 2 \cdot 5 \cdot 2$

GCF is 2 times 5 =10

GCF of exponent is the lowest exponent

GCF of m^4 and m^2 is m^2

GCF of n^7 and n^10 is n^7

$-50m^4n^7 \ and \ 40m^2n^(10)$

GCF is $10m^2n^7$

Mike recently increased the size of his Jeep tires from the original 29 inch diameter to the larger 33.73 inch diameter. If Mike didn't recalibrate his speedometer, how fast is he really going on the new tires when his speedometer shows he is traveling 60 mph?a. 54.5 mph
b. 62.1 mph
c. 66.1 mph
d. 69.8 mph

Answers

Answer:

d. 69.8 mph

Step-by-step explanation:

Since, the ratio of the diameter of the tyre of a vehicle and its speed must be constant,

Given,

The original diameter of the tyre = 29 inch,

Original speed = 60 mph,

Thus, the ratio of diameter and the speed of the vehicle = $(29)/(60)$

New diameter of the tyre = 33.73 inch,

Let x be the new speed of the vehicle = $(33.73)/(x)$

$\implies (29)/(60)=(33.73)/(x)$

$\implies x=(33.73* 60)/(29)=69.79\approx 69.8\text{ mph}$

Hence, the actual speed of the vehicle would be 69.8 mph.

OPTION D is correct.

2x+y=4
Y=2/3x-4

Answers

so you subsitute y=2/3x-4 for y in 2x+y=4 so
2x+(2/3x-4)=4
2x+2/3x-4=4
add like terms
2 and 2/3x-4=4
add 4 to both sidees
2 and 2/3x=8
2 and 2/3=6/3+2/3=8/3
8/3x=8
multiply both sides by 3/8 (makes 8/3=24/24=1/1=1)
x=(3*8)/8
simplify
x=3
subtitute x=3 into y=2/3x-4
y=2/3(3)-4
y=(6/3)-4
y=2-4
y=-2

Which of the following functions has the greatest y-intercept?f(x)

x y
−3 −15
−2 −8
−1 −1
0 3
1 6
2 10
g(x) = −4 sin(5x) + 3

Answers

The y intercept occurs when x = 0

So for first function y-intercept = 3.

Second function:-

y intercept = -4 sin (5*0) + 3

= -4(0) + 3 = 3

y - intercepts are equal.
