-3z + 7 = -7 - 10z

Add 10z to both sides

7z + 7 = -7

Subtract 7 from both sides

7z = -14

Divide by 7

Z = -2

-3z+7=-7-10z -3z+10z=-7-7 7z=-14 (divide both sides by 7) z=-2

The gravitational force exerted by the planet Earth on a unit mass at a distance r from the center of the planet is F(r) = GMr R

bagirrra123 [75]

Answer:

Yes the function is continuous.

Step-by-step explanation:

Given

$F(r)=\frac{GMr}{R^{3}}(r< R)$ and $F(r)=\frac{GM}{r^{2}}(r\geq R)$

For a function to be continuous we should have

$\lim_{r\rightarrow R^{-}}F(r)=\lim_{r\rightarrow R^{+}}F(r)$

Thus

$\lim_{r\rightarrow R^{-}}F(r)=\frac{GMR}{R^{3}}=\frac{GM}{R^{2}}$

Similarly we have

$\lim_{r\rightarrow R^{+}}F(r)=\frac{GM}{R^{2}}$

thus we can see that

$\lim_{r\rightarrow R^{-}}F(r)=\lim_{r\rightarrow R^{+}}F(r)$

Hence the function is continuous.

A wallet contains five $10 bills, three $5 bills, six $1 bills, and no larger denominations. If bills are randomly selected one-

Black_prince [1.1K]

Answer:

$\frac{4}{21}$

Step-by-step explanation:

Another way of phrasing this question is this; if only two bills are selected without replacement, what is the probability that at one of the two bills will be a $10 bill:

P(One $10 bill) = P(picking a $10 bill first then another type) + (picking another

type then a $10 bill)

= $\frac{5}{15}*\frac{10}{14}+\frac{10}{15} *\frac{5}{14} = \frac{4}{21}$

Which angle measures are correct? Select three options. mAngle2 = 125° mAngle3 = 55° mAngle8= 55° mAngle12 = 100° mAngle14 = 100

RUDIKE [14]

Answer:

m<2 = 125°, m<8 = 55° and m<14 = 100°

Step-by-step explanation:

The question is incomplete.

Lines e and f are parallel. The mAngle9 = 80° and mAngle5 = 55°. Parallel lines e and f are cut by transversal c and d. All angles are described clockwise, from uppercase left. Where lines e and c intersect, the angles are: 1, 2, 4, 3. Where lines f and c intersect, the angles are 5, 6, 8, 7. Where lines e and d intersect, the angles are 9, 10, 12, 11. Where lines f and d intersect, the angles are 13, 14, 16, 15. Which angle measures are correct? Select three options. mAngle2 = 125° mAngle3 = 55° mAngle8= 55° mAngle12 = 100° mAngle14 = 100

Given

m<9 = 80°

m<5 = 55°

From the diagram, m<5+m<6 = 180°

Substitute m<5 = 55° into the formula, to get m<6

55+m<6 = 180

m<6 = 180-55

m<6 = 125°

From the diagram m<6 = m<2 = 125° (corresponding angles)

Also on line e, m<9 = m<12 = 80° (vertically opposite angles)

On line f, m<14+m<16 = 180° and m<12 = m<16 = 80

m<14+80° = 180°

m<14 = 180-80

m<14 = 100°

Also on line f, m<5 = m<8 (vertically opposite angles)

Since m<5 = 55°, m<8 = 55°

Also on line e, m<10 + m<12 = 180

Since m<2 = m<10 = 125° (corresponding angle)

To get m<12,

125+m<12 = 180

m<12 = 180-125

m<12 = 55°

Also m<10 = m<14 = 125° (corresponding angle)

On line e, m<10 = m<11 = 125° (vertically opposite angle)

Also on line e, m<3 = m<11 (corresponding angle)

This shows that m<10 = m<11 = m<3 = 125°

From the above calculation the angle measure that are correct are:

m<2 = 125°, m<8 = 55° and m<14 = 100°

Solve for x: 9x-1=10x+9 How do you get x off one side and onto the other, please explain

Stels [109]

Answer:

x = -10

Step-by-step explanation:

9x-1=10x+9

9x-1+1=10x+9+1

9x=10x+10

9x-10x=10x-10x+10

-x=10

-x/-1=10/-1

x= -10

hope it's helpful ❤❤❤❤❤❤

THANK YOU.
