Answer:

m = 24

Step-by-step explanation:

m + 7° + 2m + 11° = 90°

3m + 18° = 90°

3m = 90°- 18°

3m = 72

(divide both sides by 3)

therefore : m = 24

90-11=79
79=2m+m+7
79=3m+7
79-7=3m
72=3m
72/3=3m/3

24=m

Write the equation of the circle in standard form: Center (7,0) R=1

Mice21 [21]

Answer:

$(x-7)^2+y^2=1$

Step-by-step explanation:

Hi there!

Equation of a circle: $(x-h)^2+(y-k)^2=r^2$ where the circle is centered at (h,k) and the radius is r

1) Plug in the given center (7,0)

$(x-7)^2+(y-0)^2=r^2\\(x-7)^2+y^2=r^2$

2) Plug in the radius (1)

$(x-7)^2+y^2=1^2\\(x-7)^2+y^2=1$

I hope this helps!

Need help plz very much

andrew-mc [135]

Answer:

Step-by-step explanation:

Remember that when we are dividing two exponents with the same base (here, it's 13), we can subtract the values of the powers:

$\frac{a^m}{a^n} =a^{m-n}$

So, here, we have $\frac{13^{10}}{13^7}$ , so we subtract 7 from 10:

$\frac{13^{10}}{13^7}=13^{10-7}=13^3$

Thus, 3 should go in the box.
