Step-by-step explanation:
A.
15/5 = 3, 21/7 = 3 -- scale factor is 1/3 since he must divide by 3 to get the side lengths for the photo card
B.
Area = width*length, and scale factor is 5. Therefore, the new width is (15*5) and the new length is (21*5), so the new area is 15*5*21*5 = 15*21*5² = 15*21*25 = 315*25 = 7875 in²
It’s C)21/20 because for tan you do the opposite side over the adjacent. SOHCAHTOA (sin: opposite/hypotenuse cos: adjacent/hypotenuse tan: opposite/adjacent)
Answer:
Since the 5 in 357 is in the tens digit, it is 5*10=50, and the 5 in 465 is in the ones digit, so it is 5*1=5. 5≠50
Your center would be (3,-4)
Hello :
note :
<span>
<span>an equation of the circle Center at the
A(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
</span></span>in this exercice : a =0 b = 0 r =8
<span>the equation of the circle is : x²+y² = 64</span>
