I will solve one for you to get you a idea so next u can solve all
To know whether line is tangent toa circle or not we should know that that line is a tangent line of a circle if it intersects circle at single point.
and this will always be perpendicular at radius
so in problem
1)
diameter is given 7.5
and u can see they make a right triangle ABC if that is perpendicular so segment AB is tangent to a circle.
Lets see by applying <span>Pythagorean Theorem
</span>this is method we can say that this is in fact a right triangle
a^2=b^2=c^2
a,b are shorter side c is longer side
(7.5)^2+(8)^2=(17)^2
56.25+64=289
120.25=289
both are not equal so they are not forming right triangle so segment AB is not a tangent line.
The height of larger will be 3 cm
As,
= ∛8 cm³ * 27 cm³ / (2 cm) ³
= 3cm
Answer:
A. whether a woman took hormones.
B. whether to woman in the study had a heart attack.
D. access to health care
Step-by-step explanation:
The study conducted to observe the menopausal woman must be supported with their health history. Some woman may have menopause at an early age while other go towards this at a later age. This can be due to smoking, hormone intake, severe diseases like heart attack or cancer and their routine health checkup details. There variables must be observed and included in experiment to reach a conclusion.
Answer: B
Step-by-step explanation:
The shorter arrow is the hour while the longer arrow is the minutes. Since the shorter arrow is between one and two, the hour would be one. The clock goes by minutes, and each of the dashes are a minute. There are 60 dashes for 60 minutes. From 12 to 1, it's 5 minutes. It's the same for 1 to 2, 2 to 3, and so on. So 7 × 5 is 35 + 4 is 39, where the longer arrow is placed. So the time is 1:39.
