We have sec =
1/cos
Then we also have
cos^2 = 1 – sin^2
Also we have cos = sqrt (1 – sin^2)
Substitute the derived cosine function to sec then we
have
Sec = 1/(sqrt(1-sin^2)
Answer:
8x=p
Step-by-step explanation:
So 8 time the number of hours Carmen works which I used x. Then you’ll get the total.
Quadratic in equality is quadratic function that is compared to another function like: x^2+4x-1<2x-3. the answer for x must comply to both sides.
Answer:
The volume of the cone is 75.36 cm³
Step-by-step explanation:
The rule of the volume of a cone is V =
π r² h, where
- r is the length of the radius of its base
- h is the height of the cone
In the given figure
∵ The length of the radius of the cone is 3 cm
∴ r = 3 cm
∵ The length of the height of the cone is 8 cm
∴ h = 8 cm
→ Substitute the values of r and h in the rule of the volume above
∵ π ≅ 3.14
∵ V =
(3.14)(3)²(8)
∴ V = 75.36 cm³
∴ The volume of the cone is 75.36 cm³
