a. -squr3/2
b. -1/2
c. 1/2
d. squr3/2
Answer:
B -1/2
Step-by-step explanation:
The given trigonometric expression can be evaluated as -1/2.
What are trigonometric ratios?The trigonometric ratios are defined for a right angled triangle.
The example of these ratios are sin, cos, tan, cosec, sec and cot.
The trigonometric ratios are useful in determining the heights and distances of the large objects.
The given trigonometric expression is as below,
cos(11π/21)cos(π/7) - sin(11π/21)sin(π/7)
Suppose, A = 11π/7 and B = π/7
Then, the given expression can be written as,
cosAcosB - sinAsinB
As per the trigonometric identity cos(A + B) = cosAcosB - sinAsinB.
Then, the given expression can be written as,
⇒ cos(11π/21)cos(π/7) - sin(11π/21)sin(π/7) = cos(11π/21 + π/7)
⇒ cos(2π/3) = -1/2
Hence, the exact value of the given expression is -1/2.

y + 1 = -2x-3 in standard form *
Answer:
y = -2x - 4
Step-by-step explanation:
y + 1 = -2x - 3
Subtract 1 from both sides to get the y by itself
y = -2x - 3 - 1
Simplify (Combine Like terms)
y = -2x - 4

Find the area of a circle with a radius of 5 feet. Round your answer to the nearest tenth. Find the area of a circle with a diameter of 56 millimeters. Round your answer to the nearest hundredth.
Case 1 :
Radius, r = 5 feet.
Area,
[tex]A=\pi r^2\\\\A = 3.14\times 5^2\ feet^2\\\\A = 78.5\ feet^2[/tex]
Case 2 :
Diameter, d = 56 mm.
So, radius, r = d/2 = 28 mm.
Area,
[tex]A = 3.14\times 28^2\ mm^2\\\\A = 2461.76\ mm^2[/tex]
Hence, this is the required solution.

Find the length of arc ab. Need help!!!
Answer:
12.4cm (rounded to nearest tenth)
Step-by-step explanation:
To find the length of an arc, you have to find the circumference of the full circle itself multiplied by the angle of the arc over 360°. The circumference of a circle is pi × r × 2.
Length of arc = [tex]\frac{90}{360}[/tex] × 3.14 × 7.9 × 2
= 12.403
≈ 12.4cm (rounded to nearest tenth)

Answer:
280 miles in allStep-by-step explanation:
Step one:
given data
we are told that the team traveled 148miles south.
and also they traveled 132miles north.

and ig the question is what is the scientific notation of 0.0021
Answer:
0.0021 in scientific notation is [tex]\mathbf{2.1 x 10 ^ {-3}}[/tex]
Step-by-step explanation:
We need to write 0.0021 in scientific notation.
Scientific Notation: A number expressed in scientific notation is written when numbers between 1 to 10 are multiplied by a power of 10.
In the given example 0.0021 our decimal will be shifted to the right 3 digits and the power will be negative 3 (-3)
So, 0.0021 in scientific notation is [tex]\mathbf{2.1 x 10 ^ {-3}}[/tex]

solve step by step and have a well explanation.
if you get this correct and solve this question step by step with a good explanation then i will mark you brainliest!
Answer:
v = 2/5 Or v = 0.4
Step-by-step explanation:
12/5 = 6v
to isolate V divide both sides by 6
(12/5) : (6)= 6v : (6)
For the left side because there is a fraction when you devide you change it into multiplication, flipping the addent and quotient so you’ll have
12/5 * 1/6 (you semplify the cross numbers) you’ll have 2/5
on the right side the 6 cancel each other. Because 6/6 = 1. so you will have 1v which is v.
2/5 = v
or decimal form
0.4 = V
