Answer:
a = -√3/3
b = 2√3/3
Step-by-step explanation:
Finding the slope of the tangent at C by finding the derivative:
x^2 + y^2 = 1
2x + 2y y' = 0
2y y' = -2x
y' = -2x / 2y = -x/y
So the slope = - 1/2 / √3/2
= -1/2 * 2/√3
= -1/√3
= -√3/3
Using the point-slope form of a straight line
y - y1 = m(x - x1)
y - √3/2 = -√3/3(x - 1/2)
y - √3/2 = -√3/3 x +√3/6
y = -√3/3 x + √3/6 +√3/2
y = -√3/3 x + 4√3/6
y = -√3/3x + 2√3/3
The cost to rent a bike is $28 for the first day plus $2 for each day after that. Write an explicit formula for the rental cost for n days. What is the cost of renting the bike for 8 days?
Answer:
42
Step-by-step explanation:
The explicit formula for the rental cost is =+. The cost of renting a bike for 2 days is $42.
The equation for the rental cost for n days will be 28 + 2n.
Based on the information given, the explicit formula for the rental cost for n days will be:
= 28 + (2 × n)
= 28 + 2n
Therefore, the cost of renting the bike for 8 days will be:
= 28 + 2n
= 28 + 2(8)
= 28 + 16 = 44

Aldo drove 845 miles in 13 hours.
At the same rate, how long would it take him to drive 325 miles?
Answer:
5 hours
Step-by-step explanation:
time per mile = number of hours ÷ number of miles
= 13 ÷ 845
= 1/65 hours per mile
time to drive 325 miles = 325 × time per mile
= 325 × 1/65

Unit test in science if you took it. It's question 10 four students measure the length of a paperclip whose actual length is 3.2 cm. Whose measurement is precise but not accurate? IS IT A OR B I DONT KNOW A.Samuel: 2.7, 2.7, 2.7, 2.8 B. Jose: 2.2, 2.6, 3.0, 3.3 C. Nikita: 3.1, 3.1, 3.2, 3.2 D. Anne: 2.6, 3.2, 3.2, 3.6
Answer: A.Samuel: 2.7, 2.7, 2.7, 2.8
Step-by-step explanation:
Given that actual length = 3.2cm
Samuel's score is precise but inaccurate. This is because, each of Samuel's four measurements are close to each other even though it lacks accuracy, because it is a bit far from the actual value of the measurement. Hence, of the measurements given for each of Samuel, Nikita, Jose and Anne, Samuel's score exhibits precision but inaccurate. Nikita's score is both precise and accurate

Answer:
x<4Step-by-step explanation:
x+1<5x<5-1x<4 answer.In an obstacle course, participants climb to the top of a tower and use a zip line to travel across a mud pit. The zip line extends from the top of a tower to a point on the ground 60 feet away from the base of the tower. The angle of elevation of the zip line is 20°. Estimate the length of the zip line to the nearest tenth of a foot.
about 63.9 ft
about 21.8 ft
about 175.4 ft
about 164.8 ft
Using relations in a right triangle, it is found that the length of the zip line is of about 63.9 ft.
What are the relations in a right triangle?The relations in a right triangle are given as follows:
The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.In this problem, the hypotenuse is the length of the line, considering that the base of 60 ft is adjacent to the angle of 20º, hence:
[tex]\cos{20^\circ} = \frac{60}{l}[/tex]
[tex]l = \frac{60}{\cos{20^\circ}}[/tex]
[tex]l = 63.9[/tex]
The length of the zip line is of about 63.9 ft.

Suppose that a family wants to start a college fund for their child. if they can get a rate of 5.2%, compounded monthly, and want the fund to have a value of $55,500 after 20 years, how much should they deposit monthly? assume an ordinary annuity and round to the nearest cent. a. $131.93 b. $2,662.49 c. $1,643.30 d. $3,446.64
The ordinary annuity is $135.40
We have given that the
P=55500$
rate(r)=5.2%
time (t)=20 years
What is the formula for the ordinary annuity ?The formula for ordinary annuity is:
[tex]P = A \times \frac{((1 + r)^n- 1)}{ r}[/tex]
Where,P - future value
r - rate
A - annuity payment
n - the number of years
Use the given value in the above formula of ordinary annuity so we get,
[tex]55000 = A ((1 + 0.052)^{20} - 1) / 0.052[/tex]
[tex]55000 = A * ((1.052)^{20} - 1) / 0.052[/tex]
[tex]55000 = A * (2.76 - 1) / 0.052[/tex]
[tex]55000 = A * 1.76 / 0.052[/tex]
[tex]55000 = A * 33.85[/tex]
[tex]A = 55000 / 33.85[/tex]
[tex]A = 1624.82[/tex]
Therefore the annual payment(A)=1624.82 and since year has 12 months, monthly payment is
[tex]1624.82 / 12 = $135.40[/tex]
Therefore we get the ordinary annuity is $135.40
