Find a Cartesian equation for the curve and identify it. r=8tanxsecx

1 answer:

3 0

R = 8 tan(x) sec(x)

In order to solve this, we are going to use the following:
r = sqrt(x^2 + y^2) //but in this case, we don't need this.
tan(x) = Y / X
X = r cos(x)
Y = r sin(x)

(r cos x)^2 = 8(r sin x)

x^2 = 8y

Suppose M is the midpoint of FG. Find the missing measure.

Arlecino [84]

A midpoint divides a line segment into equal halves.

The value of x is 3.4

Given that:

$FG = 11x - 15.6$

$MG = 10.9$

Since M is the midpoint, then:

$FG = 2 \times MG$

So, we have:

$11x - 15.6 =2 \times 10.9$

$11x - 15.6 =21.8$

Collect like terms

$11x =15.6 +21.8$

$11x =37.4$

Solve for x

$x =3.4$

Hence, the value of x is 3.4

Two boats started to move towards each other from two boat stations, located 30 miles apart. One boat moved at a speed of 3 mile

Ganezh [65]

Answer: 3 hours and 20 minutes

Step-by-step explanation:

3x + 2(3)x = 30

3x + 6x = 30

9x = 30

9/9 = 30/9

x = 3 1/3 hours

PLEASE HELP ME~! NEED THIS ASAP

BlackZzzverrR [31]

Answer:

Step-by-step explanation:

since y and x vary directly the equation relating them is

y = kx ← k is the constant of variation

to find k use any ordered pair from the list given

using x = 4 when y = - 2, then

k = $\frac{y}{x}$ = $\frac{-2}{4}$ = - 0.5 → B
