Let's solve for r.
y = −4r − 3
Step 1: Flip the equation.
−4r − 3 = y
Step 2: Add 3 to both sides.
−4r −3 + 3 = y + 3
−4r = y + 3
Step 3: Divide both sides by -4.
−4r y+3
— = —
−4 -4

r = −1 -3
— y + —

Convert 118 to radian measure.<br><br> Round your answer to the nearest hundredth.
dangina [55]

Answer:

2.06 rad

Step-by-step explanation:

To change degree measure to radian measure

radians = degrees × \frac{\pi }{180} , then

radians = 118 × \frac{\pi }{180}

            = \frac{118(\pi )}{180} ≈ 2.06 rad ( to the nearest hundredth )

What is the value of 4x^2+5x when x=1
erastovalidia [21]
So the answer to this equation is 9
to find the answer we first need to substitute the x for 1
so the equation would be 4×1^2+5*1
so now we simplify the equation so it would be 4+5×1
and 4+5*1 simplified is 4+5
and 4+5=9

NEED ANSWER
grandymaker [24]

Answer:

\frac{x^{2}}{144}+\frac{y^{2}}{79.995}=1

Step-by-step explanation:

An ellipse centered a point (h,k) has the following formula:

\frac{(x-h)^{2}}{a^{2}}+\frac{(y-k)^{2}}{b^{2}}=1

The distance between foci is:

2\cdot c = \sqrt{[8-(-8)]^{2}+(0-0)^{2}}

2\cdot c = 16

c = 8

The center of the ellipse is:

C(x,y) = (-8 + 8, 0 + 0)

C(x,y) = (0,0)

The known vertex is on the horizontal axis of the ellipse. Then, the length of the semi-major axis is:

a = \sqrt{(12-0)^{2}+(0-0)^{2}}

a= 12

The length of the semi-minor axis is given by the following expression:

c =\sqrt{a^{2}-b^{2}}

b = \sqrt{a^{2}-c^{2}}

b = \sqrt{12^{2}-8^{2}}

b \approx 8.944

The equation of the ellipse is:

\frac{x^{2}}{144}+\frac{y^{2}}{79.995}=1

Simplify the quotient. Write the answer in sn.
MA_775_DIABLO [31]

Answer:

2.4*10^4

Step-by-step explanation:

write in scientific notation

first i would simplify the 3.6/1.5

=2.4

then you get (2.4*10^7)/10^3

formula: (m^x)/(m^y)= m^(x-y)

(2.4*10^7)/10^3

=2.4*10^(7-3)/1

=2.4*10^4
