Answer:

Yes they are equal

Step-by-step explanation:

You can treat them like fractions and 24/32 =1/3

and 18/24 = 1/3

These can then put back into the ratios 1:3 and 1:3 which is the same

Yes 18:24 because I did the math on my computer

Your answer would be option B. 2y² - y - 6 = 0. This is because if you were to substitute x = y² - 1 into the equation 2x - y = 4, you would get 2(y² - 1) - y = 4, which expands into 2y² - 2 - y = 4, and then simplifies to 2y² - y - 6 = 0.
I hope this helps!

What is the equation in point slope form of the line that passes through the point (−1, −3) and has a slope of 4?

Dmitry_Shevchenko [17]

The point-slope form:

$y-y_1=m(x-x_1)$

We have the slope m = 4 and the point (-1, -3). Substitute:

$y-(-3)=4(x-(-1))\\\\\boxed{y+3=4(x+1)}$

To find the height of a pole, a surveyor moves 160 feet away from the base of the pole and then, with a transit 6 feet tall, mea

Artyom0805 [142]

Answer:

306.8 feet

Step-by-step explanation:

Refer the attached figure .

A surveyor moves 160 feet away from the base of the pole i.e. ED = 160 m

Referring the image .

AC=ED=160 m

A transit i.e. AE is 6 feet tall.

AE = CD=6 feet

With a transmit the angle of elevation to the top of the pole to be 62° i.e. ∠BAC = 62°

To Find BC , use tigonometric ratio.

$Tan\theta = \frac{Perpendicular}{Base}$

$Tan 62^{\circ}=\frac{BC}{AC}$

$Tan 62^{\circ}=\frac{BC}{160}$

$1.88*160=BC$

$300.8=BC$

Now, the height of the pole = BC+CD =300.8+6=306.8 feet

Hence the height of the pole is 306.8 feet
