ivann1987 [24]

Answer:

15

Step-by-step explanation:

The slope = \frac{change in y}{change in x} =\frac{38+4}{25+3} =\frac{42}{28} =\frac{3}{2}

This means that when the caterpiller moves 2 units to the right, it moves 3 units up.  Since 42/3 = 28/2 = 14. this happens 14 times from (-3, -4) to (25, 28).   Counting the starting point (-3, -4) we get 14 + 1 = 15 points with integer coordinates.

At the Denver International Airport, planes must clear a mountain that is 1000 feet tall that is a horizontal distance of 2800 f
Readme [11.4K]

Answer:

19 degrees

Step-by-step explanation:

Will have a triangle with horizontal distance being 2800, and vertical being 1000 feet. Angle between the horizontal and hypotenuse is what we are looking for.

Thus it's a tangent function.

SOH

CAH

TOA <-----

Tangent is the opposite / adjacent

So we will be looking at doing an Arctan to find the angle.

Arctan α = \frac{1000}{2800}  = 19.29 degrees. Round to the nearest whole degree would be 19 degrees due to being less than .50

Your answer is 19 degrees

4x^2+2x-5-3x and 6x^2-x+3-2x^2-8<br><br> Are these two expressions equal? Show how you know
aivan3 [116]

Step-by-step explanation:

Simply Equation 1

R. H. S

6x^2 -x +3-2x^2-8

==> 6x^2-2x^2 -x +3-8

==> 4x^2-x-5 .....(1)

Simply equation 2

L. H. S

4x^2+2x-5-3x

==> 4x^2 +2x-3x-5

==> 4x^2-x-5 ....(2)

Since here, RHS = LHS

both eqn (1) = eqn(2)

hence they are equal.
