Answer:

C) Dilation and rotation

Step-by-step explanation:

Dilation changes the size of the shape (how big or small the shape is), rather then changing the shape itself (into a completely different shape). The other options are transformations, but they only move the shape along the graph, nothing else.  Hope this helps!

Write the equation of a line that is perpendicular to y=-0.3x+6 and that passes through the point (3,-8)
MariettaO [177]
Hey there!

First, let's look at what perpendicular means. Imagine a cross, where there's all 90 degree angles. That's exactly what we're talking about when we say perpendicular. The given equation is in slope-intercept form, where we have:

y = mx + b
where m is the slope and b is the y-intercept.

When we're writing an equation with a perpendicular slope, we use the negative reciprocal of the given slope. Thus, we can make 0.3 1/3, and take the reciprocal to make 3, and make it negative 3 as it's the negative reciprocal. Now, we know we have a line with the slope of -3 and goes through (-3, 8). We can use the x and y values in this set of points, along with the slope, to create an equation to solve for b. That gives us:

8 = -3(-3) + b
8 = -9 + b
17 = b

Now, since we have slope and y-intercept, we can write our equation as:

y = -3x + 17

Hope this helps!

The population of a town is 16,519 people. Each year the population increases by 4%. What will the town’s population be in 15 ye
snow_tiger [21]

Answer:

  29,750

Step-by-step explanation:

Each year the population is multiplied by 100% + 4% = 1.04. We want to repeat that multiplication 15 times, once for each of the 15 years. An exponent is what we use to signify (and compute) repeated multiplication. The population will be ...

  16,519 × 1.04^15 ≈ 29749.8 ≈ 29,750
