Answer:
Circumference : 18.84 inches
Radius: 3 inches
Answer:
The cross multiplication would be 10(350) = 22(x).
Step-by-step explanation:
We would first convert meters to centimeters. There are 100 cm in a meter; this means 3.5 m = 3.5(100) = 350 cm.
The ratio of the height to base of the model is 10/22. The ratio of the playhouse would then be x/350. This gives us
10/22 = x/350
Cross multiplying, we would have 10(350) = 22(x).
Answer:
D. It shrinks the graph horizontally to 1/4 the original width.
Step-by-step explanation:
f(px): |p|>1 horizontal compression (x,y) -> (x/p , y)
Answer:

Step-by-step explanation:
First, you need to get the equation into y = mx + b form, like this:
Add y to both sides to get y + 2x − 5= 0
Then subtract 2x to get y - 5 = -2x
Add 5 to get y = -2x + 5
Now we know the slope is -2, or -2/1.
A line that is perpendicular to it has a slope that is the first line's slope's opposite reciprocal. This means flip the fraction upside down and change the sign, which gives you positive 1/2.
