Answer:
Step-by-step explanation:
A vertical stretch of a function means the output values have changed by a factor of 3 or multiplication by 3. Recall, an exponential function has the basic form
.
If our equation is , then a=1. To stretch it vertically by a factor of 3, we multiply a by 3. So 1(3)=3. The value of a now becomes 3.
The answer is A hope this helps
Answer:
The kind of triangle that will form the shape of her flower bed is;
A scalene triangle
Step-by-step explanation:
In creating the triangular flower bed, the length of the scraps Mariah uses are;
The length of one scrap = 2.2 feet long
The length of the second scrap = 4.25 feet long
The length of the third scrap = 5.75 feet long
From the given length of the scraps, the kind of triangle that will form the shape of her flower bed is a scalene triangle
A scalene triangle is a triangle that the length of all the three sides are different and the measures of the three interior angles of the triangle are therefore also different

Set-Builder Notation:
{x|x≠0,7}
Answer:
x ≥ 15
Step-by-step explanation:
First you need to make an equation for this. If he already has $50 and needs <u>at least</u> 500 and deposits $30 per day we can put the equation as 30x + 50 ≥500. The reason we put a greater than or equal sign (≥) rather than the less than or equal sign (≤) is because Fred needs <u>at least</u> meaning you can have exactly or 500 exactly. To solve this you would have to do inverse operation and subtract 50 on both sides. You should have 30x≥450. Then divide 30 on both sides. Your answer should be x ≥ 15.
