valkas [14]

Answer:

x-ints: (2,0) & (4,0)

y-int: (0,-8)

vertex: (3,1) *highest point of the graph

line of symmetry: x = 3 *x-value in the middle of x-ints

a value is -# *if parabola points done it's negative, if it points up it's positive

Can someone please help me on this question

vovikov84 [41]

A. The scientific notation for 50,000,000 is 5 x 10^7 (to the 7th power)

B. After squaring 50,000,000 you'll get <span>2500000000000000. In </span>scientific notation, this is 2.5 x 10^15 (to the 15th power).

C. I think what it's asking is how I solved part B... this could be wrong, double check it. I solved it by multiplying 50,000,000 x 50,000,000 and then converting the product into scientific notation.

Hope this helps, if you have more questions, message me or comment under this post!

Question is Incomplete, Complete question is given below.

Mr. Jablonski's class is making fudge for a bake sale. Mr. Jablonski

has a recipe that makes 3/4 pound of fudge. There are 21 students in

the class. Each student uses the recipe to make one batch of fudge.

How many pounds of fudge do the students make?

Answer:

student made $\frac{63}{4} \ lbs \ OR \ 15 \frac{3}{4}\ lbs \ OR \ 15.75\ lbs$ of fudge.

Step-by-step explanation:

Given:

Mr. Jablonski recipe makes 3/4 pound of fudge.

Number of student in class = 21 students.

Each student uses the recipe to make one batch of fudge.

Hence to calculate Total amount of fudge student made we will multiply the amount of fudge used in recipe with Number of students.

Total amount of fudge student made = amount of fudge used in recipe × Number of students.

Total amount of fudge student made = $\frac{3}{4}\times21 = \frac{63}{4} \ lbs =15 \frac{3}{4}\ lbs = 15.75\ lbs$

Hence the student made $\frac{63}{4} \ lbs \ OR \ 15 \frac{3}{4}\ lbs \ OR \ 15.75\ lbs$ of fudge.
