Answer:

Axis of symmetry is x = -4

Step-by-step explanation:

h(x)= 5x^2+40x+ 64

Use the formula for axis of symmetry: x = -b/(2a)

Here, a = 5, b = 40, c = 64

x = -40/(2*5) = -40/10 = -4

Axis of symmetry is x = -4

The Tonga Trench is at an elevation of 35,702 feet below sea level. The South Sandwich Trench is at an elevation of 23,737 feet

Svetach [21]

Both elevations or numbers are already expressed as a rational number. This is because a rational number is defined as a number that can be expressed as a quotient or fraction of two numbers:

p / q

Since in this case, q may be equal to 1, then both are rational numbers.

Solve Problems Using Division David and Jake a are making cookies. They each get 2 rolls of cookie dough and they are cutting up

trapecia [35]

Answer:

<u>David will have the most cookies and he will have two cookies more than Jake</u>

Step-by-step explanation:

1. Let's calculate how many cookies will David cut with his cutter, this way:

Number of cookies = Rolls of cookie dough/Size of the segment

Replacing with the values we know:

Number of cookies = 2/(1/8)

Number of cookies = 16

2. Let's calculate how many cookies will Jake cut with his cutter, this way:

Number of cookies = Rolls of cookie dough/Size of the segment

Replacing with the values we know:

Number of cookies = 2/(1/7)

Number of cookies = 14

<u>David will have the most cookies and he will have two cookies more than Jake</u>
