Answer:
1.5 sec by meters
Step-by-step explanation:
90 meters/60 sec=1.5
Darrel walks at a unit rate of 1.5 m/sec.
What is speed?Speed is defined as the rate of change of position in unit time.
Mathematically,
Speed = Distance/Time
Now it is given that,
Distance in walk by Darrell = 90 meters
Time taken by Darell to walk 90 meters = 60 seconds
Therefore Speed i.e unit rate of walk is given as,
Unit rate of walk = Distance in walk by Darrell / Time taken by Darell to walk 90 meters
⇒ Unit rate of walk = 90/60 m/sec
⇒ Unit rate of walk = 3/2 m/sec
⇒ Unit rate of walk = 1.5 m/sec
Thus, Darrel walk at a unit rate of 1.5 m/sec.

1. Write a quadratic equation for the parabola that passes through the
point (2, -3) with roots (-6, 0) and (4,0).
The quadratic equation with the given conditions is:
[tex]f(x) = \frac{3}{16}(x^2 + 2x - 24)[/tex]
The standard form of a quadratic equation with roots [tex](x_1,0)[/tex] and [tex](x_2,0)[/tex] is given by:
[tex]f(x) = a(x - x_1)(x - x_2)[/tex]
In which a is the leading coefficient.
In this problem, the roots are [tex]x_1 = -6, x_2 = 4[/tex], thus:
[tex]f(x) = a(x - (-6))(x - 4)[/tex]
[tex]f(x) = a(x + 6)(x - 4)[/tex]
[tex]f(x) = a(x^2 + 2x - 24)[/tex]
It passes through point (2,-3), which means that when [tex]x = 2, f(x) = -3[/tex], and this is used to find a.
[tex]a(2^2 + (2)(2) - 24) = -3[/tex]
[tex]-16a = -3[/tex]
[tex]a = \frac{3}{16}[/tex]
Thus, the equation is:
[tex]f(x) = \frac{3}{16}(x^2 + 2x - 24)[/tex]

Is 53.7. 104 written in scientific
notation? Why or why not?
Assuming the expression is [tex]53.7 * 10^{4}[/tex].
Answer:
No
Step-by-step explanation:
Scientific notation is where a number is written in the form [tex]a*10^{b}[/tex] where [tex]a[/tex] and [tex]b[/tex] are integers AND [tex]1<=a<10[/tex].
In our expression, [tex]53.7>=10[/tex], so it doesn't satisfy the requirements of scientific notation.
So, the answer is [tex]\boxed{no}[/tex], it's not written in scientific notation.
mandle is making 15 cups of fruit salad . what ration of grapes to blueberries should she use?
Answer:
12:3
Step-by-step explanation:
The first thing you should do for this case is to graph the data you have in the statement to see the relationship between grapes and blueberries.
The function represented by the table is
y = 0.25x
Then, as Mandie is making 15 glasses of fruit salad, we have:
y + x = 15
We have two equations and two unknowns that we must solve.
y = 0.25x
y + x = 15
Resolving
For x:
0.25x + x = 15
1.25x = 15
x = 15 / 1.25 = 12
For y:
y = 0.25x = 0.25 (12) = 3
Answer
The ratio of grapes to blueberries she should use is 12: 3

Explain how you can check that the value you found for g is correct. If your check does not work, does that mean that your result is incorrect? Explain. -----------------------------------------------------------------------------------------------------------------------------
Choose the correct explanation below.
A.
Substitute the value for g on one side of the equation to check the answer. If the check does not work, either the answer is incorrect or there were errors made when checking.
B.
Substitute the value for g on one side of the equation to check the answer. If the check does not work, then the answer must be incorrect.
C.
Substitute the value for g on both sides of the equation to check the answer. If the check does not work, either the answer is incorrect or there were errors made when checking.
D.
Substitute the value for g on both sides of the equation to check the answer. If the check does not work, then the answer must be incorrect.
The best explanation to given when checking for the value of g that you have found is:
C. Substitute the value for g on either sides of your equation to check the answer. If the check does not work, it is either the answer is incorrect or there were errors you made when checking.
After solving for a variable in an equation, we can cross check to know if our answer is correct or not.
This can be done by plugging in or substituting the value of the variable g into the equation. In most cases, you will find the variable on both sides.
When you substitute, the value on the left must be equal to the value on the right. If during your check, the value on the left does not equal the value on the right, it simply means the check does not work.
Two things might result to a check not working:
the answer is not correct, oryou made a mistake while checking.Therefore, the best explanation to given when checking for the value of g that you have found is:
C. Substitute the value for g on either sides of your equation to check the answer. If the check does not work, it is either the answer is incorrect or there were errors you made when checking.

Answer:
a. $77.5 for 5 tickets
b. You can by 8 tickets with $130
Step-by-step explanation:
Answer:
a) $77.50
b) 8 tickets
Step-by-step explanation:
a) C(x) = 17.5(x) - 10
C = 17.5(5) - 10
C = $77.50
b) C(x) = 17.5(x) - 10
130 = 17.5(x) - 10
130 + 10 = 17.5(x) -10 + 10
140 = 17.5(x)
140/17.5 = (x)
