Answer:
h(0)=10
h(4)=16
Step-by-step explanation:
for h(0) you would need to do the second equation because it is within the bounds of the variable.
h(0)= 2x^2 - 3x + 10
anything times 0 is 0
so 2(0)^2 - 3(0) + 10=
0-0+10=
10
h(4) would use the third equation since it's the only one that agrees with the variable 4

Please and thank you!
Answers
Answer:
Step-by-step explanation:
Both equations have -7y. You can eliminate them by subtracting one equation from the other:
Multiply equation 1 by -1, then add it to equation 2:
-2x + 7y = 74
3x - 7y = -83

Jamal is making a snack mix that contains only pretzels and nuts. For every ounce of nuts, he will use 2 ounces of pretzels.
How many ounces of pretzels and how many ounces of nuts does he need to make 45 ounces of snack mix?
Answers
Answer:
Pretzels: 30 ounces, Nuts: 15 ounces
Step-by-step explanation:
Trust me.
Number of ounces of nuts = 30
Number of ounces of pretzels = 15
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Jamal is making a snack mix with pretzels and nuts.
And, For every ounce of nuts, he will use 2 ounces of pretzels.
Total number of snake mix = 45 ounces
Now,
Let number of ounces of pretzels = y
Let number of ounces of nuts = x
So, We can formulate;
⇒ x = 2y ... (i)
And, x + y = 45 .... (ii)
Substitute the value of x in equation (ii) , we get;
x + y = 45
2y + y = 45
3y = 45
y = 15
And,
x + y = 45
x + 15 = 45
x = 30
Therefore,
Number of ounces of nuts = 30
Number of ounces of pretzels = 15

Sec is just Cos flipped
A rectangular storage container without a lid is to have a volume of 10 m3. The length of its base is twice the width. Material for the base costs $15 per square meter. Material for the sides costs $9 per square meter. Find the cost (in dollars) of materials for the least expensive such container. (Round your answer to the nearest cent.)
Answers
Answer:
The least expensive cost = $245.32
Step-by-step explanation:
From the information:
Volume of the rectangular container = 10 m²
Assume the width of the container is = w
The base = 2 × width
= 2(w)
Volume = height × base × width
10 = h × 2w × w
[tex]h = \dfrac{10}{2w^2}[/tex]
[tex]h = \dfrac{5}{w^2}[/tex]
Now, to calculate the area of the base; we have:
[tex]Area = length \times width[/tex]
[tex]Area = 2w \times w[/tex]
[tex]Area = (2w^2) \ m^2[/tex]
[tex]Cost \ of \ base = 15 * 2w^2[/tex]
Cost of base = [tex]30w^2[/tex] --- (1)
[tex]Area \ of \ side = 2 ( height \times length ) + 2( height \times width) \\ \\ = 2 (h \times 2w) + 2(h\times w) \\ \\ = 4hw + 2hw \\ \\ = 6 hw \\ \\ = 6 \times \dfrac{5}{w^2} \times w \\ \\ Area = \dfrac{30 }{w} \ m^2[/tex]
Let's not forget that the cost of the sides = $9 per m²
Thus; the cost of the sides will be [tex]= \$ 9 \times \dfrac{30}{w}[/tex]
the cost of the sides [tex]= \dfrac{\$270}{w}[/tex]
Thus the total cost = cost of base = cost of sides
[tex]C(w) = 30w^2 + \dfrac{270}{w}[/tex]
By differentiation;
[tex]C'(w) = \dfrac{dC}{dw} \\ \\ = 30 \times 2w + 270 ( \dfrac{-1}{w^2}) \\ \\ C'(w) = 60 w - \dfrac{270 }{w^2} \\ \\[/tex]
[tex]\text{To determine the minimum cost:} \\ \\ C'(w) = 0 \\ \\ So, 60 w - \dfrac{270}{w^2}= 0 \\ \\ \text{By integrating w.r.t w} \\ \\ w ( 60 - \dfrac{270}{w^3}) =0 \\ \\ \implies 60 - \dfrac{270}{w^3} \\ \\ w^3 = \dfrac{270}{60} \\ \\ w^3 = \dfrac{9}{2} \\ \\ w = (\dfrac{9}{2})^{1/3} \\ \\ w = 1.6509 \ m[/tex]
From; [tex]C(w) = 30w^2 + \dfrac{270}{w}[/tex]
[tex]Cos t = \dfrac{30 w^3+ 270}{w} \\ \\ =\dfrac{30 (\dfrac{9}{2})+ 270}{1.6509} \\ \\ = \dfrac{135+270}{1.6509} \\ \\ = \dfrac{405}{1.6509} \\ \\ \mathbf{Cost = \$245.32}[/tex]

A sewing project requires 6 1/8 yd of material that sells
for $4 per yard and 3 1/4 yd of material that sells for $3 per
yard. Choose the best estimate for the cost of the project:
a. Between $30 and $40
b. Between $20 and $34
c. Between $36 and $40
d. Between $33 and $40
Answers
The best estimate for the cost of the sewing project is between $30 and $40. Hence option 'a' is correct.
Use the concept of fraction defined as:
A fraction is a part of the whole number and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called a fraction.
It can be written as the form of [tex]p : q[/tex], which is equivalent to p / q.
Given that,
The sewing project also requires 3 1/4 yards of material selling for $3 per yard.
To calculate the cost of the sewing project:
Compute the cost of each type of material separately and then add them together.
For the first type of material:
We need [tex]6\dfrac{1}{8}[/tex] yards, which is equivalent to 6.125 yards.
The cost of this material would be,
6.125 x 4 = $24.50
For the second type of material:
We need [tex]3\dfrac{1}{4}[/tex] yards, which is equivalent to 3.25 yards.
The cost of this material would be,
3.25 x 3 = $9.75.
Now, add the costs of the two types of materials together:
$24.50 + $9.75 = $34.25.
Hence,
The cost of the project would be between $30 and $40,
Which is option a.

A random sample of 18 sales receipts for internet sales results in a mean sale amount of $96.70 with a standard deviation of $20.25. Using this data, find the 98% confidence interval for the true mean difference between the mean amount of mail-order purchases and the mean amount of internet purchases.

Answer:
−35.713332 ; 0.313332
Step-by-step explanation:
Given that:
Sample size, n1 = 11
Sample mean, x1 = 79
Standard deviation, s1 = 18.25
Sample size, n2 = 18
Sample mean, x2 = 96.70
Standard deviation, s2 = 20.25
df = n1 + n2 - 2 ; 11 + 18 - 2 = 27
Tcritical = T0.01, 27 = 2.473
S = sqrt[(s1²/n1) + (s2²/n2)]
S = sqrt[(18.25^2 / 11) + (20.25^2 / 18)]
S = 7.284
(μ1 - μ2) = (x1 - x2) ± Tcritical * S
(μ1 - μ2) = (79 - 96.70) ± 2.473*7.284
(μ1 - μ2) = - 17.7 ± 18.013332
