Answer:

c must be -4

Step-by-step explanation:

x^2 - 5x + c = 0 is a quadratic whose coefficients are a = 1, b = -5 and c = c.

The discriminant is b^2 - 4ac, and we know that b^2 - 4ac = 41.

Substituting -5 for b and 1 for a, we get:

(-b)^2 - 4(1)(c) = 41, or 25 - 4c = 41, or -4c = 16.  Thus, c must be -4, and the quadratic is

x^2 - 5x - 4

Answer:

Food is what fuels our bodies. Food is what keeps us alive, but when food is not kept fresh and safe, it can cause us to get sick or even die from food poisoning.

Answer:

13 x 158

Step-by-step explanation:

L= 2W

A= 315 sq ft^2

A= L*W

315= 2W* W

315/2= 158 = w^2

W^2= 158

W=[tex]\sqrt{158}[/tex]

W= 13

The rug should have a dimension of 15 ft wide and 21 ft long.

A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees. The two sides at each corner or vertex, meet at right angles.

Let the length of the room be l and h be the width.

So, given that,

l = 19 ft

h = 25 ft

Let w be the width of rug,

Since Cynthia can afford to buy 315 square feet of carpeting

So, area of the rug should be given as,

l*h = 315

Now to carpet the room along its dimension, each side of the width is

w + w = 2w.

So, l =25 - 2w

h = 19 - 2w

Now, ∵ l*h = 315

Put the values we get,

(25 - 2w)*(19 - 2w)  = 315

expanding we get,

4w² - 88w + 475 = 315

or, 4w² - 88w + 160 = 0

or, w² - 22w + 40 = 0

using the quadratic equation we get two solutions:

w = 2

w = 20

Since, w = 20 is greater than one of the width of the room i.e 19ft

So,we take the solution w = 2

Thus, dimensions of rug is given as,

l = 25 - 2*2 = 21 ft

h = 19 - 2*2 = 15 ft

Thus, the rug should have a dimension of 15 ft wide and 21 ft long.

Step-by-step explanation:

The sample space of the spinner is:

[tex]Sample\ Space = \{1,2,3,4,5,6,7,8\}[/tex]

So:

[tex]n(S)= 8[/tex]

All of which have the same probability.

Required

Determine the probability of 1, then 2 when spin twice

The probability of the first being 1 is:

[tex]P(1)= n(1)/n(S)[/tex]

[tex]P(1)= 1/8[/tex]

The probability of the second being 2 is:

[tex]P(2)= n(2)/n(S)[/tex]

[tex]P(2)= 1/8[/tex]

So, the required probability is:

[tex]Probability = P(1) * P(2)[/tex]

[tex]Probability =1/8* 1/8[/tex]

[tex]Probability = \frac{1}{64}[/tex]

Answer:

C. The difference quotient is 10x+5h +6, so the average rate of change is 10(1)+ 5(4) + 6 = 36

Step-by-step explanation:

The statement is the difference quotient is 10x+5h +6.

It is a measure of how much the function changed per unit, on average, over that interval. It is derived from the slope of the straight line connecting the interval's endpoints on the function's graph.

Given function:

g(x) = 5x² + 6x

interval is x= 1 to x=5

so, the average rate of change is

=10(1)+ 5(4) + 6

= 36

Answer:

(a).4.36 mph

(b) No

Step-by-step explanation:

We are given that

Jan covered distance,s1 =2 miles

Speed of Jan, a=3 mph

s2=1 mile

b=8mph

a.

We have to find the Jan' s average speed for the entire trip.

Average speed =[tex]\frac{2ab}{a+b}[/tex]

Using the formula

Average speed=[tex]\frac{2(3)(8)}{3+8}=4.36mph[/tex]

b.

Average speed with two speed

Average of Jan’s two speeds

[tex]=\frac{a+b}{2}[/tex]

=[tex]\frac{3+8}{2}=5.5 mph[/tex]

[tex]4.36\neq 5.5[/tex]

Hence, the average speed in part (a) is not equal to the average of Jan’s two speeds.

Are they correct? Is that the question? Well, the first one is correct because Slope (m) = -6/1 =-6

Equation of the line:

y = -6x + 15

When x=0, y = 15

When y=0, x = 2.5

and the other one:

Answer:

24 millilitres acid

28 millilitres base

Step-by-step explanation:

First, we need to know how many parts there are in total. We do this by adding the number of parts of acid (6) and base (7). 6+7=13

Then, divide 52 by 13 to find out how many millilitres makes up a part.

52/13=4

Then you multiply this by the number of parts for each substance.

4x6=24 millilitres acid

4x7=28 millitres base
