Answer:

Step-by-step explanation:

The standard form of a parabola is

[tex]y=ax^2+bx+c[/tex]

If we know the y intercept is (0, 400), that means that when x = 0, y = 400. That allows us to begin by finding c:

[tex]400=a(0)^2+b(0)+c[/tex] and c = 400.

Now to find a and b. Using the fact that the vertex is (1, 405), we know that h is 1 and k is 405. If

[tex]h=\frac{-b}{2a}[/tex] and h = 1, then

[tex]1=\frac{-b}{2a}[/tex] and

2a = -b so

b = -2a.  Save that for a minute or two.

If

[tex]k=c-\frac{b^2}{4a}[/tex] and k = 405, then

[tex]405=400-\frac{(-2a)^2}{4a}[/tex] and

[tex]405=400-\frac{4a^2}{4a}[/tex] and

405 = 400 - 4a and

5 = -4a so

[tex]a=-\frac{5}{4}[/tex]

We will use that a value now to find the value of b.  If b = -2a, then

[tex]b=-2(-\frac{5}{4})[/tex] and

[tex]b=\frac{10}{4}[/tex]

Writing our parabolic equation now:

[tex]y=-\frac{5}{4}x^2+\frac{10}{4}x+400[/tex]

Finding the x-intercepts is just another way of saying "factor this quadratic" so we will begin that by setting the quadratic equal to 0:

[tex]0=-\frac{5}{4}x^2+\frac{10}{4}x+400[/tex] and who hates all those fractions more than I do? Probably nobody, so we are going to get rid of them by multiplying everything by 4 to get

[tex]-5x^2+10x+1600=0[/tex] Assuming you can throw that into the quadratic formula to solve for the 2 values of x where y = 0, you'll find that the x-intercepts are

x = -16.91647287 and 18.91647287

Answer:

60%.

Step-by-step explanation:

The the percent increase in the number of games the Tigers won from last year to this year is; 60%

We are told that the tigers won 12 games last year.

Now this year the tigers won 20 games.

Thus, if the total number of games to be won is n, then;

Last year = 12/n

This year = 20/n

Thus,

Percentage increase = [(12/n)/(20/n)] * 100%

Percentage increase = 12/20 * 100%

Percentage increase = 60%

Answer:

SR =3

Step-by-step explanation:

SR + RQ = SQ

2x+23 + x+21 = 14

Combine like terms

3x+44 = 14

Subtract 44 from each side

3x+44-44= 14-44

3x = -30

Divide each side by 3

3x/3 = -30/3

x = -10

SR = 2x+23 = 2(-10)+23 = -20+3 =3

Answer: 3

Step-by-step explanation:

We can start by making an equation.

Since we know the total length of SQ we can add SR + RQ to equal SQ.

[tex](2x+23)+(x+21)=14[/tex]

The parenthesizes are not necessary but they help for understanding the parts of the equation.

We will remove the parenthesizes and combine like terms.

[tex]3x+44=14\\[/tex]

Now subtract 44 from both sides to cancel it out from the side with x.

[tex]3x=-30[/tex]

Now divide by 3 to isolate x.

[tex]x=-10[/tex]

So x = -10.

Now we can plug in the value of x into SR.

[tex]2(-10)+23 = SR[/tex]

Solve

So SR = 3

Step-by-step explanation:

We need to find how long Sofia spent mowing and then compare with the time Sean spent.

Sean mowed his lawn in 2 ½ hours.

Sofiia mowed her lawn for ¼ hours, then stopped. She did this 7 times. This means:

1/4 * 7 = 7/4 hours = [tex]1\frac{1}{4}[/tex] hours

Therefore, Sean spent more time mowing his lawn.

Answer:

The new ribbon is 511.85 meter long.

The total cost Rs. 6142.2

Step-by-step explanation:

First of all we convert all lengths to the standard unit that is meter.

0.5 km =500 meter

1005 cm = 10.05 meter

1800 mm = 1.8 meter

total length in meters

500+10.05+1.8= 511.85

total cost at the rate of Rs. 12 per meter will be

511.85×12=6142.2

The length of the new ribbon is 511.85m.

The cost of the single ribbon formed is Rs. 6142.20.

Common units of length are Millimeter(mm), centimeter(cm), meter(m), and kilometer(km).

The S.I. unit of length is the meter.

All units relate to the meter in the following way:

1000mm = 1m ⇒ 1mm = 1/1000m ⇒ 1mm = 0.001m

100cm = 1m ⇒ 1cm = 1/100m ⇒ 1cm = 0.01m

1km = 1000m

The lengths of three pieces of ribbon are given as 0.5km, 1005cm, and 1800mm.

We are asked to find the length of the ribbon formed by joining these 3 ribbons.

To find the total length, we need to add them, but to add we need lengths in equal units. So we convert the three lengths into the common unit meter.

0.5km = 0.5 * 1000 m = 500m (∵ 1km = 1000m)

1005cm = 1005 * 0.01m = 10.05m (∵ 1cm = 0.01m)

1800mm = 1800 * 0.001m = 1.8m (∵ 1mm = 0.001m)

∴ The length of the new ribbon = 500 + 10.05 + 1.8 m = 511.85m.

Cost of the ribbon = Rs. 12 per meter

∴ Cost of the single ribbon formed = Rs. 12 * 511.85 = Rs. 6142.20.

Vertex : (1, -9)

Axis of symmetry : x = 1

x-intercepts : (-2, 0), (4, 0)

y-intercept : (0, -8)

Step-by-step explanation:

Quadratic function to be graphed is,

h(x) = (x - 1)² - 9

By comparing this equation with the vertex form of the parabola,

f(x) = (x - h)² + k

here (h, k) is the vertex of the parabola.

Therefore, vertex of the parabola to be graphed will be (1, -9)

Since coefficient of highest degree term (x²) is positive, parabola will open upwards.

Axis of symmetry of the parabola,

x = 1

For x-intercepts,

(x - 1)² - 9 = 0

(x - 1)² = 9

(x - 1) = ±3

x = 1 ± 3

x = -2, 4

Points of x-intercepts will be (-2, 0), (4, 0).

For y-intercepts, (x = 0)

h(x) = (0 - 1)² - 9

      = 1 - 9

      = -8

So the point of y-intercept will be (0, -8).

Answer:

Vertex : (1, -9)

Axis of symmetry : x = 1

x-intercepts : (-2, 0), (4, 0)

y-intercept : (0, -8)

Step-by-step explanation:

Here first even number is 26

and last even number is 126

we add both of these and divide the sum by 2

26 + 126 = 152

152/2 = 76

now there are total 51 even number from 26 to 126.

so sum of even numbers from 26 to 126 is

sum = 76 × 51 = 3876

Answer:

3,876

Step-by-step explanation:

Sequence of even numbers from 26 to 126 is given as:

26, 28, 30, 32, 35..............,126

Here, a = 26, d = 2, [tex] a_n = 126[/tex]

[tex] \because a_n = a + (n-1)d\\

\therefore 126 = 26 + (n-1) \times 2\\

\therefore 126 - 26 = 2(n-1) \\

\therefore 100= 2(n-1)\\

n - 1 = \frac{100}{2} \\

n - 1 = 50\\

n = 50 +1\\

\red{\bold{n = 51}}[/tex]

[tex]

\because S_n = \frac{n}{2}(a + a_n) \\\\

\therefore S_{51}= \frac{51}{2}(26 + 126) \\\\

\therefore S_{51}= \frac{51}{2}\times 152 \\\\

\therefore S_{51}= 51\times 76 \\\\

C) Sixty-seven times a number, plus eight and nine tenths, is not less than three hundred two.

D) Sixty-seven times a number, plus eight and nine tenths, is at least negative three hundred two.

the answer closest to this is B (not greater than is the same as less than or equal to)

Answer:

B)  Sixty-seven times a number, plus eight and nine tenths, is not greater than negative three hundred two.

Step-by-step explanation:

Let's break down this equation:

67z + 8.9 ≤ - 302

z is "a number" that is being multiplied by 67.

8.9 can be represented as 8 9/10, because 0.9 and a fraction is 9/10.

The less than or equal to sign means that the number represented by the expression 67z + 8.9 cannot be greater than -302. In other words, it is less than or equal to it.

You can see that option B is the only one that correctly compares 67z + 8.9 and -302. Therefore, that is the correct option.
