Answer:

Option B) minimum value at −10

Step-by-step explanation:

we have

[tex]f(x)=x^{2} -10x+15[/tex]

This function represent a vertical parabola open upward (because the leading coefficient is positive)

The vertex represent a minimum

Group terms that contain the same variable, and move the constant to the opposite side of the equation

[tex]f(x)-15=x^{2} -10x[/tex]

Divide the coefficient of term x by 2

10/2=5

squared the term and add to the right side of equation

[tex]f(x)-15=(x^{2} -10x+5^2)[/tex]

Remember to balance the equation by adding the same constants to the other side

[tex]f(x)-15+5^2=(x^{2} -10x+5^2)[/tex]

[tex]f(x)+10=(x^{2} -10x+25)[/tex]

rewrite as perfect squares

[tex]f(x)+10=(x-5)^{2}[/tex]

[tex]f(x)=(x-5)^{2}-10[/tex] ----> function in vertex form

The vertex of the quadratic function is the point (5,-10)

therefore

The minimum value of the function is -10

Answer:

C. because you would multiply each of the 6 cars by the amount of people it can hold which is 6

Answer:

Step-by-step explanation:

The graph that will lie above the x-axis will be having only positive values throughout its domain,

So, We have to check which graph is having y > 0 for every x.

clearly y will be negative for many values of x , as coefficient of variable is negative.

Put x = 0, you will get y as negative .

Since, Square of anything will always be positive , and here constant term is also positive , so, It will always be positive .

Thus, it is having its graph always above x axis.

Put x = 0 , y = -7, which is negative

Answer:

Option C.

Step-by-step explanation:

The vertex form of a parabola is

[tex]y=a(x-h)^2+k[/tex]

where, a is constant, (h,k) is vertex.

If a<0, then it is a downward parabola and if a>0, then it is an upward parabola.  

A downward parabola never lies entirely above the x-axis.

First equation is

[tex]y=-(x+7)^2+7[/tex]

It is a downward parabola and vertex is (-7,7).

Second equation is

[tex]y=(x-7)^2-7[/tex]

It is an upward parabola and vertex is (7,-7).

Third equation is

[tex]y=(x-7)^2+7[/tex]

It is an upward parabola and vertex is (7,7).

Fourth equation is

[tex]y=(x-7)[/tex]

It is a linear equation with y-intercept -7.

Only equation 3 is an upward parabola whose vertex lies above the x-axis.

Hence the correct option is C.

Answer:

95 nickels 19 dimes

Step-by-step explanation:

d=dimes

5d=nickels

0.05(5d) + 0.10(d) = 6.65

0.25d + 0.10d = 6.65

0.35d=6.65

Divide by 0.35

d= 19 (19 coins)

19 dimes =$1.9

6.65-1.9= $4.75

Nickels=$4.75

4.75/0.05 = 95 coins

19*5=95

  114 coins in total

19*0.10 = 1.9

95*0.05=4.74

4.75+1.9= 6.65

Answer:

There are 19 dimes and 95 nickels

Step-by-step explanation:

Represent the numbers of nickels and dimes by n and d.  Then n = 5d.

The value of the nickels is $0.05n and that of the dimes is $0.10d.  Together these two amounts come to $6.65:

$0.05n + $0.10d = $6.65.

But n = 5d.

Substituting 5d for n, we get:

$0.05(5d) + $0.10d = $6.65

Combining the two terms on the left, we get:

0.25d + 0.10d = 6.65, or

0.35d = 6.65.

Solving for d, we get d = 6.65/0.35, or d = 19.  Since n = 5d, n = 5(19) = 95.

There are 19 dimes and 95 nickels.

The Answer is [tex]\frac{3657}{1000} \ or \ 3.657[/tex]

Step-by-step explanation:

Given

[tex]3\times1+\frac{6\times1}{10}+\frac{5\times1}{100}+\frac{7\times1}{1000}\\[/tex]

Now Solving Above using PEDMAS rule we get;

[tex]3+\frac{6}{10}+\frac{5}{100}+\frac{7}{1000}[/tex]

Now we will make take LCM we get;

[tex]\frac{3\times1000}{1000}+\frac{6\times100}{10\times100}+\frac{5\times10}{100\times10}+\frac{7\times1}{1000}\\\\\frac{3000}{1000}+\frac{600}{1000}+\frac{50}{1000}+\frac{7}{1000}\\\\\frac{3000+600+50+7}{1000}\\\\\frac{3657}{1000} \ or \ 3.657[/tex]

Hence the answer is  [tex]\frac{3657}{1000} \ or \ 3.657[/tex]

When y is 4, p is 0.5, and m is 2, x is 2. If x varies directly with the product of p and m and inversely with y, which equation models the situation?

xpmy=8

xy/pm=8

xpm/y=0.5

x/pmy=0.5

The equation models the situation is [tex]\frac{x y}{p m}=8[/tex]

Given that  

x is 2, y is 4, p is 0.5, and m is 2

x varies directly with the product of p and m

x varies inversely with y

[tex]\text {Product of } p \text { and } m=p \times m=p m[/tex]

x varies directly with the product of p and m

[tex]=>x \propto p m[/tex] ---- eqn 1

As x varies inversely with y,

[tex]=>x \propto \frac{1}{y}[/tex]   ----- eqn 2

From (1) and 2, we can say that

[tex]x \propto \frac{p m}{y}[/tex]

[tex]\Rightarrow x=k \frac{p m}{y}[/tex]

where k is constant of proportionality

[tex]\Rightarrow \frac{x y}{p m}=k[/tex]   ---- eqn 3

On substituting given values of x = 2, y = 4, p = 0.5 and m= 2 in eqn (3) we get

[tex]\frac{x y}{p m}=\frac{2 \times 4}{0.5 \times 2}=k[/tex]

[tex]\begin{array}{l}{\frac{x y}{p m}=\frac{8}{1}=k} \\\\ {=>\frac{x y}{p m}=8}\end{array}[/tex]

Hence correct option is second that is [tex]\frac{x y}{p m}=8[/tex]

Answer:

Step-by-step explanation:

Answer:

Part 1)  [tex]x^{2} -2x-2=(x-1-\sqrt{3})(x-1+\sqrt{3})[/tex]

Part 2)  [tex]x^{2} -6x+4=(x-3-\sqrt{5})(x-3+\sqrt{5})[/tex]

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

[tex]ax^{2} +bx+c=0[/tex]

is equal to

[tex]x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}[/tex]

Part 1)

in this problem we have

[tex]x^{2} -2x-2=0[/tex]

so

[tex]a=1\\b=-2\\c=-2[/tex]

substitute in the formula

[tex]x=\frac{-(-2)(+/-)\sqrt{-2^{2}-4(1)(-2)}} {2(1)}\\\\x=\frac{2(+/-)\sqrt{12}} {2}\\\\x=\frac{2(+/-)2\sqrt{3}} {2}\\\\x_1=\frac{2(+)2\sqrt{3}} {2}=1+\sqrt{3}\\\\x_2=\frac{2(-)2\sqrt{3}} {2}=1-\sqrt{3}[/tex]

therefore

[tex]x^{2} -2x-2=(x-(1+\sqrt{3}))(x-(1-\sqrt{3}))[/tex]

[tex]x^{2} -2x-2=(x-1-\sqrt{3})(x-1+\sqrt{3})[/tex]

Part 2)

in this problem we have

[tex]x^{2} -6x+4=0[/tex]

so

[tex]a=1\\b=-6\\c=4[/tex]

substitute in the formula

[tex]x=\frac{-(-6)(+/-)\sqrt{-6^{2}-4(1)(4)}} {2(1)}[/tex]

[tex]x=\frac{6(+/-)\sqrt{20}} {2}[/tex]

[tex]x=\frac{6(+/-)2\sqrt{5}} {2}[/tex]

[tex]x_1=\frac{6(+)2\sqrt{5}}{2}=3+\sqrt{5}[/tex]

[tex]x_2=\frac{6(-)2\sqrt{5}}{2}=3-\sqrt{5}[/tex]

therefore

[tex]x^{2} -6x+4=(x-(3+\sqrt{5}))(x-(3-\sqrt{5}))[/tex]

[tex]x^{2} -6x+4=(x-3-\sqrt{5})(x-3+\sqrt{5})[/tex]

LCM is 3 (x + 1)(x - 5)(x + 2)

Step-by-step explanation:

Given polynomials are:

x2 - 4x – 5 and x2 – 3x – 10.

Factorizing x^2-4x-5

[tex]x^2-4x-5\\= x^2-5x+x-5\\=x(x-5)+1(x-5)\\=(x+1)(x-5)[/tex]

Factorizing  x^2 – 3x – 10

[tex]x^2 -3x -10\\=x^2-5x+2x-10\\=x(x-5)+2(x-5)\\=(x+2)(x-5)[/tex]

Looking at the fators of both polynomials we can see:

The LCM will be the combination of all factors of polynomials. The factor that occurs in both factorization will be written only once

Hence,

LCM is 3 (x + 1)(x - 5)(x + 2)

Answer:

From fourth month onwards, the growth rate of [tex]f(x)[/tex] is greater than that of [tex]g(x)[/tex].

Step-by-step explanation:

Given:

The growth rates of both bank accounts are given as:

[tex]f(x)=3^x\\g(x)=5x+25[/tex]

Now, as per question, we need to find the value of 'x' when the value of [tex]f(x)>g(x)[/tex]. Or,

[tex]3^x>5x+25[/tex]

Now, we can do this by checking the values of 'x' by hit and trial method.

Let [tex]x=1[/tex]. The inequality becomes:

[tex]3^1>5(1)+25\\3>30(False)[/tex]

Let [tex]x=2[/tex]. The inequality becomes:

[tex]3^2>5(2)+25\\9>35(False)[/tex]

Let [tex]x=3[/tex]. The inequality becomes:

[tex]3^3>5(3)+25\\27>40(False)[/tex]

Let [tex]x=4[/tex]. The inequality becomes:

[tex]3^4>5(4)+25\\81>45(True)[/tex]

Therefore, the value of 'x' for which [tex]f(x)>g(x)[/tex] is 4.

So, from the fourth month onwards, the balance in [tex]f(x)[/tex] becomes greater than [tex]g(x)[/tex].

The graphical solution is shown below to support the same.

From the graph, we can conclude that after the 'x' value equals 3.4, the graph of [tex]f(x)[/tex] lies above of [tex]g(x)[/tex]. Hence, [tex]f(x)>g(x)[/tex] for [tex]x>3.4[/tex]

13 * 5 = 65

So, he needs 65 stickers

65/10 = 6.5

He will need 7 sheets, but will only use 6 and a half sheets.

Kyle will need to buy 7 sheets of stickers to have enough for all 13 of his notebooks, given that each notebook requires 5 stickers and each sheet contains 10 stickers.

Kyle needs a total of 65 stickers for his 13 notebooks, since he puts 5 stickers on each notebook. There are 10 stickers per sheet, so to find out how many sheets Kyle needs, we divide the total number of stickers by the number of stickers per sheet: 65 stickers ÷ 10 stickers/sheet = 6.5 sheets. Since Kyle cannot buy half of a sticker sheet, he will need to buy 7 sheets of stickers to have enough for all his notebooks.

Answer:

Rob is 76 cm tall.

Step-by-step explanation:

Let b = height of bill.

Let m = height of Mary.

Let r = height of Rob.

"the total heigh of bill mary and rob is 180 cm"

b + m + r = 180         Equation 1

"bob* is twice as tall as bill"

*I think you meant Rob is twice as tall as Bill.

r = 2b

"mary is 28 cm taller than bill"

m = b + 28

Substitue r = 2b and m = b + 28 into Equation 1.

b + b + 28 + 2b = 180

4b + 28 = 180

4b = 152

b = 38

r = 2b

r = 2(38) = 76

Rob is 76 cm tall.

Rob height is 76cm.

Given that,

According to the given data, computation of the data are as follows,

Let Bill height be X, then Rob height is 2X and Mary height is X + 28.

So, X + 2X + X + 28 = 180cm

4X = 180 - 28

X = 152 [tex]\div[/tex] 4

X = 38

Hence, Bill height = X = 38cm

Rob height = 2X = 76cm

Mary height = X + 28 = 66cm
