Answer:

(x + 5) and (x -1)

Step-by-step explanation:

Given

The attached graph

Required

The [tex]factors[/tex] of the graph

The x [tex]values[/tex] are where the [tex]curve[/tex] [tex]touches[/tex] the x-axis

The first is at:

[tex]x = -5[/tex]

Add 5 to both sides

[tex]x +5= -5+5[/tex]

[tex]x +5= 0[/tex]

This implies that the first factor is: (x + 5)

The second is at:

[tex]x =1[/tex]

Subtract 1 from both sides

[tex]x - 1 = 1 - 1[/tex]

[tex]x - 1 = 0[/tex]

This implies that the other factor is: (x - 1)

Answer:

d is correct i think because (e^2)^1/2 is equal to e^2*1/2

By simplifying the given equation ([tex]$\sqrt{e}[/tex])² we get e. Therefore, the correct answer is option D. e.

The set of positive real numbers which exist greater than 0 (zero) exists as the non-negative real numbers. The statement can be written as,

R ≥ 0

Which signifies the real numbers exist either positive or zero. The set will contain numbers like {0,1, 2, 3, 4, 5,…}.

Given: ([tex]$\sqrt{e}[/tex])²

Let, [tex]$\sqrt{e} = e^{1/2[/tex]

(√e)² = [tex]$e^{(1/2*2)[/tex]

Simplifying the above equation, we get

= e¹

= e

Therefore, the correct answer is option D. e

Step-by-step explanation:

Total amount of cookies = 4250

butter cookies, b

Almond cookies, a

Chocolate cookies, c

It made 715 more butter cookies than

almond cookies

b = a + 715

It made 5 times as many chocolate cookies as almond

5a = c

Total amount of cookies

= a + b + c

= a + (a+715) + (5a)

= 7a + 715

7a + 715 = 4250

7a = 4250-715

a = 3535 / 7

a = 505

c = 5a

= 5 (505)

= 2525

The factory make 2525 chocolate cookies.

The number of chocolate cookies made by the factory is 2525 cookies

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total number of cookies = 4250 cookies

Let the number of almond cookies be = a

Let the number of butter cookies be = b

Let the number of chocolate cookies = c

So , the equation is

a + b + c = 4250   be equation (1)

Now ,

715 more butter cookies than almond cookies

Butter cookies b = 715 + a   be equation (2)

And , 5 times as many chocolate cookies as almond cookies

Chocolate cookies c = 5a   be equation (3)

So , substituting the values of a , b and c in equation (1) , we get

a + ( a + 715 ) + 5a = 4250

7a + 715 = 4250

Subtract 715 on both sides of the equation , we get

7a = 3535

Divide by 7 on both sides of the equation , we get

a = 505 cookies

Substitute the value of a in equation (2) , we get

b = 715 + a

b = 715 + 505

b = 1220 cookies

Substitute the value of a in equation (3) , we get

c = 5a

c = 505 x 5

c = 2525 cookies

Hence , number of chocolate cookies made by the factory is 2525 cookies

Answer:

Step-by-step explanation:

To find the time at which both balls are at the same height, set the equations equal to each other then solve for t.

h = -16t^2 + 56t

h = -16t^2 + 156t - 248

-16t^2 + 56t = -16t^2 + 156t - 248

You can cancel out the -16t^2's to get

56t = 156t - 248

=> 0 = 100t - 248

=> 248 = 100t

=> 2.48 = t

Using this time value, plug into either equation to find the height.

h = 16(2.48)^2 + 56(2.48)

Final answer:

h = 40.4736

Answer is A y=2sec(2x)

The function whose graph is given by A y=2sec(2x)

A graph contains data of which input maps to which output.

Analysis of this leads to the relations which were used to make it.

For example, if the graph of a function is rising upwards after a certain value of x, then the function having increasingly output for inputs greater than that value of x.

If the function crosses x axis at some point, then for polynomial functions, we have those as roots of the polynomial.

The function that we are given graphed has the point (0,2), this means whichever function f(x) it represents f(0) = 2.

Now, only the sec function has the property that;

y=2sec(2x)

Answer:

The square root function is the inverse of the squaring function just as subtraction is the inverse of addition. To undo squaring, we take the square root. In general terms, if a is a positive real number, then the square root of a is a number that, when multiplied by itself, gives a.

Area of complete triangle= 1/2 ×6 ×9 = 27 Sq Unit.

Area of rectangle inside triangle = 2× 5 = 10 sq unit.

area of the gray part of the triangle =Area of triangle - Area of rectangle = 27-10 = 17 Sq unit

Gray area = Big triangle area - white

rectangle area

Gray area = 1/2 × 6 × 9 - 2 × 5

Gray area = 3 × 9 - 10

Gray area = 27 - 10

Gray area = 17

Answer:

27KG

Step-by-step explanation:

Mouse- M , Cat - C, Dog - D

M + C = 10 ----- (1)

M + D = 20 -------(2)

C + D = 24 --------(3)

(1) - (2) => C - D = -10 ---- (4)

(3) + (4) => 2C = 14

                => C = 7

Substitute C in (1)  => M + 7 = 10

                            => M = 3

Substitute M in (2) => 3 + D = 20

                            => D = 17

Therefore C + M + D = 7 + 3 + 17 = 27KG

Answer:

Part A - No

Part B - 100 %

Step-by-step explanation:

Part A.

This is because, a fair chance requires that each member has the same probability of being picked.

Since there are 4 towns, a fair chance would be 1/4.That is, 1 out of every town.

Part B

The probability of at least 1 representative after 6 number draws is P(at least 1)  = 1 - P(none from Town 1)

P(none from town 1) = 0

P(at least 1)  = 1 - P(none from Town 1)

P(at least 1)  = 1 - 0 = 1

In percentage 1 × 100 % = 100 %
