Answer:

15d² + 7d - 4

Step-by-step explanation:

Distribute

(5d + 4)(3d -1)

5d (3d - 1) + 4(3d - 1)

Distribute

15d² - 5d + 4(3d- 1)

Distribute

15d² - 5d + 12d- 4

Simplify

15d² + 7d - 4

Answer:

length = 1696 m

breadth = 571 m

Step-by-step explanation:

perimeter = 4534 m

let breadth be b

so length = b + 1125 m

so

perimeter of rectangular garden = 2(l+b)

4534 m = 2(b+1125m+b) {substituting the value}

or, 4534 m = 2(2b+1125m)

or, 4534 m = 4b + 2250 m

or, 4534 m - 2250m = 4b

or, 2284m = 4b

or, b = 2284m/4

so, b  = 571m

so, l = b + 1125 m

= 571 m + 1125m

= 1696 m

Answer: It is Exponential

Step-by-step explanation: There is a graph provided below.

The kind of model which describes the given data best is exponential.

An exponential graph is a curve that has a horizontal asymptote and it either has an increasing slope or a decreasing slope. i.e., it starts as a horizontal line and then it first increases/decreases slowly and then the growth/decay becomes rapid. It always cuts the y-axis at some point but it may or may not cut the x-axis. i.e., an exponential graph always has a y-intercept but it may or may not have the x-intercept.

According to the given question.

We have a data set {(-1, 0.5), (0,1), (1, 2), (3, 8), (5, 52)}.

So, if we locate this points on the graph.

We see that, when 'x' varies 'y' varies as [tex]2^{x}[/tex].

Hence, the kind of model which describes the given data best is exponential.

Thus, option B is correct.

Answer:

d < 100

Step-by-step explanation:

the distance is less than (<) 100 ft

d < 100

The sentence translates to the inequality  d < 100

There's not much else to say about this problem. We just simply replace the "less than" wording with its corresponding symbol. We can think of the inequality sign as an alligator mouth that always wants to eat the larger value (so the open ended side is facing toward the larger value).

Answer:

[tex]\angle PRQ = 80[/tex]

Step-by-step explanation:

Given

[tex]\angle SPR = 145^o[/tex]

[tex]\angle POT = 115^o[/tex]

See attachment

Required

Find [tex]\angle PRO[/tex]

First, calculate [tex]\angle RPO[/tex]

[tex]\angle RPO + \angle SPR = 180[/tex] --- angle on a straight line

So, we have:

[tex]\angle RPO + 145 = 180[/tex]

Collect like terms

[tex]\angle RPO = 180 - 145[/tex]

[tex]\angle RPO = 35[/tex]

Next, calculate PQR

[tex]\angle POR + \angle POT = 180[/tex]

So, we have:

[tex]\angle POR + 115 = 180[/tex]

Collect like terms

[tex]\angle POR = 180-115[/tex]

[tex]\angle POR = 65[/tex]

So, PRO is calculated as:

[tex]\angle PRO + \angle POR + \angle RPO = 180[/tex] --- angles in a triangle

So, we have:

[tex]\angle PRO + 65 + 35= 180[/tex]

[tex]\angle PRO + 100= 180[/tex]

Collect like terms

[tex]\angle PRO = 180-100[/tex]

[tex]\angle PRO = 80[/tex]

The iso parts of isometric means same, and It is similar becuase rigid trtransformation and the metric parts means measure. Basically isometric means same measure. Rigid transformation preserve "same measures" like angles and side lengths.

Answer:

4

Step-by-step explanation:

Sum of interior angles in a triangle is 180,

41 + 26u + u + 31 = 180

26u + u + 41 + 31 = 180

27u + 72 = 180

27u = 180 - 72

27u = 108

u = 108 / 27

u = 4

Answer:

$1,890

Step-by-step explanation:

To find the amount, we use the compound interest formula here

we have this as;

A = P(1 + r/n)^nt

Where ;

P is the amount invested which is $1,800

r is the interest rate which is 3.3% annually (3.3/100 = 0.033)

n is the number of times yearly interest is compounded which is 1 time yearly

t is the number of years which is 1.5 years

substituting these values, we have

A = 1800( 1 + 0.033)^(1 * 1.5)

A = 1,890

There are 71 people who are female OR study French OR both.

To find the number of people who are female OR study French OR both, we need to add the numbers in the Female row (excluding the "Total" column) and the numbers in the French column (excluding the "Total" row), and then subtract the number of people who study both French and are female, as they were counted twice.

Number of people who are female = 43

Number of people who study French = 28

Number of people who study both French and are female = 16

Total = Number of people who are female + Number of people who study French - Number of people who study both French and are female

Total = 43 + 28 - 16

Total = 71

So, there are 71 people who are female OR study French OR both.

Answer:

La diferencia del tiempo total de carrera entre el jugador 1 y 2 es 0.0[tex]\overline 3[/tex] minutos

Step-by-step explanation:

Primera vuelta;

El tiempo de vuelta del jugador 1 = 2,32 minutos

El tiempo de vuelta del jugador 2 = 18 segundos más que el del jugador 1

Por lo tanto, el tiempo de vuelta del jugador 2 = (2,32 + 18/60) minutos = 2,62 minutos

Segunda vuelta

El tiempo de vuelta del jugador 1 = 2,52 minutos

El tiempo de vuelta del jugador 2 = 20 segundos menos que el del jugador 1

Por lo tanto, el tiempo de vuelta del jugador 2 = (2.52 - 20/60) minutos = 2.18[tex]\overline 6[/tex] minutos

Tercera vuelta

El tiempo de vuelta del jugador 1 = 2,18 minutos

El tiempo de vuelta del jugador 2 = 2,18 minutos

El tiempo de vuelta total del jugador 1 = (2,32 + 2,52 + 2,18) minutos = 7,02 minutos

El tiempo de vuelta total del jugador 2 = (2,62 + 164/75 + 2,18) minutos = 524/75 minutos = 6.98[tex]\overline 6[/tex] minutos

La diferencia del tiempo total de carrera = (7.02 - 524/75) minutos = (1/30) minutos = 0.0[tex]\overline 3[/tex] minutos

Answer:

P + Q = 1

Step-by-step explanation:

Given: [tex]\frac{1+\sqrt{3} }{1-\sqrt{3} }[/tex]  = P - [tex]\sqrt{Q}[/tex]

This is a question on surd, so we need to rationalize the denominator to have;

[tex]\frac{1+\sqrt{3} }{1-\sqrt{3} }[/tex]  * [tex]\frac{1+\sqrt{3} }{1+\sqrt{3} }[/tex] = [tex]\frac{1+\sqrt{3}+\sqrt{3} + 3}{1+\sqrt{3}-\sqrt{3} -3 }[/tex]

   = [tex]\frac{4+ 2\sqrt{3} }{1-3}[/tex]

   = [tex]\frac{4+2\sqrt{3} }{-2}[/tex]

   = -2 - [tex]\sqrt{3}[/tex]

Thus,

-2 - [tex]\sqrt{3}[/tex] = P - [tex]\sqrt{Q}[/tex]

⇒ P = -2 and Q = 3

Therefore, the value of P + Q = -2 + 3

                                                 = 1

Thus,

P + Q = 1

Answer:

y=-(x+3)(x+1)(x-2)=-x^3-2x^2+5x+6

Step-by-step explanation:

If the zeros are:

x1=-3

x2=-1

x3=2

then the function is:

y = a (x-x1) (x-x2) (x-x3) = a (x+3) (x+1) (x-2)

y = a (x^3+2x^2-5x-6)

To find the value for "a" we use the information that, if x=1, then y=8:

y = a (1+2-5-6) = a (-8) = 8 therefore a=-1

So:

y=-(x+3)(x+1)(x-2)=-x^3-2x^2+5x+6
