each minute your heart pumps 1.5 gallons of blood around your body. How many pints of blood will your heart pump in a day? PLEASE HELP ME

Answers

Answer:

So there are 60 minutes in an hour, and since there are 24 hours in a day you will multiply 60 by 24:

60 * 24 = 1440.

That multiplied by 1.5 is 2160, so that would be your answer.

find the value c that will make 9x^2 +30x+c a perfect square trinomial

Answers

Answer:

[tex] c = 25[/tex]

Step-by-step explanation:

Given :-

A quadratic equation is given to us.The equation is 9x² + 30x + c .

And we need to find out the value of c for which the given trinomial is a perfect square. On looking at the given expression all the terms are having positive signs before them .So we can rewrite it on the basis of ,

Identity :-

[tex]\implies (a+b)^2=a^2+b^2+2ab[/tex]

Let's try to set the equation on this Identity .

The firsr term is 9x² . We can write it as ,

[tex]\implies 9x^2=(3x)^2[/tex]

Hence the middle term here should contain 3 and 2 as their factors. Let's Break the middle term .

[tex]\implies 30x = 2.3x.5 [/tex]

Therefore in order to make the whole expression as perfect square 5² must be replaced by c . The expression would become ,

[tex]\implies 9x^2+30x + 5^2 \\\\\implies (3x)^2+2.3x.5 +5^2\\\\\implies (3x+5)^2[/tex]

Hence the value of c should be 25 .

C = 25 you just multiply step by step exactly how it shows it on the problem/how u wrote it

jane used $68 more than two fifths of her last paycheck to purchase a new surfboard. If the surfboard cost $289, find the amount of her paycheck.

Answers

Answer: Let x be the amount of Jane's paycheck.

We know that:

surfboard cost = $289

and jane used $68 more than two fifths of her last paycheck to purchase a new surfboard.

So we can set an equation as:

surfboard cost = 2/5 x + $68

289 = 2/5 x + 68

Now we can substitute the known value in the above equation:

289 = 2/5 x + 68

221 = 2/5 x

x = (2215) / 2 = 115 = 55

So the amount of her paycheck is $55.

Therefore, jane's last paycheck was $55.

Convert the degree measure to radians or the radian measure to degrees. Then find one positive angle and one negative angle that is coterminal with the given angle.

1. -560°

2. 170°

Answers

-560° in radian is -28π/9 radian and the positive and negative coterminals are 8π/9 and -10π/9 respectively.

170° in radian is 17π/18 radian and the positive and negative coterminals are 53π/18 and -19π/18 respectively

How to convert the degree measure of angle to radians?

An angle can be converted from degree to radian by multiplying it by π/180.

1. -560°

-560° × π/180 = -28π/9 radian

2. 170°

170° × π/180 = 17π/18 radian

In general, if θ is any angle in radian, then θ + n(2π) is coterminal angle with θ, for all nonzero integer n.

coterminal of -28π/9:

positive: -28π/9 = -28π/9 + 2(2π) = 8π/9

negative: -28π/9 = -28π/9 + 2π = -10π/9

coterminal of 17π/18:

positive: 17π/18 = 17π/18 + 2π = 53π/18

negative: 17π/18 = 17π/18 - 2π = -19π/18

Find the area of the shaded region.
40 ft
16 ft
14 ft
10 ft

Answers

Answer:

Area = 780 ft²

Step-by-step explanation:

Area of the shaded region = area of rectangle A + area of rectangle B

Area of rectangle A = L*W

L = 40 ft

W = 16 ft

Area of rectangle A = 40*16 = 640 ft²

Area of rectangle B = L*W

L = 10 ft

W = 14 ft

Area of rectangle B = 10*14 = 140 ft²

Area of the shaded region = 640 + 140 = 780 ft²

The required function is [tex]f(x)=-2x^2+2[/tex]. Hence, option a is correct.

Important information:

The graph of a function passes through the points (0,2), (1,0) and (-1,0).Quadratic function:

The graph has two x-intercepts (1,0) and (-1,0). It means it is a quadratic function and [tex](x-1)[/tex] and [tex](x+1)[/tex] are two factors.

[tex]f(x)=a(x-1)(x+1)[/tex]

[tex]f(x)=a(x^2-1)[/tex] ...(i)

The graph passes through the point (0,2). Substitute [tex]x=0,f(x)=2[/tex] in the above function.

[tex]2=a(0^2-1)[/tex]

[tex]2=-a[/tex]

[tex]-2=a[/tex]

Substitute [tex]a=-2[/tex] in (i).

The perimeter of rectangle living room is 40 m the living room is 10 m wide what is the length of the living room

Answers

Answer:

Width of the room = 5 meters

Step-by-step explanation:

the rectangular living room is calculated as length * width

The area is given to be equal to 40 sq. meters (area = 40 sq. meters)

Let the width = x meters

Length = X+3 meters

Area = Length * Width

40 = X * (X+3)

40 = X^2 + 3X

We solve this quadratic equation

So x = 5 or x= -8

Width cannot be negative, so we reject x =-8

So x = 5 is the answer
