Answer:

D. 7.2

Step-by-step explanation:

6^2 +4^2 = c^2

sqrt 36 + sqrt 16 = c^2

c^2 = sqrt 52  =  7.21110255 = 7.2

Answer:

Step-by-step explanation:

Step-by-step explanation:

Distance between two points is given by

|xy|=√(x2-x1)² +(y2-y1)²

So putting the points A(-3,4) B(1,-2) into the equation

|AB|= √(4--3)²+(-2-1)²

=√(7)²+(-3)²

= √49+9

= √58

=7.2

Answer:

length = 31 ft

width = 19ft

largest perimeter = 100 ft

Step-by-step explanation:

Let’s say the variable is x, if you draw a rectangle, you’d lable the length as 12+x (because the length is 12 ft longer than the width) and you’d lable the width as x.

Then you’d multply both terms by 2 (and add them up):

2(12+x) + 2(x)

Once you distribute and add...

24 + 2x + 2x

24 + 4x

Then you’d set that equal to 100, since that’s the amount of fencing Dan has:

24 + 4x = 100

Subtract 24 on both sides:

4x = 76

Divide by 4 on both sides:

x = 19

Then you found the width, now to find the length, just add x to 12 (which equals to 31).

Add all the sides up and it equals to 100, which is the largest perimeter than can be created using 100 ft of fencing.

Hope this helped :)

I think Less then 1 or < 1 because that is what the graph is showing!

Step-by-step explanation:

It is point to the left which mean less then(<). If it were pointing to the right it would be greater than(>). And since the dot is at one, it’s 1.

Answer:

Active transport requires energy for the movement of molecules whereas passive transport does not require energy for the movement of molecules. In active transport, the molecules move against the concentration gradient whereas in passive transport, the molecules move along the concentration gradient.c

Answer:

144 ft^2

Step-by-step explanation:

We can split this shape into a rectangle and into a trapezoid. The rectangle we can use is the one with side lengths of 12.4 and 6, and to find this area we just multiply these two to get 74.4.

The trapezoid we can make has bases of 5 and 12.4, and has a height of 8 ft. The equation representing the height of a trapezoid is [tex]\\\frac{1}{2} (b_{1}+b_{2} )*h[/tex], and plugging in to this equation we get:

1/2(5+12.4)*8

1/2(17.4)*8

8.7*8

69.6

Finally, we add the area of the trapezoid and rectangle together to get 69.6+74.4=144

Discriminant and the number of real roots for this equation are 0, one real root.

Discriminant of a polynomial in math is a function of the coefficients of the polynomial.

The discriminant of a quadratic equation ax2 + bx + c = 0 is in terms of its coefficients a, b, and c. i.e.,

Discriminant = [tex]\sqrt{b^{2} -4ac}[/tex]

Given equation

[tex]4x^{2} +12x+9 = 0[/tex]

Discriminant = [tex]\sqrt{b^{2} -4ac}[/tex]

= [tex]\sqrt{12^{2}-4(4)(9) }[/tex]

= [tex]\sqrt{144-144}[/tex]

D = 0

Therefore, number of real roots is one.

Hence, discriminant and the number of real roots for this equation are 0, one real root.

Answer:320ft^2

Step-by-step explanation:

80% of 20 is 16, because 80% is 4/5 and 20 divided by 5 is 4, multiplied by 4 is 16. Area is L x W, so 16 times 20 is 320, and don't forget unit of measurement, ft^2 for area
