sammy [17]3 years ago
6 0

Answer:

Step-by-step explanation:

If you'd graph this function on a graphing calculator or graphing utility, you'd see quickly that the graph never touches or crosses the x-axis.  This tells us immediately that there are no real roots; all four roots are complex or imaginary.

Theoretically, if a month is chosen 300 times,
horsena [70]

Answer:

75 times.

Step-by-step explanation:

Well there are 12 months and 3 of them start with the letter J, so theoretically, 25% of the months chosen will start with the letter J because \frac{3}{12}=\frac{1}{4}, which is 25%. 25% of 300 (or \frac{300}{4}, for those who like fractions) is 75, so theoretically, we can expect a month that starts with the letter J 75 times.

Hope this helps!

The formula to find the perimeter of a rectangle is: P = 2W + 2L. To solve for " W " in this formula, which steps should be foll
netineya [11]
Since the 2L is not being multiplied or divided, and it's positive, we will subtract it from both sides. Since the W is being multiplied by the 2, we'll also need to divide both sides by 2. 

Your answer is B.

A landscaper is designing a flower garden in the shape of a trapezoid. She wants the length of the shorter base to be 3 yards gr
gizmo_the_mogwai [7]
Correct Answer:
Option A. 17.1 Yards

Solution:
Let the height of trapezium is x yards. According to the given data, we can express the lengths of bases in terms of height.

The short base is 3 yards greater than the height, so measure of short base will be (x+3) yards.

The longer base is 5 yards greater than the height, so measure of longer base will be (x+5) yards.

Area of trapezium is given to be 360 square yards.

Area of trapezium = 0.5 x (Height) x (Sum of Bases)

Using the values, we get:

360=0.5(x)(x+3+x+5) \\  \\ &#10;720=x(2x+8) \\  \\ &#10;2 x^{2} +8x-720=0 \\  \\ &#10;2( x^{2} +4x-360)=0 \\  \\ &#10; x^{2} +4x-360=0 \\  \\ &#10;x= \frac{-4+- \sqrt{16-4(1)(-360)} }{2} \\  \\ &#10;x=  \frac{-4+- \sqrt{1456} }{2} \\  \\ &#10;x = 17.1 , -21.1

Since the height cannot have a negative value, we conclude that the height of trapezium rounded to nearest tenth of a yard will be 17.1 yards.
