What are the roots of the quadratic equation X² + 4X + 4. How many roots are there.
kogti [31]
If we set the equation equal to 0, we can factor it to find its roots:

x² + 4x + 4 = 0
(x + 2)(x + 2) = 0
x = -2

This graph has one root, a double root, at -2.  This means that a single point, which must be the vertex of the parabola, touches the x-axis at (-2, 0)

Use the laplace transform to solve the given initial-value problem. y' + y = (t − 1), y(0) = 3
GaryK [48]

In mathematics, the Laplace transform, named after its discoverer Pierre Simon Laplace, transforms a function of real variables (usually in the time domain) into a function of complex variables (in the time domain). is the integral transform that Complex frequency domain, also called S-area or S-plane).

A line passes through the points (0, 9) and (9, 19). What is its equation in slope-intercept form?
STatiana [176]

Answer:

y = 10/9x + 9

Step-by-step explanation:

To write the equation in its slope-intercept form, y = mx + b, we need to find the slope (m) of the line and its y-intercept (b).

Given the points (0, 9) and (9, 19), we can solve for the slope of the line using the following formula:

m = \frac{y2 - y1}{x2 - x1}

Let (x1, y1) = (0, 9)

and (x2, y2) = (9, 19)

Substitute these values on the formula:

m = \frac{y2 - y1}{x2 - x1} = \frac{19 - 9}{9 - 0} = \frac{10}{9}

Therefore, the slope (<em>m </em>) = 10/9.

Next, the <u>y-intercept</u> is the point on the graph where it crosses the y-axis, and has the coordinates, (0, <em>b </em>). It is also the value of the y when x = 0.

One of the given points is the y-intercept of the line, given by (0, 9). The y-coordinate, 9, is the value of b.

Therefore, the linear equation in slope-intercept form is: y = 10/9x + 9

Sow your work plz and thank you! Best answer gets brainliest!
ELEN [110]
  • First of all, a 2 foot kangaroo is casting a 7 foot shadow.
  • Next we do 7 divided by 2 which equals 3.5.
  • Since we know the shadow is going to be 3.5x the object size we have to divide its shadow by 3.5
  • 14 divided by 3.5 is  4 so the Eucalyptus tree is 4ft long

<u><em>    Your answer=4ft </em></u>

<u><em></em></u>

Hope this helps!

the answer is 300

Step-by-step explanation

there are 16 people so we divide that by the total number of students

400 divided by 16 = 25

since there are 12 right handed in each group we multpily it by 12

25 x 12 = 300
