Answer:
<h2>For 6 weeks, the height will be 15 inches</h2>
Step-by-step explanation:
Step one:
given data
the initial height of plant= 3inches
growth in inches per week =2inches per wee
Step two:
for x number of weeks, the height is expressed as
With the given growth function, we can estimate the height of the plant after any number of weeks, say x=6, that is 6 weeks, the height will be
substitute x=6 in the growth function
Use the formula or complete the square.
The zeroes of the quadratic can be real and rational; real and irrational; complex conjugates.
If the quadratic is ax²+bx+c, x=(-b+√b²-4ac)/2a.
If b² > 4ac the solutions are real. If b²-4ac is a perfect square, the solutions are real and rational; otherwise they’re real but irrational.
If b² < 4ac the solutions are complex.
Answer: 2w
Step-by-step explanation: if the garden is shaped like a square, then all the sides are equal,
length = breadth, and the Area of a square or rectangle is the length multiplied by the breadth
and to find the length and breadth, we find the square root of the area
The area is 4w2
We know that 4 is the perfect square of 2, making 2 the square root of 4
And w2 is the square of w
This is elementary algebra, a x a = a2
b x b = b2, w x w = w2
So adding both together, the square root of 4w2 = 2w
Answer:
y = 2x + 10
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2 , then
y = 2x + c ← is the partial equation
To find c substitute (- 4, 2 ) into the partial equation
2 = - 8 + c ⇒ c = 2 + 8 = 10
y = 2x + 10 ← equation of line
