At this rate how tall will the plant be 40 days after planting?

1 answer:

8 0

We are going to want to put this into slope-intercept formula. But first we need to find the slope

(5, 3) (25, 19)
(19-3)/(25-5)
16/20
4/5 = m

We then put this into the formula. But now we have to find b by plugging in one of the points as x and y.
y = 4/5x + b (10,7)
7 = 4/5(10) + b
7 = 8 + b
-1 = b
Our equation will be y = 4/5x -1.

Then we can plug in 40 as x to find the plant's height

y= 4/5(40) - 1
y= 32 - 1
y = 31 inches

Finally, the plant is 31 inches at 40 days.

The left side of a solid block is held at a constant temperature of 200°C. The temperature profile within the block is given by

Nikitich [7]

Answer:

with T = 50⁰C, we have:

50 = 200 - 5x - x²

<=> x² + 5x = 150

<=> x² + 5x - 150 = 0

=> x = 10

Help!!!!!!!!!!!!!!!!!!!!!!

zhuklara [117]

Answer:

see below

Step-by-step explanation:

9 ^-5 * 9^-3

When multiplying these we ADD the exponents:

9^-5 * 9^-3

= 9^(-5 + -3)

= 9 ^-8

= 1/9^8 Option A

2. 2^14 / 2^7 This is a division so we SUBTRACT the exponents:-

= 2^(14 - 7)

= 2^7 (answer)

3. If the triangle is a right angled one then it will obey Pythagoras Theorem so:-

13^ = x^2 + 5&2

x^2 = 13^2 - 5^2

x^2 = 144

x = 12 (answer)

4. The last choice is a crucial step.

The total area of the triangles is the same in both large squares so the area of the large square e^2 = a^2 + b^2 ( the 2 squares in the left side large square).

When is the best time to use square roots to solve a quadratic? Choose the one BEST

blondinia [14]

Answer: D, When the constants are perfect squares.

Step-by-step explanation:

the “best” method whenever the quadratic equation only contains x2 terms. That implies no presence of any x term being raised to the first power somewhere in the equation.

Hopefully this helps!
