Given function is f(t)=0.4t

Let the number f days that have passed since the seed was planted = t

As mentioned, Julie measured and determined the height of plant after 30 days so initially the value of t = 30

But we have to find the value of f(t) at t = 10

so f(10) = 0.4*10

f(t) = 4

P = 215(1.005)t/3

Reil [10]

Answer:

(D) 36

Step-by-step explanation:

0.5% = 0.5/100 = 0.005

It is given that the population (215) is predicted to increase by 0.5%. To know the value after increment, 215 has to be multiplied by (1 + 0.005) or 1.005.

In the equation P = 215(1.005)t/3, the value of t/3 has to be equal to 1 for 0.5% increase.

t/3 = 1

t = 3 years

Convert years to months.

n = 3 ⋅ 12 months

n = 36 months

The correct option is D.

Thanks!

Write the equation of the line that passes through the points (8,−7) and (−9,7). Put your answer in fully reduced point-slope fo

Sunny_sXe [5.5K]

Answer:

y + 7 = (-14/17)(x - 8)

Step-by-step explanation:

We want the equation of this line in the point-slope form y - k = m(x - h).

We are given two points (8, -7) and (-9, 7), and may arbitrarily choose one of them to serve as the point (h, k) in the point-slope form shown above. Then the other point is represented by (x, y) in the point slope form shown above:

Let (h, k) be 8, -7) and let (x, y) be (-9, 7). Then, y - k = m(x - h) becomes:

7 - (-7) = m(-9 - 8), so that 14 = m(-17), and the slope is thus m = -14/17

The desired equation is then y + 7 = (-14/17)(x - 8) (which is in point-slope form).

Another way to get this result would be to find m in the usual way:

rise 14

m = ------------- = --------- = -14/17 (same as before).

run -17

Triangle MAT is isosceles, angle A is the vertex angle, AT = 8x-3, MT = 2x+3 and MA=5x+15. Find the value of x and the indicated

Anvisha [2.4K]

Answer:

x=6, AT=45, MT=15, MA=45

Step-by-step explanation:

Because it is isosceles, MA=AT, so 8x-3=5x+15, solve for x and then plug it into the equations.

Compose the trapezoid into a parallelogram what is the area of the trapezoid

Kay [80]

9514 1404 393

Answer:

26 square feet

Step-by-step explanation:

When two of the trapezoids are combined to make a parallelogram, the height remains the same (4 ft), but the width is the sum of the base lengths, 10 ft + 3 ft = 13 ft.

The area of the combined trapezoids is ...

A = bh = (13 ft)(4 ft) = 52 ft^2

The area of one trapezoid is half that, so is ...

A = (52 ft^2)/2 = 26 ft^2 . . . . area of the trapezoid
