Answer:

  b)  -9.8t +18

Step-by-step explanation:

b) The instantaneous rate of change is the derivative of the height function. The power rule is separately applied to each term, and the results added.

  power rule: d/dx(x^n) = nx^(n-1)

Then the derivative is ...

  dh/dt = 2(-4.9t^1) +18(1 ·t^0)

  dh/dt = -9.8t +18

__

If you haven't been introduced to derivatives as such, then you find the instantaneous rate of change by finding the average rate of change over a vanishing interval.

  [tex]\dfrac{dh}{dt}=\displaystyle\lim\limits_{h\to 0}{ \dfrac{h(t+h)-h(t)}{h}}\\\\\dfrac{dh}{dt}=\lim\limits_{h\to 0}\dfrac{(-4.9(t+h)^2+18(t+h)+23)-(-4.9t^2+18t+23)}{h}\\\\\dfrac{dh}{dt}=\lim\limits_{h\to 0}\dfrac{-4.9(2th+h^2)+18h}{h}=\lim\limits_{h\to 0}{(-9.8t +18 -4.9h)}\\\\ \boxed{\dfrac{dh}{dt}=-9.8t +18}[/tex]

i think itss this 45 45 90 triangle ratio

In a 45 45 90 triangle, the ratios are equal to: 1 : 1 : 2 for angles (45° : 45° : 90°) 1 : 1 : √2 for sides (a : a : a√2)Jun 26, 2020

Over here, we have a 45-45-90 special right triangle.

According to base angle theorem converse, this triangle is a congruent triangle so x = 14.

In a 45-45-90 triangle, the hypotenuse is the leg multiplied by [tex]\sqrt{2}[/tex]

So it would be:

14[tex]\sqrt{2\\}[/tex]

Hope this helps, let me know if you have any questions since it wasn't the best explanation.

Answer:

  26.13 ft²

Step-by-step explanation:

The total area is twice the area of the right triangles plus half the area of a circle of radius 3 ft.

  Semicircle area = (1/2)(πr²)

  semicircle area = (1/2)(3.14)(3 ft)² = 14.13 ft²

The area of the two right triangles is ...

  total triangular area = (3 ft)(4 ft) = 12 ft²

Then the area of the figure is ...

  figure area = semicircle area + total triangular area

  = 14.13 ft² + 12 ft² = 26.13 ft²

MN/sin72=10/sin18

MN=30.8

Answer:

21

Step-by-step explanation:

so if the ratio is 3:4

then we can also write the ratio as 3x:4x

where the total is 7x marbles and we see we have to chose the one that is divisible by 7 which is 21.

Answer:

The blue triangle -- ∆QRS only

Step-by-step explanation:

They have the same angles (49° and 96°) and the third angle would be 35°. The pink triangle has none of the same angles measurements

Activity 3.

Convert the following to the indicated measurement:

1. 86 km = 8600 dam

9. 6, 600 min = 110 htlrs

10. 415° F = 212.778° c

2. 2 mi = 126720 in

3. 20 in = 50.8 cm

11. 130 °C = 266° F

4. 25.1 gal = 100.4 qt

12. 2.3 gallon = 9.2 qt

5. 45 acre = 0.174 square km

13. 632 ft = 4.937 cords

6. 67.33 qt = 16.832 gallons

14. 5.1 lb = 35700 grains

7. 90.67 km = 9067 hectares

15. 1,800 oz = 51.029 kilograms

8. 6 days = 144 hours = 8640 minutes

Answer:

x = 5.01%

y = 11.1

Step-by-step explanation:

[tex]\frac{percent}{base} = \frac{rate}{100}[/tex]

Model:

50% of 120 is 60

   Rate (%) = 50

   Base (of) = 120

   Percent (is, part) = 60

Thus, x in the first problem is the rate.

[tex]\frac{3.006}{60} =\frac{x}{100}[/tex]. Cross multiply, and we get:

x = 5.01

To check, multiply 5.01% × 60 = 3.006

For the second problem, multiply 10% with 111 to get the percent, which is 11.1

Answer:

Step-by-step explanation:

find the lcm between 6 and 4

Answer:

He will wear both on the 12th day.

Step-by-step explanation:

Find the LCM (Least Common Multiple) of 4 and 6.

Prime factor both numbers:

4 =  2²

6 = 2 · 3

LCM = 2² · 3

       = 12

To find the LCM, take the greatest common numbers (2² and 3) and multiply them.

This method works well with very big numbers.
