If f(x) = 3^x + 10 and g(x) = 2x − 4, find (ƒ+g)(x)

galina1969 [7]

Answer:

3^x+12x-4

Step-by-step explanation:

(f+g)(x) = f(x) + g(x) = 3^x + 10x + 2x - 4 = 3^x + 12x - 4

(1) 4p²q : 10pq²

tiny-mole [99]

Answer: (1) 2p: 5q.

(2) 3:10.

(3) 5:6.

Step-by-step explanation:

To find : Ratio

(1) 4p²q : 10pq²

$=\dfrac{4p^2q}{10pq^2}\\\\=\dfrac{2p^{2-1}}{5q^{2-1}}\\\\=\dfrac{2p}{5q}$

i.e. Simplified ratio of 4p²q : 10pq² is 2p: 5q.

(2) 9 months : 2½ years

1 year = 12 months

$2\dfrac{1}{2}\text{years}=\dfrac{5}{2}\text{years}\\\\=\dfrac{5}{2}\times12=30\text{ months}$

Now, 9 months : 2½ years = $\dfrac{9\text{ months}}{30\text{ months}}=\dfrac{3}{10}$

Hence, Simplified ratio of 9 months : 2½ years is 3:10.

(3) 5 m : 600 cm

1 m = 100 cm

So, 5m = 500 cm

Now, 5 m : 600 cm = $\dfrac{500\ cm}{600\ cm}=\dfrac{5}{6}$

Hence, Simplified ratio of 5 m : 600 cm is 5:6.

If you were filling the cylinder up with water using a cone that has the same height and diameter, how many cones will it take t

aleksandrvk [35]

Answer:

It required 3 cones to fill up the cylinder with the same height and diameter.

Step-by-step explanation:

Let the radius of the cone and cylinder be r.

Let the height of the cone and cylinder be h.

As we know that $\text{Volume of cylinder}=\pi r^2h$ ....(1)

$\text{Volume of cone}=\frac{1}{3}\pi r^2h$

It can be observed that the volume of a cone is $\frac{1}{3}$ rd the volume of the cylinder. so, multiply the volume of the cone by 3.

$3 \times \text{Volume of cone}=3 \times \frac{1}{3}\pi r^2h$

$3 \times \text{Volume of cone}= \pi r^2h$

$3 \times \text{Volume of cone}= \text{Volume of cylinder}$ (From equation 1 )

Hence, It required 3 cones to fill up the cylinder with the same height and diameter.
