What is the next term of AP : √2, √8, √18, .......?

solmaris [256]

Answer:

$\sqrt {32}$

Step-by-step explanation:

Next term of the given AP can be obtained by adding common difference (d) in the last term $\sqrt {18}$

$d = \sqrt{18} - \sqrt{8} = 3 \sqrt{2} - 2 \sqrt{2} = \sqrt{2} \\ next \: term = \sqrt{18} + \sqrt{2} \\ = 3 \sqrt{2} + \sqrt{2} \\ = 4 \sqrt{2} \\ = \sqrt{ {4}^{2} \times 2 } \\ = \sqrt{16 \times 2} \\ \huge \red{ \boxed{next \: term = \sqrt{32} }}$

Two different sized triangles have a scale factor of 2:3. If the hypotenuse ( the longest side ) of the bigger triangle measures

OlgaM077 [116]

Answer:

16 in

Step-by-step explanation:

The 3 part of the ratio represents 24 inches.

Dividing by 3 gives the value of one part of the ratio.

24 in ÷ 3 = 8 in ← value of 1 part of the ratio, thus

2 parts = 2 × 8 in = 16 in ← hypotenuse of smaller triangle

Please help meee, this is my homework . (Geometry) ... I’ll rate brainliest

Rama09 [41]

1. Volume of the sphere

$V = \frac 4 3 \pi r^3 = \frac 4 3 \pi ( 8^ 3) = \dfrac{2048 \pi}{3} \approx 
2144.66$

Choice c

2. Algebra making a token effort to pretend to be geometry. Complementary angles add to 90 degrees.

(x+1) + (x-3)=90

2x -2 = 90

2x = 92

x = 46

Angles x+1=47 and x-3=43

Choice b

3. midpoint A=-5, E=5

The midpoint is just the average of A and E, here zero, point D

choice b

4. I can't really tell if x is supposed to be an angle or a length in this figure; presumably a length. I suppose we're to assume parallel lines; so this makes similar shapes, i.e. a proportionality:

$\dfrac{24}{x} = \dfrac{36}{12} =3$

$x = \dfrac{24}{3} = 8$

Choice a

What is the volume of a sphere with a radius of 7 cm? Sphere V = 4 3 πr3 1. Substitute the radius into the formula: V = 4 3 π

netineya [11]

Answer:

1436.75504 or 1372/3π cm^3

Step-by-step explanation:

The volume of a sphere can be found using:

V = 4/3 πr^3

We know the radius is 7, so we can substitute 7 in for r

V = 4/3 π7^3

Evaluate the exponent

V = 4/3 π 343

If we want the answer in terms of pi, multiply the two other numbers, that are not pi: 4/3 and 343.

v= (4/3*343)π

v=1372/3π

If we want an exact answer, multiply 1372/3 and pi

v=1436.75504

So, the volume is 1436.75504 or 1372/3 π cm^3
