Answer:

x=14.4

Step-by-step explanation:

x= $\sqrt{h^2-a^2} \\$

x= $\sqrt{28^2-24^2}$

x= $\sqrt{784-576}$

x= $\sqrt{208}$

x=14.4

Answer:

The answer will be 14.4

Step-by-step explanation:

784-576 = x squared

= 208

the square root of 208 is

What is the explicit formula for this sequence? 2,10,50,250,1250

Valentin [98]

Answer:

$a_n = 2(5)^{n-1}$

Step-by-step explanation:

Explicit Geometric Formula: $a_n = a_1r^{n-1}$

a₁ is 1st term

r is common ratio

n is term number

Step 1: Find common ratio r

r = 10/2 = 5

Step 2: Plug variables into formula

$a_n = 2(5)^{n-1}$

The two-way frequency table below shows data on student behavior and the use of positive phone calls home as an incentive for go

dusya [7]

Answer:

From the frequency table, let's calculate the row total.

Row total for phone call = 19 + 9 = 28

Row total for no phone call = 8 +6 = 14

To calculate their respective row relative frequencies, let's use:

Row relative freq = $\frac{freq.}{Row total}$

Now, the two-way frequency table will be computed as:

For phone call:

Desirable behavior = $\frac{19}{28} = 0.67857$ ≈0.69

Undesirable behaviour = $\frac{9}{28} = 0.3214$ ≈0.32

No phone call:

Desirable behaviour = $\frac{8}{14} = 0.5714$ ≈ 0.57

Undesirable behaviour = $\frac{6}{14} = 0.4286$ ≈ 0.43

The complete two-way table is attached.

Help me on this please !!

zaharov [31]

Step-by-step explanation:

Hey, there !!

It's simple lets get started with simple solution,

Given the sequences are,

10,8,6,4....

Then,

common diifference= 2

now, we have formula,

$an = a1 + d(n - 1)$

$or \: an= 10 + 2(n - 1)$

$or \: an \: = 10 + 2n - 2$

$an \: = 2n + 8$

$or \: an = 2(n + 4)$

Therefore, The answer is an = 2( n+4) or, 10+2(n-1)...

{ note: 2(n+4) is simplified form of 10 +2(n-1).}

Hope it helps...
