Whats the volume the triangular prism?

Sauron [17]

Answer:

Step-by-step explanation:

B ----> Base Area

Base is triangle

base = b = 10 in

height = h = 6 in

Area of base B = $\frac{1}{2}bh$

$=\frac{1}{2}*10*6\\\\= 5* 6\\\\= 30 \ in^{2}$

B = 30 in²

H = 15 in

Volume of triangular prism = BH

= 30 * 15

= 450 in³

Find the 50th term sequence 5 , -2 , -9 , -16

Anni [7]

5 - 7 = - 2 ;
- 2 - 7 = - 9 ;
-9 - 7 = -16 ;
"common difference" d is - 7 ;
The n-th term of an arithmetic sequence is of the form <span>an = a1 + (n – 1)d ;
</span>a50 = 5 + 49 × ( - 7 ) = 5 - 343 = - 338;

Nastasia [14]

Answer:

Sample size is $n=423$

Step-by-step explanation:

Given that,

Margin of error $=4$ %

Confidence level $=90$ %

Suppose, sample proportion $=0.5$

i.e. $\hat{P}=0.5$

We know that,

Margin of error $=2^*\sqrt{\frac{\hat{p}(1-\hat{p})}{n} }$

∴ $1.64\sqrt{\frac{0.5(0.5)}{n} } \leq 4\%$

$\Rightarrow 1.64\sqrt{\frac{0.25}{n} } \leq 0.04$

$\Rightarrow \frac{0.5}{\sqrt{n} } \leq \frac{0.04}{1.64}$

$\Rightarrow \frac{0.5}{\sqrt{n} } \leq 0.0243$

$\Rightarrow \sqrt{n}\geq \frac{0.5}{0.0243}$

$\Rightarrow \sqrt{n}\geq 20.57$

squaring on both side,

∴ $n=423.1249$

Hence, the sample size is,

$n=423$

Hence, the correct option is $(b).$

What is the effect on the graph of the function f(x) =^8x when f(x) is replaced with f(x − 2)?

docker41 [41]

Answer:

f(x - 2) = 8x - 16

Step-by-step explanation:

f(x) = 8x

f(x - 2) = 8(x - 2)

f(x - 2) = 8x - 16
