Answer:

(2, 11)

Step-by-step explanation:

So, we have to make them equal to each other.

5 = 2x + 16

Subtract 5 from both sides

y = 2x + 11

Answer:

The second:   \bold{f (x) =4(x+\frac34)^2-\frac{21}4}

Step-by-step explanation:

                            f (x) =4x^2+6x-3\\\\f (x) =4(x^2+\frac64x]-3\\\\f (x) =4[x^2+2\cdot x\cdot\frac34+(\frac34)^2-(\frac34)^2]-3\\\\f (x) =4[(x+\frac34)^2-(\frac34)^2]-3\\\\f (x) =4(x+\frac34)^2-4(\frac34)^2-3\\\\f (x) =4(x+\frac34)^2-\frac94-\frac{12}4\\\\\underline{f (x) =4(x+\frac34)^2-\frac{21}4}

If a triangle has sides of 8,11, and 13. Is it a right triangle?
Vera_Pavlovna [14]

If a² + b² = c², then the triangle is <u>right</u>.

So we have (8)² + (11)²  <u>?</u>  (13)²

(8)² is 64, (11)² is 121, and (13)² is 169.

So we have 64 + 121 <u>?</u> 169

64 + 121 is 185 and we can see that 185 > 169.

This triangle would not be a right triangle.

In fact, it would be an acute triangle.

So no, it's not a right triangle.

A meteorologist who sampled 4 thunderstorms found that the average speed at which they traveled across a certain state was 16 mi
DENIUS [597]

Answer:

The  90 % confidence  interval  for the mean population is (11.176  ; 20.824 )

Rounding to at least two decimal places would give 11.18 , 20.83

Step-by-step explanation:

Mean = x`= 16 miles per hour

standard deviation =s= 4.1 miles per hour

n= 4

\frac{s}{\sqrt n}  =  4.1/√4= 4.1/2= 2.05

1-α= 0.9

degrees of freedom =n-1=  df= 3

∈ ( estimator  t with 90 % and df= 3 from t - table ) 2.353

Using Students' t - test

x`±∈ * \frac{s}{\sqrt n}

Putting values

16 ± 2.353 * 2.05

= 16 + 4.82365

20.824  ;        11.176

The  90 % confidence  interval  for the mean population is (11.176  ; 20.824 )

Rounding to at least two decimal places would give 11.18 , 20.83
