Answer: e. Função afim (Affine function)

Step-by-step explanation:

The question in english is a follows:

The function that is represented in a graph as a straight line is known as:

a.Exponential function

b. Quadratic function

c. Logarithmic function

d. Delta function

e. Affine function

So, the correct answer is option e, an affine function. Why?

Because an <u>affine function</u> is a polynomial function of the first degree that does not pass through the origin of coordinates in the cartesian plane, that is, through the point (0,0) when is graphed.

In fact an affine function is graphed as a straight line, because is a linear funcition in the form:

$f(x) = mx + n$

Where $m$ (the slope) and $n$ (the interception with y axis) are different from 0.

Find the slope of 8x-y=40

suter [353]

The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.

Find y:
8x-y=40
y = 8x - 40
slope = 8

Find the length of the third side. If necessary, write in simplest radical form

katrin [286]

HERE,

the $\huge{\triangle}$ is a right angle traingle.

length of one side= $\bold{ 1 }$

length of another side = $\bold{\sqrt{3} }$

so,

the length of third side=

$\bold{\sqrt{(1)^{2} +({\sqrt{3}})^{2}} }$

$\bold{\sqrt{1+3} }$

$\bold{\sqrt{4} }$

${\huge{\fcolorbox{aqua}{navy}{\fcolorbox{yellow}{blue}{\bf{\color{yellow}{2}}}}}}$

$\therefore$ ,the length third side of the traingle is 2.

A college-entrance exam is designed so that scores are normally distributed with a mean of 500 and a standard deviation of 100.

yawa3891 [41]

Answer:

The probability is 0.003

Step-by-step explanation:

We know that the average $\mu$ is:

$\mu=500$

The standard deviation $\sigma$ is:

$\sigma=100$

The Z-score is:

$Z=\frac{x-\mu}{\sigma}$

We seek to find

$P(x800)$

For P(x>800) The Z-score is:

$Z=\frac{x-\mu}{\sigma}$

$Z=\frac{800-500}{100}$

$Z=3$

The score of Z = 3 means that 800 is 3 standard deviations from the mean. Then by the rule of the 8 parts of the normal curve, the area that satisfies the conficion of 3 deviations from the mean has percentage of 0.15%

$P(x>800)=0.15\%$

For P(x<200) The Z-score is:

$Z=\frac{x-\mu}{\sigma}$

$Z=\frac{200-500}{100}$

$Z=-3$

The score of Z = -3 means that 200 is 3 standard deviations from the mean. Then by the rule of the 8 parts of the normal curve, the area that satisfies the conficion of 3 deviations from the mean has percentage of 0.15%

$P(x$

Therefore

$P(x800)=P(x800)$

$P(x800)=0.0015 + 0.0015$

$P(x800)=0.003$

a poker hand of 5 cards is dealt from a standard 52 card deck. a full house consists of exactly 3 of one kind of card and a pair

sergiy2304 [10]

The triple card can be any one of 13 values (ace through king). For each of those, the double card can be any one of the remaining 12 values. So concerning only the face values of the cards, there are (13 x 12) = 156 different full hice. If you include attention to the suits, then there a lot more.

Select ALL the sets of three sides that will make a triangle.

luda_lava [24]

9514 1404 393

Answer:

A. 2,3,4

D 3,4,5

Step-by-step explanation:

In order for segment lengths to be able to form a triangle, the sum of the shortest two must exceed the longest.

A. 2,3,4 . . . 2 + 3 > 4 . . . can make a triangle

B. 2,3,5 . . . 2 + 3 = 5 . . . not a triangle

C. 2,3,6 . . . 2 + 3 < 6 . . . not a triangle

D 3,4,5 . . . 3 + 4 > b . . . can make a (right) triangle

E. 3,4,8 . . . 3 + 4 < 8 . . . not a triangle
