What type of function maps an input onto itself?a. opposite function b. negative function c.identity function d. reflective function

Answers

Answer 1

Answer: A function which maps an input to itself, has the following formula:

f(x)=x.

The output is exactly equal to the input, for example:

f(5)=5, f(18)=18 .....

The function f(x)=x is called the "identity function"

Answer: C

7. $(f(4 + h) - f(4))/(h) = 8$
   $h((f(4 + h) - f(4))/(h)) = h(8) \nf(4 + h) - f(4) = 8h$
   $(h + 4)^(2) + (4)^(2) = 8h \n(h + 4)(h + 4) + 16 = 8h \nh(h + 4) + 4(h + 4) + 16 = 8h$
   $h(h) + h(4) + 4(h) + 4(4) + 16 = 8h \nh^(2) + 4h + 4h + 16 + 16 = 8h$
   $h^(2) + 8h + 32 = 8h \nh^(2) + 32 = 0$
   $h = \frac{-(0) \± \sqrt{(0)^(2) - 4(1)(32)}}{2(1)}$
   $h = \frac{0 \± \sqrt{(0)^(2) - 4(1)(32)}}{2}$
   $h = (0 \± √(-128))/(2)$
   $h = (0 \± 8i√(2))/(2)$
   $h =(8i√(2))/(2)$
   $h = 4i√(2)$

8. $f(x) = (x^(2) + 4x - 32)/(x - 4) \nf(x) = (x^(2) + 8x - 4x - 32)/(x - 4) \nf(x) = (x(x) + x(8) - 4(x) - 4(8))/(x - 4) \nf(x) = (x(x + 8) - 4(x + 8))/(x - 4) \nf(x) = ((x - 4)(x + 8))/(x - 4) \nf(x) = x + 8$

$g(x) = x(2x - 5) - 2(x^(2) - 3x - 4) \ng(x) = x(2x) - x(5) - 2(x^(2)) + 2(3x) + 2(4) \ng(x) = 2x^(2) - 5x - 2x^(2) + 6x + 8 \ng(x) = 2x^(2) - 2x^(2) - 5x + 6x + 8 \ng(x) = x + 8$

The functions are equivalent.

Amelia has a triangular kite with an area of 30 square inches and a height of 6 inches. How long is the base of the kite?

Answers

Area of triangle = 0.5 * base * height
30 = 0.5 * 6 * base
30 = 3 * base
so , base = 10 inch

Answer:

Draw a vertical line to break the kite into two equal triangles with a base of 36 and a height of 15. Use the formula A = 1

bh to find the area of each. The sum of the areas is the area of the kite.

Find an equation in standard form for the ellipse with the vertical major axis of length 6 and minor axis of length 4

Answers

Answer:

x^2/4 +y^2/9 = 1

Step-by-step explanation:

The standard form is ...

(x -h)^2/a^2 +(y -k)^2/b^2 = 1

for an ellipse centered at (h, k) with semi-axis measures "a" and "b". The largest of "a" or "b" is the semi-major axis; the smaller, the semi-minor axis.

Here, the major axis is vertical, so b > a.

Since the center is not given, we assume it is the origin: h = k = 0. The semi-axes are a=2, b=3, so the equation is ...

x^2/4 +y^2/9 = 1

Wich expression defines the given series for seven terms? 8+13+18+.......

Answers

Answer: a+6d will defines the series for seven terms i.e. 38.

Step-by-step explanation:

Since we have given that

$8+13+18+......$

Here, a = first term = 8

d = common difference is given by

$a_2-a_1\n\n=13-8\n\n=5$

So, we need to find the seven terms:

So, here n = 7

So, it becomes,

$a_7=a+(n-1)d\n\na_7=8+(7-1)5\n\na_7=8+6* 5\n\na_7=8+30\n\na_7=38$

Hence, a+6d will defines the series for seven terms i.e. 38.

you're just adding 5
example
8+5= 13
13+5=18
18+5=23
23+5=28
28+5=33
and so on :)

Josephine noticed that out of 10 e-mails she received, 7 were advertisements. What can she predict about the number of advertisements she will receive in the next 100 e-mails?

Answers

Josephine will receive approximately 70 advertisements in the next 100 e-mails she receives.

What is the probability?

The possibility of an event in time is known as probability in mathematics. How frequently does the incidence occur over the course of a specific time period, in plain English?

If Josephine received 7 advertisements out of 10 e-mails, then we can say that the probability of receiving an advertisement in a single e-mail is 7/10 or 0.7.

Assuming that the probability of receiving an advertisement in an e-mail remains the same for all e-mails, we can use this probability to make a prediction about the number of advertisements she will receive in the next 100 e-mails.

The expected number of advertisements in 100 e-mails can be calculated by multiplying the probability of receiving an advertisement in a single e-mail by the total number of e-mails:

Expected number of advertisements = probability of an advertisement x total number of e-mails

= 0.7 x 100

= 70

Therefore, based on the given information, we can predict that Josephine will receive approximately 70 advertisements in the next 100 e-mails she receives.

She can expect 70 to be ads since there is 10 times more emails so 7 times 10 is 70 so 70 ads
