Describe the transformation required to obtain the graph of the given function from the basic trigonometric graph.

Mathematics
1 answer:
Alik [6]3 years ago

Answer:

Option d

Step-by-step explanation:

If the graph of the function y=cf(x) +b  represents the transformations made to the graph of y= f(x)  then, by definition:

If  0 then the graph is compressed vertically by a factor c.

If  |c| > 1 then the graph is stretched vertically by a factor c.

If c  then the graph is reflected on the x axis.

If b> 0 the graph moves vertically upwards.

If b the graph moves vertically down

In this problem we have the function y=cscx -9 and our parent function is y = cscx

therefore it is true that c =1  and b =-9 < 0

Therefore the graph of y=cscx is not stretched vertically and is not reflected.  however as b then the graph moves vertically 9 units down. <u><em>Observe the image</em></u>

The answer is <em>"vertical translation down 9 units"</em>

How do you find the original price after a discount. The sales price is 55.50 and the percent of discount is 75%.
Arte-miy333 [17]
Well first we know that 55.50 is 25% so I guess multiply it by 3 to get the full price equalling nearly 166 which is closest to 165, so that’d be my answer. Sorry if wrong.

Sveta_85 [38]

Answer:

$ 3 left ashley money

$ 1 left  jacks money

$ 8 left ashley money

$ 4 left jacks money

Step-by-step explanation

3 pencils + 6 rulers = 12 - 9 = 3

5 pencils +  2 rulers = 8 - 7 = 1

12 - 4 = 8

8 - 4 = 4

The length of a rectangle is 24 units. Can the perimeter x of the rectangle be 60 units when its width y is 11 units? (1 point)
zlopas [31]
The first choice is correct. No, the rectangle cannot have x=60 and y=11 because x=48+2y.

Perimeter is x=2w+2y. Therefore x=2(24)+2(11) which equals 70 not 60.

How many and what type of solutions does 7x^2−4x+3 have? 1 rational solution 2 rational solutions 2 irrational solutions 2 nonre
Gre4nikov [31]

Answer:

2 non real solutions.

Step-by-step explanation:

We need to use discriminant,

for ax²+bx+c=0

The discriminat is b²-4ac

If the discriminant is,

→ less than 0, then 0 real solutions

→ equal to 0, then 1 real solutions

→ more than 0, then 2 real solutions

Given that,

7x²−4x+3=0

a=7, b=-4, and c=3

→ (-4)²-4(7)(3)

→ 16-84

→ -68

You can see this is less than 0, then non real solutions. [2 nonreal solutions]
