What is the output value for the following function if the input value is 3.2?

1 answer:

3 0

For functions, there is only many input values, but there can be only one output value, and there can be no identical x values. For this, x=3.2. If y= 2*3.2 - 1, then y=5.4.

I WILL GIVE BRAINLIEST!!! Part A: The Sun produces 3.9 ⋅ 10^33 ergs of radiant energy per second. How many ergs of radiant energ

Tems11 [23]

Answer:

Part A: This can be solved using cancellation of units: Energy produced (ergs) = (3.9 x 10^ 33 ergs/ sec)( 1.55 x 10^7 sec) = 6.045 x 10^40 ergs Part B: The grooves within a CD is very small, therefore it would be more reasonable to have a value of 1.6 x 10^-3 mm

Hope this helped you!

For what value(s) of x is the fraction 5x-10/x^2-25 undefined?

Korvikt [17]

The fraction will be undefined on x=5 and x=-5

Step-by-step explanation:

The fraction is undefined on values that make the denominator of the fraction zero.

Given fraction is:

$\frac{5x-10}{x^2-25}$

To find the values on which the denominator will be zero, we put the denominator equal to zero.

$x^2-25=0\\(x)^2-(5)^2=0\\(x+5)(x-5)=0\\x+5 = 0 => x=-5\\x-5 = 0 => x=5$

So,

The fraction will be undefined on x=5 and x=-5

Can y = sin(t2) be a solution on an interval containing t = 0 of an equation y + p(t) y + q(t) y = 0 with continuous coefficient

JulsSmile [24]

Answer:

Step-by-step explanation:

y = sin(t^2)

y' = 2tcos(t^2)

y'' = 2cos(t^2) - 4t^2sin(t^2)

so the equation become

2cos(t^2) - 4t^2sin(t^2) + p(t)(2tcos(t^2)) + q(t)sin(t^2) = 0

when t=0, above eqution is 2. That is, there does not exist the solution. so y can not be a solution on I containing t=0.

the equation of a parabola with a vertex at the origin is x2 = -4py. if 4p=16, what are the coordinates of the focus

egoroff_w [7]

Answer:

(0, -4)

Step-by-step explanation:

The given relations tell you ...

p = 16/4 = 4

Then the equation of the parabola is ...

x^2 = -16y

It opens downward, so the focus is below the vertex. The distance between the vertex and the focus is p = 4, so the focus is (0, -4).

The attached graph shows the parabola, along with its focus and directrix.

Answer:

38%

Step-by-step explanation:

Total: 93

Find percentage

Rain: 24

Snow: 11

24 + 11 = 35

Find what percentage of 90 35 is.

35 of 90 can be written as:

----

To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator by 100

35 100

---- × ----

90 100

= ( 35 * 100/90) * 1/100 = 38.89/100

Therefore, the answer is 38.89%
