1 answer:
crimeas [40]3 years ago
5 0

Answer:

B

Step-by-step explanation:

4x + 11y = 3

11y = -4x + 3

y = -4/11x + 3/11

perp. 11/4

y - 7 = 11/4(x - 2)

y - 7 = 11/4x - 11/2

y -14/2= 11/4x - 11/2

y = 11/4x + 3/2

Find the linear approximation of f(x)=lnx at x=1 and use it to estimate ln(1.38).
RideAnS [48]
\bf f(x)=y=ln(x)\qquad &#10;\begin{cases}&#10;x=1\\&#10;y=ln(1)\to y=0&#10;\end{cases}\\\\&#10;-----------------------------\\\\&#10;\left. \cfrac{dy}{dx}=\cfrac{1}{x} \right|_{x=1}\implies 1\impliedby m&#10;\\\\\\&#10;\textit{now, we know that }&#10;\begin{cases}&#10;x=1\\&#10;y=0\\&#10;m=1&#10;\end{cases}\implies y-0=1(x-1)\implies y=x-1

now, you're asked to use it when ln(1.38), which is just another way of saying x = 1.38

so set x = 1.38 and see what "y" is

Please help me w the answer
evablogger [386]

Answer:

\frac{2(x-6)(x-10)}{(x-4)(x-5)}

Step-by-step explanation:

In essence, one needs to work their way backwards to solve this problem. Use the information to construct the function.

The function has verticle asymptotes at (x = 4) and (x = 5). This means that the denominator must have (x - 4) and (x - 5) in it. This is because a verticle asymptote indicates that the function cannot have a value at these points, the function jumps at these points. This is because the denominator of a fraction cannot be (0), the values (x - 4) and (x - 5) ensure this. Since if (x) equals (4) or (5) in this situation, the denominator would be (0) because of the zero product property (this states that any number times zero equals zero). So far we have assembled the function as the following:

\frac{()}{(x-4)(x-5)}

The function has x-intercepts at (6, 0), and (0, 10). This means that the numerator must equal (0) when (x) is (6) or (10). Using similar logic that was applied to find the denominator, one can conclude that the numerator must be ((x - 6)(x-10)). Now one has this much of the function assembled

\frac{(x-6)(x-10)}{(x-4)(x-5)}

Finally one has to include the y-intercept of (0, 120). Currently, the y-intercept is (60). This is found by multiplying the constants together. (6 * 10) equals (60). One has to multiply this by (2) to get (120). Therefore, one must multiply the numerator by (2) in order to make the y-intercept (120). Thus the final function is the following:

\frac{2(x-6)(x-10)}{(x-4)(x-5)}

the vaal dam can store 2536 million m3 of water when full. However it was 65 4% full on the 30 January 2020 how many litres of w
PIT_PIT [208]

Answer:

Current water in dam = 1,676.202 million m³ (Approx.)

Step-by-step explanation:

Given:

Storage capacity of dam = 2,536 million m³

Current water level = 65.4%

Find:

Current water in dam

Computation:

Current water in dam = Storage capacity of dam x Current water level

Current water in dam = 2,563 x 65.4%

Current water in dam = 1,676.202 million m³ (Approx.)

Is the relationship a function? (Show work if possible)
MakcuM [25]

Answer: No! This is not a function!

Step-by-step explanation:

Functions. Terms. Domain - The set of all inputs of a relation or function. Function - A relation in which each input has only one output. Often denoted f (x). Horizontal Line Test - If every horizontal line you can draw passes through only 1 point, x is a function of y.
