Answer:

f(s(w)) = 80w+30

Step-by-step explanation:

Given

The function g(s) = 2s + 30 that represents the number of flowers that bloomed, where s is the number of seeds she planted.

The function s(w) = 40w represents the number of seeds she plants per week, where w represents the number of weeks.

Required

Composite function that represents how many flowers Lily can expect to bloom over a certain number of weeks.

The composite expression needed is g(s(w)

g(s(w)) = f(40w)

To get g(40w), we will replace s with 40w in g(s) as shown;

g(s) = 2s+30

g(40w) = 2(40w)+30

g(40w) = 80w+30

g(s(w)) = 80w+30

Hence the required composite function is expressed as g(s(w)) = 80w+30

Answer:

f(s(w)) = 80w+30

Step-by-step explanation:

Just wanted to confirm, the person who answered your question prior to mine is correct. I just took the exam on polynomial operations and graded, this was what I had written, and it is correct. W represents the weeks in f[s(w)], where its added to 80. s(w) tells the number of seeds per each week.

Find the domain and range of the function graphed in the picture.
algol [13]

The domain is the set of allowed x inputs, or x coordinates of a function. In this case, any point on the curve has an x coordinate that is 4 or smaller.

Therefore, the domain is the set of numbers x such that x \le 4

To write this in interval notation, we would write (-\infty, 4] This interval starts at negative infinity and stops at 4. We exclude infinity with the curved parenthesis and include 4 with the square bracket.

-----------------------------------------------------------------------

The range is the set of possible y outputs. Every point on this curve has a y coordinate that is either 0 or it is larger than 0.

The range is the set of y values such that y \ge 0

In interval notation, it would be written as [0, \infty) This time we start at 0 (including this endpoint) and "stop" at infinity

note: we always use curved parenthesis at positive or negative infinity because we cannot reach either infinity

Which sentence can represent the inequality x+251/1
wariber [46]

The sum of half of a number and three-fourths is at least five and one quarter.

It's all about making sense of an English statement. "half the sum" and "the sum of half" are two distinct expressions.

Additionally, "at least" and "not less than" have equivalent meanings, as do "not more than" and "at most."

It is an issue of matching the thoughts conveyed because all of the expressions are verbally expressed. That is a reading comprehension issue, not a math issue.

"A number is at least five and one quarter when divided by half and three-fourths."

In mathematics, a statement with unequal sides is referred to as an inequality. When a link leads to a non-equal comparison between two expressions or two numbers, it is referred to as an inequality in mathematics.

In this case, the equal sign "=" is replaced with any of the inequality symbols, such as greater than symbol (>), less than symbol (<), greater than or equal to symbol (≥), less than or equal to symbol (≤), or not equal to symbol (≠). There are numerous types of inequalities that can exist in mathematics, including absolute value inequality, rational inequality, and polynomial inequality.

Mary delivers 32 newspapers to her customers in 25 minutes. These deliveries represent 64% of her customers.
sveticcg [70]
<span>Ok. You would set up the problem like this: 32/x=64/100 and then cross multiply; 3200=64x; divide both sides by 64; x=50. Mary has 50 customers.</span>

A student wants to find point C on the directed line segment from A to B on a number line such that the segment is partitioned i
olganol [36]

Answer:

<u>Point C at (-18/7)</u>

Step-by-step explanation:

Point A is at -6 and point B is at 2.

So, the distance between A and B = 2 - (-6) = 8

point C on the directed line segment from A to B on a number line such that the segment is partitioned in a ratio of 3:4.

Let the distance AC = x

∴ BC = 8 - x

AC : CB = 3 : 4

∴\frac{AC}{CB} =\frac{3}{4} = \frac{x}{8-x}

Using cross multiplication

3 (8-x) = 4x

24 - 3x = 4x

24 = 7x

x = 24/7

So, Point C = -6 + 24/7 = -18/7

Point C at (-18/7)
