Answer: Choice D is correct. The slope is 1.5

This means that for every hour, the temperature is increasing by 1.5 degrees Fahrenheit.

=======================================================

Work Shown:

slope = rise/run

slope = (change in y)/(change in x)

slope = (change in temperature)/(change in time)

slope = 6/4 .... see note below

slope = 3/2

slope = 1.5

note: The 6 refers to the jump from -2 to 4; the denominator 4 represents the amount of elapsed time from 8 AM to 12 PM

Together, teammates Pedro and Ricky got 2687 base hits last season. Pedro had 281 more hits than Ricky. How many hits did each p
bogdanovich [222]

Answer:

Let x be the number of hits Ricky has. Then x+277 is the number of hits Pedro has. Adding Ricky's and Pedro's hits give you 2685 hits. Therefore, x+(x+227)=2685 2x+227=2685 2x=2408 x=1204 x+277 1481 Therefore, Ricky has 1204 hits and Pedro has 1481 hits.

Find the gradient of the tangent to the curve y = 5x³ + 3x² - x + 4​
Luba_88 [7]

The gradient of the tangent to the curve y = 5x³ + 3x² - x + 4​ is 15x²+6x-1.

<h3>What is the gradient?</h3>

A differential operator is used for a function having a vector value in three dimensions to produce a vector whose three components are the partial derivatives of the function with respect to its three variables.

The given equation for the curve is;

y = 5x³ + 3x² - x + 4​

The gradient of the tangent to the curve is;

\rm y'=\frac{dy}{dx} \\\\ y'= 5x^3 + 3x^2- x + 4 \\\\\ y'=15x^2+6x-1

Hence,the gradient of the tangent to the curve y = 5x³ + 3x² - x + 4​ is 15x²+6x-1.

HELP PLS <br><br><br> all the info you need is in the picture<br><br> need to solve for x
Andrews [41]

Answer:

x=8

Step-by-step explanation:

x^2 - 48 = 2x    

x^2 - 2x - 48=0

(x+6)(x-8)=0

x+6=0     x-8=0

x= - 6         x=8

can not be negative so the answer is x=8

PLEASE HELP

The selected statistical questions are as follows:

<em>A what is the typical amount of rainfall for the month of June in the Galapagos islands</em>

<em />

<em>D how many songs does the class usually listen to each day</em>

<em />

<em>G how long does it typically take for 2nd graders to walk a lap around the track</em>

Statistical questions are known by these two main characteristics:

  • they are answered by the collection of data
  • there is always variability in the data collected

This means that the data vary.  They are not the same data.  For example, "How old is Monday?" is not a statistical question because it has one answer.

Thus, statistical questions are not answered by a single number or answer, especially when the correct answer is just one.
