Evaluate the function.<br> f(x) = 3x2 + 16<br> Find f(-1)
SIZIF [17.4K]

Answer:

f(-1)=19

Step-by-step explanation:

<u>Evaluating Functions</u>

Given a function y=f(x), evaluate the function for x=a means substituting the variable for the given value.

We have the function:

f(x)=3x^2+16

Find f(-1):

f(-1)=3(-1)^2+16

f(-1)=3(1)+16

f(-1)=3+16

\boxed{f(-1)=19}

Please help me with this question!!
stepladder [879]

Answer:

  1. rational
  2. irrational
  3. irrational
  4. irrational
  5. √7, it is irrational

Step-by-step explanation:

A <em>rational</em> number is one that can be expressed as the ratio of two integers. All fractions that have integer numerators and (non-zero) denominators are <em>rational</em> numbers. Any finite decimal number, or any repeating decimal number, is a rational number. These can always be expressed as the ratio of two integers. For example, 0.4040... = 40/99, and 0.286 = 286/1000.

To make an irrational sum, at least one of the contributors must be irrational. You want an irrational 2-number sum that has 7/8 as one of the contributors. Since 7/8 is rational, the other contributor must be irrational.

__

<u>Step 1</u>. The number 7/8 is <em>rational</em>.

<u>Step 2</u>. The desired sum is <em>irrational</em>.

<u>Step 3</u>. The rule <em>rational + </em><em>irrational</em><em> = irrational</em> applies.

<u>Step 4</u>. An <em>irrational</em> number must be chosen.

Step 5. √7 will produce an irrational sum, because <em>it is irrational</em>.

Given H = f(t) where H is the height in meters of an object and t is the time in seconds since it was launched, which of the fol
dangina [55]

Answer:

Recall that the height of the object, in meters, is a function of elapsed time, in seconds. Thus what f(8)=12 means is that the object is at a height of 8 meters when 12 seconds have passed since its launch.

Look at the drawing of a triangle within a rectangle. The triangle and the rectangle have the same base, b, and height, h.
lara [203]

the total area of sections 1 and 2 is 48  square units !

<u>Step-by-step explanation:</u>

Here we have ,  The triangle and the rectangle have the same base, b, and height, h.  If the area of the triangle is 48 square units,We need to find what is the total area of sections 1 and 2 . Let's find out:

According to question , we have a triangle with same base and height as of rectangle inside a rectangle ! Following are the parameters of rectangle:

Length= b\\width= h\\

but , Area of rectangle = length(width) . Also , Area of triangle :

⇒ \frac{1}{2} (b)(h) = 48

⇒ (b)(h) = 96

So , Area of rectangle =  (b)(h) = 96 . Total area of section 1 & 2 is given by :

⇒ 96=48+Area

⇒ Area=48

Therefore , the total area of sections 1 and 2 is 48 square units !
