v ( x ) =12-2x-5 when x= -2,0,5 solve step by step
v(-2) = 11, v(0) = 7, v(5) = -3.
hope this helps! :)
[tex]v(x) = 12 - 2x - 5\\v(-2) = 12 - 2(-2) - 5\\v(-2) = 12 + 4 - 5\\v(-2) = 11\\-----------------------------\\v(0) = 12 - 2(0) - 5\\v(0) = 12 - 0 -5\\v(0) = 7\\-----------------------------\\v(5) = 12 - 2(5) - 5\\v(5) = 12 - 10 - 5\\v(5) = -3[/tex]
The sum of four consecutive integers is 274. What are the numbers that make up 274?
Answer:
Step-by-step explanation:
x + x + 1 + x + 2 + x + 3 = 274
4x + 6 = 274
4x = 274 - 6
4x = 268
x = 268/4
x = 67
===========
The numbers are 67, 68, 69, 70
In milling operations, the spindle speed S (in revolutions per minute) is directly related to the cutting speed C (in feet per minute) and inversely related to the tool
diameter D (in inches). A milling cut taken with a 2-inch high speed drill and a cutting speed of 50 feet per minute has a spindle speed of 93.5 revolutions per minute.
What is the spindle speed for a cut taken with a 4-inch high speed drill and a cutting speed of 40 feet per minute?
Answer:
The spindle speed is 37.4 rev./ min
Step-by-step explanation:
This is a form of joint variation. From the question, it can be deduced that:
S [tex]\alpha[/tex] [tex]\frac{C}{D}[/tex]
S = [tex]\frac{KC}{D}[/tex]
where K is the constant of proportionality.
Given that:
C = 50 feet per minute, D = 2 inches, S = 93.5 rev/ min, thus;
K = [tex]\frac{SD}{C}[/tex]
= [tex]\frac{2*93.5}{50}[/tex]
= [tex]\frac{187}{50}[/tex]
= 3.74
K = 3.74
When D = 4 inches, C = 40 feet /minute, the S can be determined by;
S = [tex]\frac{KC}{D}[/tex]
= [tex]\frac{3.74*40}{4}[/tex]
= 37.4 rev./ min

Solve for x. 0 = x^2 + 5x + 8
A.
B.
C.
D.
Answer:
[tex]\bold{x = \frac{-5 \± i\sqrt7}{2}}[/tex]
Step-by-step explanation:
x^2 + 5x + 8=0
Comparing with ax^2+bx+c=0
we get a = 1, b = 5, and c = 8.
Using the quadratic formula, we have:
[tex]x = \frac{-b \± \sqrt{(b^2- 4ac)}}{ 2a}[/tex]
Substituting these values, we get:
[tex]x =\frac{ -5 \± \sqrt{5^2 - 4*1*8}}{2*1}[/tex]
[tex]x = \frac{-5 \± \sqrt{25 - 32}}{ 2}[/tex]
[tex]x = \frac{-5 \± \sqrt{-7}}{ 2}[/tex]
[tex]x = \frac{-5 \± i\sqrt7}{2}[/tex]
Therefore, the solutions are:[tex]x = \frac{-5 \± i\sqrt7}{2}[/tex]

what is an example of "the inverse image"?
Given the set B = {4, 9}, the inverse image f⁻¹(B) is a collection of all real numbers whose squares are either 4 or 9. This set can be expressed as f⁻¹(B) = {-2, 2, -3, 3}.
How to determine the inverse imageLet's use mathematical language to represent the direct image as f(A), where a mapping function takes a set A as input and generates its corresponding image.
The set of inputs that correspond to a certain set B is referred to as the inverse image or f⁻¹(B).
To illustrate this concept effectively, let's analyze a practical scenario. Suppose there exists a mathematical function denoted as that maps real numbers to their respective squares by using the equation f(x) = x².
Given the set B = {4, 9}, the inverse image f⁻¹(B) is a collection of all real numbers whose squares are either 4 or 9. This set can be expressed as f⁻¹(B) = {-2, 2, -3, 3}. The elements in set B are the result of squaring the inputs corresponding to these values.

Phones-R-Us charges $16.95 per month and $0.05 per text message. Awesome Wireless charges $22.95 per
month and $0.02 per text message. During one month, how many text messages can be sent so that
Awesome Wireless cost greater than or equal to Phones R Us?
Answer:
[tex]S \leq 200[/tex]
Step-by-step explanation:
Given
Phone R-Us= $16.95 + $0.05 per SMS
Awesome Wireless = $22.95 + $0.02 per SMS
Required
Determine the number of SMS such that Awesome Wireless is greater or equal to Phone R-Us
Represent the SMS with S
For Phone R-Us, we have:
[tex]SMS = 16.95 + 0.05S[/tex]
For Awesome Wireless, we have:
[tex]SMS = 22.95 + 0.02S[/tex]
For Awesome Wireless is greater or equal to Phone R-Us, we have:
[tex]22.95 + 0.02S \geq 16.95 + 0.05S[/tex]
Collect Like Terms
[tex]0.02S - 0.05S \geq 16.95 - 22.95[/tex]
[tex]-0.03S \geq -6[/tex]
Solve for S
[tex]\frac{-0.03S}{-0.03} \geq \frac{-6}{-0.03}[/tex]
[tex]S \leq 200[/tex]
Hence: for Awesome Wireless to cost more or equal to Phone R-Us, the number of SMS must not exceed 200

1.4. Simplify: √16x16 √₁ a. 4x8 b. 4x4 C. 8x8 d. 8x4
The simplified form of the expression √16 × 16 × √₁ is 64. C.
To simplify the expression √16 × 16 × √₁, let's break it down step by step:
√16 = 4
Taking the square root of 16 gives us 4.
4 × 16 = 64
Multiplying 4 by 16 gives us 64.
√₁ = 1
Taking the square root of 1 gives us 1.
Now we can rewrite the expression with the simplified values:
√16 × 16 × √₁ = 4 × 16 × 1
= 64 × 1
= 64
None of the provided options (a. 4x8, b. 4x4, c. 8x8, d. 8x4) matches the simplified result of 64.
It appears that there might be a typographical error in the options provided.
The correct simplified value is 64, obtained by multiplying 4 and 16 together and disregarding the square root symbols since they have been evaluated.
