Answer:
963
Step-by-step explanation:
Evaluate 6 | - 5 , then the outside part, that is
6 | - 5 ( with a = 6 and b = - 5 )
= (- 5)² + 6 = 25 + 6 = 31
Now evaluate 2 | 31 ( with a = 2 and b = 31 )
= 31² + 2 = 961 + 2 = 963
Solve 2x^2 - x ≥ -5. Show your work.
Answer:
[tex](x-\frac{1}{4})^{2} \geq \frac{-39}{16}[/tex]
Step-by-step explanation:
Rewrite into standard form:
[tex]2x^{2} -x+5 \geq 0[/tex]
Complete the square:
[tex]2(x-\frac{1}{4} )^{2} + \frac{39}{8} \geq 0[/tex]
Subtract [tex]\frac{39}{8}[/tex] from both sides:
[tex]2(x-\frac{1}{4})^{2} \geq \frac{-39}{8}[/tex]
Divide both sides by 2:
[tex](x-\frac{1}{4})^{2} \geq \frac{-39}{\frac{8}{2}}[/tex]
Simplify:
[tex](x-\frac{1}{4})^{2} \geq \frac{-39}{16}[/tex]

5) So far you have a MP3 Player with 0.5 GB of music already stored on the MP3 player and know that each song is about 0.002 GB of memory. What are the possible numbers of additional songs that you can put on the MP3 player if it holds at most 2 GB?
Answer: Any whole number between 0 and 750, including both endpoints.
One example could be 700 additional songs.
==================================================
Explanation:
x = number of additional songs, some nonnegative whole number
1 song takes up 0.002 GB, so x of them take up 0.002x GB of memory.
Add on the 0.5 GB already used to get the expression 0.002x+0.5 to represent the total amount of storage taken up. We want this expression to be 2 or smaller.
[tex]0.002x + 0.5 \le 2\\\\0.002x \le 2-0.5\\\\0.002x \le 1.5\\\\x \le 1.5/0.002\\\\x \le 750\\\\[/tex]
This says the most songs we can add are 750.
Because x is the number of songs, it doesn't make sense to have x be negative. This means [tex]x \ge 0[/tex] or [tex]0 \le x[/tex] is the case as well.
Combining [tex]0 \le x[/tex] and [tex]x \le 750[/tex] produces the compound inequality [tex]0 \le x \le 750[/tex]
The number of additional songs is any whole number between 0 and 750, including both endpoints.
The roster notation of this set could look like this: {0, 1, 2, ..., 748,749,750}
The triple dots indicate "keep this pattern going". That way we don't have to fill in all 751 values which would be a tedious process.
So you can add on something like 700 songs because it's between those endpoints mentioned, but cannot add something like 800 songs.
Answer:
0 - 750 additional songs
Step-by-step explanation:
current: 0.5 mb
remaining: 2-0.5=1.5 mb
each song: 0.002 gb
take remainig amount of space: 1.5 mb and divide by how much space each song takes: 0.002 mb to find out how many songs can fit in 1.5 mb of space
work:
(total amount of storage-used amount of storage)/storage per song
(2.0-0.5)/0.002
= 1.5/0.002
= 750 songs
what are the possible number of additional songs?
anything up until 750.
I need help solving for Y
Answer:
y=24
Step-by-step explanation:
since the triangles are similar, their sides are all in proportion
meaning:
[tex] \frac{20}{15} = \frac{32}{y} [/tex]
simplify the fraction
[tex] \frac{4}{3} = \frac{32}{y} [/tex]
cross multiply once the fraction is simplified
[tex]96 = 4y[/tex]
y=24
Answer:
y = 24
Step-by-step explanation:
the first triangle 20 : x : 32
the 2nd triangle 15 : 21 : y
Solve the equation of two triangles by similarity
x = [tex]\frac{21 * 20}{15}[/tex] = 28
y = [tex]\frac{21 * 32}{28}[/tex] = 24

Triangle UVW is dilated by a scale factor of 3 to form triangle UVW. Side VW
measures 54. What is the measure of side VW?
Answer:
162
Step-by-step explanation:
In geometry, dialation is increasing the size of a shape on a plane. Since the porblem you have givine isn't requiring the triangle to be centered around a point, this is fairly easy. If you are increasing UVW by a scale factor of 3, you are multiplying each side by 3. So, if side VW is 54, after dilation VW' will have a length of 162. (54 × 3 = 162)
Hope that helped!

Find the EXACT distance between the two points.
(5,−4) and (3,5)
Answer:
√85
Step-by-step explanation:
The distance formula is used for this purpose.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((3 -5)² +(5 -(-4))²) = √((-2)² +9²) = √(4 +81)
d = √85 . . . . the distance between the two points
The surface of an office desk has a perimeter of 12 feet and an area of 8 square feet. What are the dimensions of the desk?
____feet by ___feet
HELP ME PLEASEE!
Answer:
4 feet by 2 feet ig? am not quit sure
Step-by-step explanation:
we say that length=x width=y
2(x+y)=12
xy=8 x=8/y
2(8/y + y)=12
8/y+y^2=6y
y^2-6y+8=0
(y-2)(y-4), so y=2 y=4
then we input this two numbers in xy=8
so, x=4 x=2
1, y=2 x=4
2, y=4 x=2
most likely the lengths is going to be 4 so that means the width is going to be 2.

equation where slope = 7/2 and y-intercept is -15
Answer:
y = 7/2x - 15
Step-by-step explanation:
y = mx + b
if slope is 7/2, m= 7/2
y = 7/2x + b
if y-intercept is -15, y = -15, x = 0
-15 = 7/2(0) + b
b = -15
then
y = 7/2x - 15

167<6+7(2+7r)
what is it please help
Answer:
3 < r
Step-by-step explanation:
167<6+7(2+7r)
distribute the 7 to the 2 and 7r
7 * 2 = 14 and 7 * 7r = 49r
167 < 6 + 14 + 49r
combine like terms: 6 + 14 = 20
167 < 20 + 49r
subtract 20 from both sides
147 < 49r
divide both sides by 49
3 < r

At the beginning of the year, Wyatt had $40 in savings and saved an additional $14 each week thereafter. Julian started the year with $20 and saved $19 every week. Let WW represent the amount of money Wyatt has saved tt weeks after the beginning of the year and let JJ represent the amount of money Julian has saved tt weeks after the beginning of the year. Write an equation for each situation, in terms of t,t, and determine the interval of time when Wyatt has more in savings than Julian.
Answer:
4 weeks
Step-by-step explanation:
Wyatt's equation:
t=14w+40
Julian's equation:
t=19j+20
Since both equations equal the same thing, or t, we can equal them against each other as 1 equation
14t+40=19t+20
(subtract 20 from both sides)
14t+20=19t
(subtract 14t from both sides)
20=5t
(divide both sides by 5)
t=4 weeks
What is the next fraction in this sequence? Simplify 3/14,2/7,5/14,3/7, its due today please help
The next fraction in the given sequence is; 7/14
We are given the sequence;
3/14, 2/7, 5/14, 3/7.
To get the next fraction in the sequence, we have to find the pattern of the differences.
Difference between first and second term is;
2/7 - 3/14 = 1/14
Similarly, for 2nd and 3rd term;
Difference = 5/14 - 2/7
Difference = 1/14
Therefore,the next fraction in the sequence will be gotten by adding 1/14 to 3/7
Next fraction = 3/7 + 1/14
Next fraction = 7/14
