Answer:
131.63
Step-by-step explanation:
Sample method: Use properties of operations. Let x represent the markup.
x98.75=33.3100 Write the proportion.
x98.75=0.333 Divide 33.3 by 100.
98.75 · x98.75=(0.333)∙98.75 Multiplication Property of Equality
x=32.88 Simplify.
Add the markup to the wholesale cost.
The selling price is $98.75+$32.88 or $131.63.

Raise these monomials to their given powers.
(5x2y3) to the power of 2 (x2 means x squared, y3 means y cubed)
(-4ax3) to the power of 3 (ax3 means ax cubed)
(-2m3n2t) to the power of 4 (2m3 means 2m cubed, n2 means n cubed)
(-a2bc3) to the power of 5 (-a2 means -a squared, c3 means c cubed)
Answer:
For the last one,it is -a^10b^5c^15
Step-by-step explanation:
When you raise monomials to a power, you multiply each thing inside the parenthases by the power you are raising it to. (-a^2bc^3)^5=(-a^5x3)(b^1x5)(c^3x5)=-a^10b^5c^15

find the value a and b for h(x)=x^2+ax+b so h(1)=0 and h'(1)=4
Answer:
a= -14/3b= 11/3Step-by-step explanation:
Given Function h(x) = x^2 + ax + bh(1) = 0h'(1) = 4To findValues of a and bSolutionh(1) = 0 ⇒
1^2 + 1*a + b = 0 ⇒a + b = -1 ------------------> (1)h'(1) = 4 ⇒ h(4) = 1 ⇒
4^2 + 4*a + b = 1 ⇒4a + b = - 15 ------------------> (2)Considering the equation (1) in the equation (2)
3a - 1 = -153a = -14a = - 14/3and
b = -1 - a b = -1 + 14/3 b = 11/3Round 1.029 to the nearest hundredth.

During a musical an orchestra is playing. As the music plays, the volume changes in the beginning of the piece can be modeled by the equation s = 10│x - 4│+ 50 where s represents the sound level in decibels and x represents the number of measures of music played. Explain in words each step to find the following question:
At what number(s) measures played would the sound level be at 80 decibles?
( I need the answers, plus the steps please and thank youuu :)
Answer:
Kindly check explanation
Step-by-step explanation:
Given the equation:
s = 10│x - 4│+ 50
Where s = sound level in decibels
x = number of measures of music played
Step 1:
Subtract 50 from Both sides
s - 50 = 10│x - 4│+ 50 - 50
s - 50 = 10│x - 4│
For s = 80
80 - 50 = 10│x - 4│
30 = 10│x - 4│
Clear the absolute value sign
± 30 = 10x - 40
Hence ;
Lower value :
- 30 + 40 = 10x
10 = 10x
x = 1
Upper value :
+30 + 40 = 10x
70 = 10x
x = 7

Which translation maps the vertex of the graph of the function f(x) = x2 onto the vertex of the function g(x) = x2 + 2x
+1?
Oright 1 unit
o left 1 unit
Oright 2 units
left 2 units
Answer:
The translation is left 1 unit, up 5 units ⇒ A
Step-by-step explanation:
Let us revise the rules of translation of a function
If the function f(x) translated horizontally to the right by h units, then its image is g(x) = f(x - h)
If the function f(x) translated horizontally to the left by h units, then its image is g(x) = f(x + h)
If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k
If the function f(x) translated vertically down by k units, then its image is g(x) = f(x) - k
The vertex form of the quadratic function is f(x) = ax² + bx + c, where a, b, and c are constant is f(x) = a(x - h)² + k, where h = and k = f(h)
You will use the vertex form to find the translation
∵ g(x) = x² + 2x + 6
∴ a = 1 and b = 2
→ use the rule of h to find it
∴ h =
∴ h = -1
→ Use it to find k
∵ g(h) = k
∴ k = g(-1)
→ Substitute x by -1 in g to find k
∴ k = (-1)² + 2(-1) + 6 = 1 - 2 + 6
∴ k = 5
→ Substitute the values of h and k in the vertex form above
∴ g(x) = 1(x - -1)² + 5
∴ g(x) = (x + 1)² + 5
→ By using the 2nd and 3rd rules of translation above
∴ f(x) is translated 1 unit to the left and 5 units up
∴ The translation is left 1 unit, up 5 units
Answer:
it's A. left 1 unit
