Answer:
-1 = A
Step-by-step explanation:
First, you add 6+5, which equals 11. Then you have 11a = -11. Since all you have to do is multiply 11 by one and you get 11, add a negative symbol in front of it. 11 x -1 = -11

What is the coefficient of the second term of the trinomial? (In other words, what is B?)
(3x − 1)^2 = 9x^2 −Bx + 1
In the blank, write what B equals. Use only numbers - no letters or spaces.
Answer:
b = 6
Step-by-step explanation:
Let's solve for b.
(3x−1)2=9x2−bx+1
Step 1: Flip the equation.
−bx+9x2+1=9x2−6x+1
Step 2: Add -9x^2 to both sides.
−bx+9x2+1+−9x2=9x2−6x+1+−9x2
−bx+1=−6x+1
Step 3: Add -1 to both sides.
−bx+1+−1=−6x+1+−1
−bx=−6x
Step 4: Divide both sides by -x.
b = 6

Identify the initial amount a and the rate of decay r (as a percent) of the exponential function y = 8(1 – 0.15). Evaluate the function
when t = 3. Round your answer to the nearest tenth.
Answer:
Initial amount = 8
Decay rate = 15%
Step-by-step explanation:
Given the exponential function :
y = 8(1 – 0.15)
The general form of an exponential Decay function is :
A = P(1 - r)^t
Where
A = final amout ; P = initial amount ; r = days cay rate ; t = time
Hence, comparing with the equation given :
P = 8 = initial amount
r = 0.15 = 0.15 * 100% = 15% = Decay rate

Hopkins has a 1 meter wire using to make clocks. Each fourth meter is marked off and divided into 5 smaller equal lengths.
Complete question :
Mr. Hopkins has a 1 meter wire he is using to make clocks. Each fourth meter is marked off with 5 smaller equal lengths. If Mr. Hopkins bends the wire at ¾ meter, what fraction of the marks is that?
Answer:
15 th ; 15/20
Step-by-step explanation:
Length of wire = 1 m
Number of fourth length possible = 1 ÷ 1/4 = 1 * 4/1 = 4
Each fourth length divided into 5 equal sizes :
Hence. Total number of equal spaced division :
5 * 4 = 20
If wire is bent at 3/4 meter :
Fraction of the mark
3/ 4 of 20
3/4 * 20
(3 * 20) / 4
60 / 4
= 15th
= 15/ 20

Work out the size of angle x.
Not drawn accurately
132°
X Х
54°
Answer:
x = 84
Step-by-step explanation:
The sum of the angles around a point = 360°
sum the given angles and equate to 360
x + 132 + 54 + 90 = 360
x + 276 = 360 ( subtract 276 from both sides )
x = 84
Answer:
x = 84°
Step-by-step explanation:
→ Recall the fact that angles around a point add up to 360°
360 - (90 + 54 + 132 ) = x
→ Simplify
360 - 276 = x
→ Simplify again
84 = x ∴ x = 84°

In fact, weather on consecutive days depends on similar atmospheric conditions and therefore consecutive days are not independent events.With the weather forecast of the previous exercise, the probability that it rains over the weekend (either Saturday or Sunday) isA. 0.7516B. 0.3758 C. 0.2484D. Because consecutive days are not independent, we cannot compute P(rain both days) with the information given.
Question is incomplete :
The weather forecast for the weekend is a 46% chance of rain for Saturday and a 54% chance of rain for Sunday. If we assume that consecutive days are independent events, What is the probability that it rains over the weekend (either Saturday or Sunday)? Please use 3 decimal places.
In fact, weather on consecutive days depends on similar atmospheric conditions and therefore consecutive days are not independent events.With the weather forecast of the previous exercise, the probability that it rains over the weekend (either Saturday or Sunday) isA. 0.7516B. 0.3758 C. 0.2484D. Because consecutive days are not independent, we cannot compute P(rain both days) with the information given.
Answer:
0.7516 ;
D.) Because consecutive days are not independent, we cannot compute P(rain both days) with the information given.
Step-by-step explanation:
Let :
Saturday = A ; Sunday = B
P(A) = 0.46 ; P(B) = 0.54
If A and B are independent :
P(AuB) = P(A) + P(B) - P(AnB)
P(AnB) = P(A) * P(B) = 0.46 * 0.54 = 0.2484
P(AuB) = 0.46 + 0.54 - 0.2484
P(AuB) = 0.7516
If A and B are not independent, and how the weather on Saturday affect the weather on Sunday and vice versa. Hence, we cannot compute AuB

Rita is designing a building shaped like a pyramid that's cut off in a plane parallel to its base (this is called a truncated pyramid). The building has a 64×64 m end text square base and is 36 m tall. The cut off section has an a16×16m square base and is 12 m tall. What is the volume of the building? Round to the nearest cubic meter.
Answer:
64,512 m3
Step-by-step explanation:
3 1
(base area)(height) = 3 1
(64⋅64)(48) =65,536
The volume of the building is 64512 cubic meters if the pyramid that's cut off in a plane parallel to its base.
What is a right square pyramid?In geometry, it is defined as the shape having a square base with equal sides length and all the vertex of the squares joints at the top which is perpendicular to the center of the square.
We know volume for the right square pyramid is given by:
[tex]\rm V= \frac{1}{3} b\times h[/tex]
Volume for the cut off portion:
[tex]\rm v = \dfrac{1}{3}\times16\times16\times12[/tex]
v = 1024 cubic meters
Volume for the completer pyramid"
[tex]\rm V=\dfrac{1}{3}\times64\times64\times48[/tex]
V = 65536 cubic meters
Volume of the building = 65536 - 1024
= 64512 cubic meters
Thus, the volume of the building is 64512 cubic meters if the pyramid that's cut off in a plane parallel to its base.

Find the area of a trapezoidal tabletop, if its parallel sides are 2 m and 3 m long and the perpendicular distance
between them is l m.
Answer:
The area of the trapezoidal table top is 2.5 m²
Step-by-step explanation:
The area, A, of a trapezoid is given as half times the sum of the parallel side multiplied by the perpendicular distance between them
Therefore, we have;
[tex]A = \dfrac{a + b}{2} \times h[/tex]
The given parameters of the trapezoidal table top are;
The length of the parallel sides = 2 m and 3 m
The length of the perpendicular distance between the parallel sides = 1 m
Where, for the rectangular table top, we have;
'a', and 'b' = The lengths of the parallel sides = 2 m and 3 m respectively
h = The perpendicular distance between the parallel sides = 1 m
By substituting in the values, we have;
[tex]A = \dfrac{2 \ m + 3 \ m}{2} \times 1 \ m = 2.5 \ m^2[/tex]
The area of the trapezoidal table top, A = 2.5 m².

If there are 5,280 feet in a mile and 3,600 seconds in an hour, then a speed of 26 feet per second is closest to which of the following
Answer:
17.72[tex]\frac{miles}{hr}[/tex]
Step-by-step explanation:
If you are trying to take 26 ft/s to being miles per hour this is how you do it.
26 [tex]\frac{ft}{s}[/tex] * [tex]\frac{mile}{5280ft}[/tex] *[tex]\frac{3600s}{hr}[/tex]

Step-by-step explanation:
the right side of the diagram
9^2 + x^2 = 24^2
81 + x^2 = 576
x^2 = 576 + 81
x^2 = 657
x=√657
the left side of the diagram
9^2 + x^2 = 24^2
81 + x^2 = 576
x^2 = 576 + 81
x^2 = 657
x=√657
