Answer:
length=22
width=21
Step-by-step explanation:
let, length be x and width be y.
x=2y-20
2(x+y)=86
or, 2(2y-20+y)=86
or, 2(3y-20)=86
or, 6y-40=86
or, 6y= 126
or, y= 126/6
y= 21
x= 2×21-20 = 42-20 =22
Consider the expressions show below, please help me!
Answer:
(3x² - 6x + 11) - (10x² - 4x + 6) is equivalent to expression -7x² - 2x + 5
(-3x² - 5x - 3) - (-10x² - 7x + 2) is equivalent expression to 7x² + 2x - 5
(12x² + 6x - 5) - (5x² + 8x - 12) is equivalent expression to 7x² - 2x + 7
Step-by-step explanation:
✔️(3x² - 6x + 11) - (10x² - 4x + 6)
Open the bracket by applying the distributive property
3x² - 6x + 11 - 10x² + 4x - 6
Add like terms
-7x² - 2x + 5
Therefore:
(3x² - 6x + 11) - (10x² - 4x + 6) is equivalent to expression -7x² - 2x + 5
✔️(-3x² - 5x - 3) - (-10x² - 7x + 2)
Apply distributive property
-3x² - 5x - 3 + 10x² + 7x - 2
Add like terms
7x² + 2x - 5
Therefore:
(-3x² - 5x - 3) - (-10x² - 7x + 2) is equivalent expression to 7x² + 2x - 5
✔️(12x² + 6x - 5) - (5x² + 8x - 12)
12x² + 6x - 5 - 5x² - 8x + 12
Add like terms
7x² - 2x + 7
Therefore:
(12x² + 6x - 5) - (5x² + 8x - 12) is equivalent expression to 7x² - 2x + 7

Solve using the quadratic formula.
q2 + 69 + 9 = 0
Answer:
the value of q = -3
Step-by-step explanation:
The computation of the equation is shown below:
Given that
q^2 + 6q + 9 = 0
q^2 + 3q+ 3q + 9
q(q + 3) + 3(q + 3)
(q+3) (q+3)
q = -3
Hence, after solving it the value of q = -3

What is the period of 1-sin 2πx/3? Please explain.
Answer:
Notice, period of function sin(kx) is 2π/k where k is constant (coefficient of x ) since coefficient of x in sin(2πx/3) is k=2π/3 hence the period of sin(2πx/3) is 2π/(2π/3)=3

Find the angle of elevation to the sun given that a 7.6 meter flagpole casts an 18.2 meter shadow on the ground.
Quick Answer please!!!!
Answer:
22.7
Step-by-step explanation:
Okay so the situation given shows a right triangle with the two sides being 7.6 and 18.2. So we can find the angle of elevation using tangent, which is tan-1*7.6/18.2. I got 22.66 so 22.7
finds the value of x and Y.
2x+3y=5
X-2y=-1
Answer:
x=1
y=1
Step-by-step explanation:
2x+3y=5.........eq1
x-2y=-1........eq2
therefore: x=-1+2y
Subt. eq 3 into eq2
2x+3y=5
2(-1+2y) +3y=5
-2+4y+3y=5
7y=5+2
7y/7=7/7
y=1
therefore: Subt. y=1 into eq2
x-2y=-1
x-2(1)=-1
x-2=-1
x=-1+2
x=1

Step-by-step explanation:
The given function is a piecewise function with characteristics that vary with the value of x.
Please find attached the graph of h(x).
Reasons:
The given information is presented as follows;
From the above piecewise function, we have;
For x ≤ 0, the slope of the graph of h(x) =
For 0 < x ≤ 3, the slope of the graph of h(x) =
For x ≥ 4, the slope of the graph of h(x) =
Therefore, as we progress from left to right, the slope of h(x) increases and
the slope of the graph becomes steeper.
The graph of h(x) is plotted with the given equations using MS Excel as
shown in the attached diagram.

How do matter and energy move through an ecosystem?
Step-by-step explanation:
How Matter Moves Through Ecosystems
Decomposers release nutrients when they break down dead organisms. The nutrients are taken up by plants through their roots. The nutrients pass to primary consumers when they eat the plants. The nutrients pass to higher-level consumers when they eat lower-level consumers. When living things die, the cycle repeats.How Energy Moves Through Ecosystems
Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants. A small proportion of this chemical energy is transformed directly into heat when compounds are broken down during respiration in plants. The majority of the chemical energy stored in plants is transformed into other forms by an assortment of consumers, such as cows, rabbits, horses, sheep, caterpillars, and other insects eating plants.4.

American League baseball teams play their games with the designated hitter rule, meaning that pitchers do not bat. The league believes that replacing the pitcher, traditionally a weak hitter, with another player in the batting order produces more runs and generates more interest among fans. Below are the average numbers of runs score in American League and National League stadiums for the first half of the 2001 season. **American:** 11.1, 10.8, 10.8, 10.3, 10.3, 10.1,10.0, 9.5, 9.4, 9.3, 9.2, 9.2, 9.0, 8.3 **National:** 14.0, 11.6, 10.4, 10.3, 10.2, 9.5, 9.5, 9.5, 9.5, 9.1, 8.8, 8.4, 8.3, 8.2, 8.1, 7.9 (a) Create two box plots to display this data and comment on what you see. (b) Estimate the mean number of runs scored in American League games with a 95% CI. What concerns do you have about making a similar CI for National League games
Answer:
Kindly check explanation
Step-by-step explanation:
Given the data:
**American:**
11.1, 10.8, 10.8, 10.3, 10.3, 10.1,10.0, 9.5, 9.4, 9.3, 9.2, 9.2, 9.0, 8.3
**National:**
14.0, 11.6, 10.4, 10.3, 10.2, 9.5, 9.5, 9.5, 9.5, 9.1, 8.8, 8.4, 8.3, 8.2, 8.1, 7.9
Kindly view attached picture for boxplot :
Using the relation :
Mean ± Zcritical * s/sqrt(n)
Zcritical at 95% = 1.96
National league :
Mean = 9.58125
Standard deviation = 1.5
9.58125 - 1.96 * 1.5/4 = 8.84625
9.58125 + 1.96 * 1.5/4 = 10.31625
(8.84625 ; 10.31625)
American League :
Mean = 9.807
Standard deviation = 0.805
9.807 - 1.96 * 0.805/sqrt(14)= 9.3853152
9.807 + 1.96 * 0.805/sqrt(14) = 10.228684
(8.84625 ; 10.31625)
