Answer: 23, 25, 27
Step-by-step explanation:
Let the 3 consecutive odd numbers be x, x+2 and x+4.
So
2x+(x+2)+3(x+4)=152
2x + x + 2 + 3x + 12 = 152
6x+14=152
6x = 152 - 14
x=138/6
x=23
So, the numbers are 23, 25 and 27.
Find the maximum and minimum values
Answer:
2 and 10 are the in and max
Answer:
Min = 2
Max = 10
Step-by-step explanation:
C = 2(x+y)
x ≥1
y ≥0
y ≤5 -x
The smallest y can be is zero
The smallest x can be is 1
The minimum is
C = 2 ( 0+1) = 2 ( 1) = 2
Looking for the max
y ≤5 -x
Add x to each side
x+y ≤5
The max is 5 for x+y
Substituting that into the equation for C
C = 2(5)
C = 10
Min = 2
Max = 10
123=0
4235=0
656=2
5390=2
8890=6
1001=2

What is x? The degree of the angle of x
Answer:
x = 60°
Step-by-step explanation:
All the angles in a triangle add up to 180°. So, you have this equation.
87° + 33° + x = 180°
120° + x = 180°
x = 60°
The measure of angle x is 60°.

Find the absolute maximum and absolute minimum values of f on the given interval. f(x) = 6x3 − 9x2 − 216x + 3, [−4, 5]
Answer:
absolute minimum = -749 and
absolute maximum = 467
Step-by-step explanation:
To get the absolute maximum and minimum of the function, the following steps must be followed.
First, we need to find the values of the function at the given interval [-4, 5].
Given the function f(x) = 6x³ − 9x² − 216x + 3
at x = -4;
f(-4) = 6(-4)³ − 9(-4)² − 216(-4) + 3
f(-4) = 6(-64) - 9(16)+864+3
f(-4) = -256- 144+864+3
f(-4) = 467
at x = 5;
f(5) = 6(5)³ − 9(5)² − 216(5) + 3
f(5) = 6(125) - 9(25)-1080+3
f(5) = 750- 225-1080+3
f(5) = -552
Then we will get the values of the function at the crirical points.
The critical points are the value of x when df/dx = 0
df/dx = 18x²-18x-216 = 0
18x²-18x-216 = 0
Dividing through by 18 will give;
x²-x-12 = 0
On factorizing the resulting quadratic equation;
(x²-4x)+(3x-12) = 0
x(x-4)+3(x-4) = 0
(x+3)(x-4) = 0
x+3 = 0 and x-4 = 0
x = -3 and x = 4 (critical points)
at x = -3;
f(-3) = 6(-3)³ − 9(-3)² − 216(-3) + 3
f(-3) = 6(-27) - 9(9)+648+3
f(-3) = -162-81+648+3
f(-3) = 408
at x = 4
f(4) = 6(4)³ − 9(4)² − 216(4) + 3
f(4) = 6(64) - 9(16)-864+3
f(4) = 256- 144-864+3
f(4) = -749
Based on the values gotten, it can be seen that the absolute minimum and maximum are -749 and 467 respectively

cos(0)=√2/2, and 3π/2<0<2π, evaluate sin(0) and tan(0). Sin(0)?
Answer:
Option (2)
Step-by-step explanation:
In this question we have to find the values of Sinθ and tanθ where [tex]\frac{3\pi}{2}<x<2\pi[/tex].
Cosθ = [tex]\frac{\sqrt{2}}{2}[/tex] ⇒ θ = [tex]\frac{7\pi }{4}[/tex]
[Since [tex]\text{Cos}\frac{7\pi }{4}=\text{Cos}(2\pi-\frac{\pi}{4})[/tex]
[tex]=\text{Cos}\frac{\pi }{4}[/tex]
[tex]=\frac{\sqrt{2} }{2}[/tex] ]
Since Cosine of any angle between [tex]\frac{3\pi}{2}[/tex] and 2π is positive and Sine is negative in nature,
[tex]\text{Sin}\frac{7\pi }{4}[/tex] = [tex]-\frac{\sqrt{2}}{2}[/tex]
Since, tanθ = [tex]\frac{\text{Sin}\theta}{\text{Cos}\theta}[/tex]
tanθ = [tex]\frac{\frac{-\sqrt{2} }{2} }{\frac{\sqrt{2} }{2} }[/tex]
= [tex]-\frac{\sqrt{2}}{2}\times \frac{2}{\sqrt{2}}[/tex]

High Fructose Corn Syrup (HFCS) is a sweetener in food products that is linked to obesity and type II diabetes. The mean annual consumption in the United States in 2008 of HFCS was 60 lbs with a standard deviation of 20 lbs. Assume the population follows a Normal Distribution.
a. Find the probability a randomly selected American consumes more than 50 lbs of HFCS per year.
b. Find the probability a randomly selected American consumes between 30 and 90 lbs of HFCS per year.
c. Find the 80th percentile of annual consumption of HFCS.
d. In a sample of 40 Americans how many would you expect to consume more than 50 pounds of HFCS per year.
e. Between what two numbers would you expect to contain 95% of Americans HFCS annual consumption?
f. Find the quartile and Interquartile range for this population.
g. A teenager who loves soda consumes 105 lbs of HFCS per year. Is this result unusual?
Answer:
Explained below.
Step-by-step explanation:
X = annual consumption in the United States in 2008 of HFCS
[tex]X\sim N(60, 20^{2})[/tex]
(a)
Find the probability a randomly selected American consumes more than 50 lbs of HFCS per year.
[tex]P(X>50)=P(\frac{X-\mu}{\sigma}>\frac{50-60}{20})=P(Z>-0.50)=P(Z<0.50)=0.6915[/tex]
P (X > 50) = 0.6915.
(b)
Find the probability a randomly selected American consumes between 30 and 90 lbs of HFCS per year.
[tex]P(30<X<90)=P(\frac{30-60}{20}<\frac{X-\mu}{\sigma}<\frac{90-60}{20})\\\\=P(-1.5<Z<1.5)\\\\=0.93319-0.06681\\\\=0.86638\\\\\approx 0.8664[/tex]
P (30 < X < 90) = 0.8664.
(c)
Find the 80th percentile of annual consumption of HFCS.
P (X < x) = 0.80
⇒ P (Z < z) = 0.80
⇒ z = 0.84
[tex]z=\frac{x-\mu}{\sigma}\\\\0.84=\frac{x-60}{20}\\\\x=60+(20\times 0.84}\\\\x=76.8[/tex]
80th percentile = 76.8.
(d)
In a sample of 40 Americans how many would you expect to consume more than 50 pounds of HFCS per year.
P (X > 50) = 0.6915
Number of American who consume more than 50 lbs = 40 × 0.6915
= 27.66
≈ 28
Expected number = 28.
(e)
Between what two numbers would you expect to contain 95% of Americans HFCS annual consumption?
According to the Empirical rule, 95% of the normally distributed data lies within 2 standard deviations of mean.
[tex]P(\mu-2\sigma<X<\mu+2\sigma)=0.95\\\\P(60-2\cdot20<X<60+2\cdot20)=0.95\\\\P(20<X<100)=0.95[/tex]
Range = 20 < X < 100.
(f)
Find the quartile and Interquartile range for this population.
1st quartile: Q₁
P (X < Q₁) = 0.25
⇒ P (Z < z) = 0.25
⇒ z = -0.67
[tex]z=\frac{Q_{1}-\mu}{\sigma}\\\\-0.67=\frac{Q_{1}-60}{20}\\\\Q_{1}=60-(20\times 0.67)\\\\Q_{1}=46.6[/tex]
3rd quartile: Q₃
P (X < Q₃) = 0.75
⇒ P (Z < z) = 0.75
⇒ z = 0.67
[tex]z=\frac{Q_{3}-\mu}{\sigma}\\\\0.67=\frac{Q_{3}-60}{20}\\\\Q_{3}=60+(20\times 0.67)\\\\Q_{3}=73.4[/tex]
Inter quartile range:
[tex]IQR=Q_{3}-Q_{1}=73.4-46.6=26.8[/tex]
(g)
Compute the z-score for x = 105 lbs as follows:
[tex]z=\frac{Q_{3}-\mu}{\sigma}\\\\z=\frac{105-60}{20}\\\\z=2.25[/tex]
Z-scores greater than +2.00 or less than -2.00 are considered as unusual.
Thus, the result unusual.

1. Identify the axis of symmetry for y = -3(x+3)^2-2. a. x = -2 b. x = 3 c. x = 2 d. x = -3 2. Choose the correct axis of symmetry for x = -4(y -4)^2+6 a. y = -6 b. y = -4 c. y =6 d. y = 4
Answer:
The answer is :
DDStep-by-step explanation:
Axis of symmetry is the equation where it cuts the middle of the quadratic graph.
For quadratic equation in the form of (x+a)² + b, the axis of symmetry will be (x+a) = 0 which is x = -a :
Question 1,
[tex](x + 3) = 0[/tex]
[tex]x = - 3[/tex]
Question 2,
[tex](y - 4 )= 0[/tex]
[tex]y = 4[/tex]
Answer:
[tex]\boxed{x=-3} \\ \boxed{y=4}[/tex]
Step-by-step explanation:
Axis of symmetry is a line that cuts the parabola in half touching the vertex.
Quadratic forms ⇒ y = ax² + bx + c or x = ay² + by + c
Axis of symmetry ⇒ x = [tex]\frac{-b}{2a}[/tex] or y = [tex]\frac{-b}{2a}[/tex]
First problem:
y = -3(x+3)²-2
Write in quadratic form ⇒ y = ax² + bx + c
y = -3(x² + 6x + 9) - 2
y = -3x² -18x - 27 - 2
y = -3x² -18x - 29
a = -3, b = -18
Find axis of symmetry.
[tex]x= \frac{-b}{2a}[/tex]
[tex]x=\frac{--18}{2(-3)}[/tex]
[tex]x=\frac{18}{-6}=-3[/tex]
Second problem:
x = -4(y -4)² +6
Write in quadratic form ⇒ x = ay² + by + c
x = -4(y² - 18y + 16) + 6
x = -4y² + 32y - 64 + 6
x = -4y² + 32y - 58
a = -4, b = 32
Find axis of symmetry.
[tex]y= \frac{-b}{2a}[/tex]
[tex]y=\frac{-32}{2(-4)}[/tex]
[tex]y=\frac{-32}{-8}=4[/tex]

There are two numbers, that sum up to 53. Three times the smaller number is equal to 19 more than the larger number. What are the numbers ?
Answer:
If the smaller number is x, then the equation is
. The numbers are
,
.
Answer:
x = 18; y = 35
Step-by-step explanation:
This gives us the equation:
1. x+y=53
2. 3x=y+19
3. 3x-y=19
Add the first and last line together: x+y+3x-y=53+19
Simplifies to: 4x=72
Divide by 4 to get: x = 18
Plug your numbers into the first equation to get 18+y=53; y = 35.
Answer:
The numbers are 18 and 35.
Step-by-step explanation:
The smaller number is x.
Let the other number by y.
Three times the smaller number is equal to 19 more than the larger number.
3x = y + 19
The larger number is
y = 3x - 19
the numbers add up to 53
x + y = 53
x + 3x - 19 = 53
4x = 72
x = 18
y = 3x - 19 = 3(18) - 19 = 54 - 19 = 35
The numbers are 18 and 35.

$43,870
$635
$655
$41,999
$39,784
Answer:
$41,999
Step-by-step explanation:
Annual income = 45000
monthly income = $45000/12 months = $3750
mandatory expense at 38% rule = $3750 x 0.38 = 1425
other debt = 790
tax and insurance = 340
= 1425 - 790 - 340
= 295
balance left = 295
mortgage payment = (295/8.78) x 1000
= $33,599
purchase price = monthly payment/ 1- % of down payment
= $33599/1 - 0.20
= 33599/0.80
= $41,999
Suppose that the functions g and h are defined for all real numbers x as follows.
gx = x − 3x
hx = 5x + 2
Write the expressions for (g - h)(x) and (g * h)(x) and evaluate (g + h)(−2).
Answer:
Step-by-step explanation:
Given the functions g(x) = x − 3x and h(x) = 5x + 2, we are to calculatae for the expression;
a) (g - h)(x) an (g * h)(x)
(g - h)(x) = g(x) - h(x)
(g - h)(x) = x − 3x -(5x+2)
(g-h)(x) = x-3x-5x-2
(g-h)(x) =-7x-2
b) (g * h)(x) = g(x) * h(x)
(g * h)(x) = (x − 3x )(5x+2)
(g * h)(x) = 5x²+2x-15x²-6x
(g * h)(x) = 5x²-15x²+2x-6x
(g * h)(x) = -10x²-4x
c) To get (g + h)(−2), we need to first calculate (g + h)(x) as shown;
(g + h)(x) an (g * h)(x)
(g + h)(x) = g(x) +h(x)
(g + h)(x) = x − 3x + (5x+2)
(g+h)(x) = x-3x+5x+2
(g+h)(x) =3x+2
Substituting x = -2 into the resulting function;
(g+h)(-2) = 3(-2)+2
(g+h)(-2) = -6+2
(g+h)(-2) = -4

Find local maximum or minimum of the function: f(x)= (x + 1)^2(x - 3) Local maximum point= ( , ) Local maximum value= Local minimum point = ( , ) Local minimum value=
Answer: Local Max = (-1, 0)
Local Min = (1, -8)
Step-by-step explanation:
f(x) = (x + 1)² (x - 3)
Step 1: Find the zeros
(x + 1)² = 0 --> x = -1 (multiplicity of 2)
(x - 3) = 0 --> x = 3
Step 2: Find the Vertices
x = -1 --> (multiplicity is even which means this is a vertex)
The midpoint between x = -1 and x = 3 is x = 1
Step 3: Find the Local Max and Local Min
Use the x-value above to find the y-values
f(-1) = 0 because it is a zero
f(1) = (1 + 1)² (1 - 3)
= 2²(-2)
= 4(-2)
= -8
Conclusion:
(-1, 0) is the Local Max bigger y-value
(1, -8) is the Local Min smaller y-value

The Precision Scientific Instrument Company manufactures thermometers that are supposed to give readings of 0°C at the freezing point of water. Tests on a large sample of these thermometers reveal that at the freezing point of water, some give readings below 0°C (denoted by negative numbers) and some give readings above 0°C (denoted by positive numbers). Assume that the mean reading is 0°C and the standard deviation of the readings is 1.00°C. Also assume that the frequency distribution of errors closely resembles the normal distribution. A thermometer is randomly selected and tested. A quality control analyst wants to examine thermometers that give readings in the bottom 4%. Find the temperature reading that separates the bottom 4% from the others. Round to two decimal places.
Answer:
the temperature reading that separates the bottom 4% from the others is -1.75°
Step-by-step explanation:
The summary of the given statistics data set are:
Mean [tex]\mu[/tex] : 0
Standard deviation [tex]\sigma[/tex] = 1
Probability of the thermometer readings = 4% = 0.04
The objective is to determine the temperature reading that separates the bottom 4% from the others
From the standard normal table,
Z score for the Probability P(Z < z) = 0.04
P(Z < -1.75) = 0.04
z = -1.75
Now, the z- score formula can be expressed as :
[tex]z = \dfrac{X-\mu}{\sigma}[/tex]
[tex]-1.75 = \dfrac{X-0}{1}[/tex]
-1.75 × 1 = X - 0
X = -1.75 × 1 - 0
X = -1.75
Therefore, the temperature reading that separates the bottom 4% from the others is -1.75°

Please help. I’ll mark you as brainliest if correct.
Answer:
3 × 7
Step-by-step explanation:
The order of a matrix is the number of rows and columns that it has. Rows are listed first and columns are listed second. The matrix has 3 rows going across horizontally and 7 columns going down vertically.
Therefore, the order of the matrix is 3 × 7.
Hope that helps.
