What’s the square unit ?

Answer:

x < -10

Step-by-step explanation:

Solve the inequality.

-2x + 4 > 24     Subtract 4 from both sides

-2x > 20           Divide both sides by -2

x < -10              We must flip the inequality sign because we divided by a negative number in the last step.

When you graph, draw a number line. Then, draw a circle on top of -10. Since x is less than -10, the arrow goes to the left of -10. Additionally, the circle on top of -10 will be an open circle because the inequality sign is a less than, not a less than or equal to.

The volume of the three-dimensional figure formed if the  two-dimensional figure is rotated 360 degrees is 37.70 in³

Volume is the amount of space occupied by a three dimensional shape or object.

The volume of the three dimensional shape is:

Volume = volume of cylinder + volume of cone =  (π(2²) * 2) + [(1/3) * π * (2²) * 3] = 37.70 in³

The volume of the three-dimensional figure formed if the  two-dimensional figure is rotated 360 degrees is 37.70 in³

Step-by-step explanation:

Top left box

f(x) = 2x² + 4

g(x) = 2f(x) - 3

Top right box

f(x) = 2x² + 4

g(x) = 2f(x) + 3

Bottom left box

f(x) = 2x² - 4

g(x) = 2f(x) - 3

Bottom right box

f(x) = 2x² - 4

g(x) = 2f(x) +3

The volume of the cylinder in cubic meters is 20.886 m^3

We know that the volume is the area of the base times the height.

In this case, the diameter of the base is 18 ft, so the radius (half of that) is:

R = 18ft/2 = 9ft

Then the area of the base is:

B = 3.14*(9ft)^2 = 254.34 ft^2

And the height is 2.9 ft, then the volume is:

V = (2.9 ft)*254.34 ft^2 = 737.586 ft^3

Now, we know that:

1ft = 0.3048 m

if we cube both of these

1 ft^3 = (0.3048 m)^3 = 0.0283 m^3

Now we can change the unis of our volume:

V = 737.586 ft^3 = 737.586*0.0283 m^3 = 20.886 m^3

Given function:  [tex]f(x)=x^2+4x-3[/tex]

Axis of symmetry

[tex]\textsf{Axis of Symmetry formula : }x=-\dfrac{b}{2a}[/tex]

for a quadratic equation in standard form [tex]y=ax^2+bx+c[/tex]

[tex]\implies \textsf{Axis of symmetry}: x=-\dfrac{4}{2}=-2[/tex]

Maximum/Minimum point (vertex)

The max/min point is the turning point of the parabola.

The x-value of the turning point is the axis of symmetry.

[tex]\implies \textsf{Turning point}:f(-2)=(-2)^2+4(-2)-3=-7[/tex]

Turning point (vertex) = (-2, -7)

As the leading coefficient is positive, the parabola opens upwards.  Therefore, the turning point  (-2, -7) will be a minimum.

Domain & Range

Domain: input values → All real numbers

Range: output values → [tex]x\geq -7[/tex]  [as (-2, -7) is the minimum point]

End behavior

As the leading degree is positive and the leading coefficient is positive:

[tex]f(x) \rightarrow + \infty, \textsf{ as } x \rightarrow - \infty[/tex]

[tex]f(x) \rightarrow + \infty, \textsf{ as } x \rightarrow + \infty[/tex]

Answer:

[tex]\left(\dfrac53,\dfrac{14}{3}\right)[/tex]

Step-by-step explanation:

Equation 1:  y = 4x - 2

Equation 2:  y = x + 3

Subtract Equation 2 from Equation 1 and solve for x:

⇒ 0 = 3x -5

⇒ 3x = 5

⇒ x = 5/3

Substitute found value of x into one of the equations and solve for y:

⇒ y = 5/3 + 3

⇒ y = 14/3

Therefore, the solution of the system of equations is:

the study is on teens, and its impossible to survey every teen since they didnt specify how many teens there were. so the answer is a, survey 100 teens.

Using the normal distribution, it is found that there is a 0.0125 = 1.25% probability that a randomly selected 10th grade boy exceeds 70 in.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, the mean and the standard deviation are, respectively, given by [tex]\mu = 63.5, \sigma = 2.9[/tex].

The probability that a randomly selected 10th grade boy exceeds 70 in is one subtracted by the p-value of Z when X = 70, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{70 - 63.5}{2.9}[/tex]

Z = 2.24

Z = 2.24 has a p-value of 0.9875.

1 - 0.9875 = 0.0125.

0.0125 = 1.25% probability that a randomly selected 10th grade boy exceeds 70 in.

The probability of pulling out a blue ball is 1/3

This is a likelihood or chance that an event will occur. Mathematically:

Probability = Expected/Total outcome

If someone randomly reaching into a bag of 8 red table tennis balls and 4 blue table tennis balls, the total outcome is:

Total outcome = 8 + 4 = 12 balls

If a blue ball is pulled out then the probability of pulling it out is:

Pr(blue ball) = 4/12 = 1/3

Answer:

Step-by-step explanation:

a. These triangles are proportional. Identify the corresponding sides for all three sides.

40 AB------30 YZ

50 AC-------37.5 XY

60 BC---------45 XZ

b. Set up fractions with your corresponding sides to show proportionality. Make sure to show your work for all three side pairs demonstrating that the fractions are proportional.

Fraction: 3/4

40 x3/4 = 30

50 x 3/4 =  37.5

60 x 3/4 = 45

c. Are the triangles similar? If so explain why. If not, explain why not. Your work from Part A & B may help with this.

The triangles are similar

The Side-Side-Side Similarity Theorem states: “If all three corresponding sides of two triangles are proportional, then the triangles are similar".

Answer:

A. Sides AB, BC, and CA are proportional to YZ, ZX, and XY, respectively.

B. 3/4(AB) = YZ, 3/4(BC) = ZX, 3/4(CA) = XY

3/4 x 40 = 30    3/4 x 60 = 45    3/4 x 50 = 37.5

C. Yes, by SSS

Step-by-step explanation:

a. and b. are self-explanatory, but I will explain c.

When testing if two triangles are similar, they have to have the same except for scaling and flipping or turning. You know triangles are the same if all three sides are equal (SSS), two angles are equal (AA), or if there are two equal sides with an equal angle between them (SAS).

Since similar tringles can be scaled, these rules turn into if all three sides are proportional (SSS), two angles are equal (AA), or if there are two proportional sides with an equal angle between them (SAS).

These two triangles have proportional sides, so SSS applies and they are similar.
