Answer:

y = 9.75

Step-by-step explanation:

(4y - 3)2 = 72

Opening the brackets;

8y - 6 = 72

8y = 72 + 6 = 78

y = 78 ÷ 8 = 9.75

Answer:

[tex]y = \frac{3+6\sqrt{2}}{4}\text{ and } y = \frac{3-6\sqrt{2}}{4}[/tex]

Step-by-step explanation:

Given quadratic equation,

[tex](4y-3)^2=72[/tex]

[tex]\implies 4y - 3 = \pm \sqrt{72}[/tex]   ( Taking root on both sides )

[tex]4y=3 \pm 6\sqrt{2}[/tex]     ( Additive property of equality ),

[tex]y = \frac{3 \pm 6\sqrt{2}}{4}[/tex]   ( Division property of equality )

[tex]\implies y = \frac{3+6\sqrt{2}}{4}\text{ or }y =\frac{3-6\sqrt{2}}{4}[/tex]

Hence, the solution of the given equation is,

[tex]\implies y = \frac{3+6\sqrt{2}}{4}\text{ and }y =\frac{3-6\sqrt{2}}{4}[/tex]

Answer:

Option C is correct.

Step-by-step explanation:

Andy tested gemstones already = 30

Jacob tested gemstones already = 40

Total gemstones tested by Andy and Jacob already = 30+40 = 70

Andy continue to test gemstones per hour = 30

Jacob continue to test gemstones per hour = 25

Total gemstones tested by Andy and Jacob per hour = 30 +25 = 55

The total number of gemstones tested by Andy and Jacob after x hours will be: 55x

So, the equation will be: f(x) = 55x + 70

After 5 hours i.e. x =5

f(5) = 55(5) + 70

f(5) = 275 + 70

f(5) = 345

Andy and Jacob will have tested 345 gemstones in 5 hours.

So, Option C is correct.

Answer:

The function describing the relationship of V and t is V = 3t²

Step-by-step explanation:

* Lets explain the meaning of direct variation

- The direct variation is a mathematical relationship between two

  variables that can be expressed by an equation in which one

  variable is equal to a constant times the other

- If Y is in direct variation with x (y ∝ x), then y = kx, where k is the

 constant of variation

* Now lets solve the problem

# V is varies directly with the square  of t

- Change the statement above to a mathematical relation

∴ V ∝ t²

- Chang the relation to a function by using a constant k

∴ V = kt²

- To find the value of the constant of variation k substitute V and t

 by the given values

∵ t = 6 when V = 108

∵ V = kt²

∴ 108 = k(6)² ⇒ simplify the power 2

∴ 108 = 36k ⇒ divide both sides by 36 to find the value of k

∴ 3 = k

- The value of the constant of variation is 3

∴ The function describing the relationship of V and t is V = 3t²

Answer:

The answer would be B. The highest price and the lowest price of the game differ by less than $14. Hope this helps!

B. The highest price and the lowest price of the game differ by less than $14.

Given is that the the price of Song Hero showed greater variability. This means their prices are more varied in range.

If Song Hero was priced between $35 and $49 during the 10-month period, This means the variability of Star chasers is less than [tex]49-35=$14[/tex]

Since, $14 is Song Hero’s range, the range for Star chasers should be less.

Therefore, option B is correct.

Answer:

A. [tex]g(x)=(x-4)^2[/tex]

Step-by-step explanation:

The graph of [tex]f(x)=x^2[/tex] is transformed to obtain the graph of g(x).

We can see from the diagram that, f(x) is shifted 4 units to the right to obtain the graph of g(x).

Therefore [tex]g(x)=f(x-4)[/tex].

Hence the equation of g(x) is

[tex]g(x)=(x-4)^2[/tex]

The correct answer is A.

The equation of the graph of g(x) is g(x) = (x - 4)²

From the graph shown, we can see that the f(x) = x² as shown is shifted   4 units to the right to obtain the graph of g(x).

Then, we have that this shift can be achieved by replacing x in the equation of f(x) with x - 4 to represent the horizontal shift.

We have the equation of the graph of g(x), to be;

g(x) = (x - 4)²

This equation represents a horizontal shift of the graph of f(x) by by 4 units to the right, as g(x) remains the same shape f(x) but is  shifted horizontally to the right by 4 units.

Answer:

34.480000000000000000000000

Step-by-step explanation:

Final answer:

To combine the expression 4 log x - 6 log (x+2) into a single logarithm, we use the exponentiation and division rules for logarithms to obtain log((x^4)/(x+2)^6).

Explanation:

To write the expression 4 log x - 6 log (x+2) as a single logarithm, we can apply log rules.

The logarithm of a number raised to an exponent is the product of the exponent and the logarithm of the number: log(x^n) = n log x.

The logarithm of a product of two numbers is the sum of the logarithms of the two numbers: log xy = log x + log y.

The logarithm of the number resulting from the division of two numbers is the difference between the logarithms of the two numbers: log(x/y) = log x - log y.

Using these rules, we can

rewrite the given expression:

4 log x - 6 log (x+2) can be rewritten as log(x^4) - log((x+2)^6), which simplifies to log((x^4)/(x+2)^6) according to the division rule for logarithms.

The expression [tex]4 log x - 6 log (x+2)[/tex] can be simplified as a single logarithm by using the logarithm properties of exponents and division, resulting in [tex]log(x^4 / (x+2)^6).[/tex]

The student is asking to write the expression [tex]4 log x - 6 log (x+2)[/tex] as a single logarithm. To do this, we recall two important properties of logarithms:

Using these properties, we can rewrite the expression:

Therefore, the expression [tex]4 log x - 6 log (x+2)[/tex] written as a single logarithm is[tex]log(x^4 / (x+2)^6).[/tex]

Answer:

1. D ∠4 and ∠5

2. C 37°

3. A 50°

Step-by-step explanation:

1. Complementary angles are those that add up to 90°.

From the diagram you can see that angles 4 and 5 together form right angle, so angles 4 and 5 are complementary.

2. Angles 1 and 4 are vertical angles. Vertical angles have the same measure, so

∠4=∠1=37°

3. From 1,

∠4+∠5=90°

From 2

∠1=∠4

Since ∠1=40°, then ∠4=40°

So,

∠5=90°-40°=50°

Answer: $8.2

Step-by-step explanation:

Answer:

8.2 dollars an hour is the answer

Step-by-step explanation:

50.43 divided by 6.15 is 8.2

Answer:

1.4 inches

Step-by-step explanation:

The picture is a rectangle 8 cm by 6 cm. The area of a rectangle is length * width. The area of the picture is 8 cm * 6 cm = 48 cm^2

After the mat is applied, the area doubles, so the new area will be 2 * 48 cm^2 = 96 cm^2.

Let the width of the mat be x. The mat has the same width all around the rectangular picture, so it adds x on each side of the length and x on each side of the width.

old length: 8

new length: 2x + 8

old width: 6

new width: 2x + 6

Area of the new rectangle with mat = new length * new width

area = (2x + 8)(2x + 6)

The new area is 96, so that give us an equation.

(2x + 8)(2x + 6) = 96

Use FOIL on the left side:

4x^2 + 12x + 16x + 48 = 96

Combine like terms, and subtract 96 from both sides:

4x^2 + 28x - 48 = 0

Divide both sides by 4:

x^2 + 7x - 12 = 0

To factor the trinomial, we need two numbers that add to 7 and multiply to -12. There are no such numbers, so we need to use the quadratic formula.

x = [-b +/- sqrt(b^2 - 4ac)]/(2a)

x = [-7 +/- sqrt(7^2 - 4(1)(-12)]/[2(1)]

x = [-7 +/- sqrt(49 + 48)]/2

x = [-7 +/- sqrt(97)]/2

x = 1.4 or x = -8.4

Since the mat cannot have a negative width, the negative solution is discarded.

Answer: The width of the mat is 1.4 inches.

Answer:

The area of one of the bases is 0.96 ft²

The area of each lateral rectangular face is 4.8 ft²

The surface area of the paperweight is 6.72 ft²

Step-by-step explanation:

we know that

The surface area of the rectangular prism is equal to

SA=2B+LA

where

B is the area of one of the bases

LA is the lateral area of the prism

Find the area of one of the bases B

B=(0.8)(1.2)=0.96 ft²

Find the lateral area LA

The lateral area is the area of each lateral rectangular face

LA=2[(0.8)(1.2)]+2[(1.2)(1.2)]=4.8 ft²

Find the surface area

SA=2(0.96)+4.8=6.72 ft²

Answer: 1.44, 0.96, and then 6.72.

Answer:

The value of x is 10, and the value of y is 6

Step-by-step explanation:

ABC and GEF are congruent

so

x - 8 = 2

x = 10

x - y = 4

10 - y = 4

y = 10 - 4

y = 6

Answer

x = 10, y = 6

Answer:

x = 10 and y = 6

Step-by-step explanation:

In the given figure ΔABC and ΔGEF are congruent which means all the corresponding sides of the given triangles should be congruent.

So measure of AC = mfg

x - 8 = 2

x = 2 + 8

x = 10

Similarly mBC = mEF

x - y = 4

10 - y = 4

y = 10 - 4 = 6

Therefore, answer are x = 10 and y = 6

Answer:

1. Sine (sin) 2. Cosine (cos) 3. Tangent (tan) 4. Secant (sec) 5. Cosecant (csc) 6. Cotangent (cot) These functions are used to relate the angles of a triangle with the sides of that triangle.

Step-by-step explanation:

Sine and cosine functions are examples of trigonometric functions that generate periodic waves. These waves can be represented in equations like y = A sin(wt + p) and x(t) = A cos(wt + p), where A is the amplitude, w is the angular frequency, t is the time, and p is the phase shift.

Trigonometric functions like the sine, cosine, and tangent functions are often used to generate periodic waves in mathematics and physics. For instance, simple harmonic motion, which is related to alternating cycles in physics, can be represented by sine and cosine functions.

Let's consider the example of a bouncing object on a spring. The object's position over time can be represented by a sine function, resulting in a wave-like pattern on a graph. A sine function generating a periodic wave would look like this: y = A sin(wt + p), where A is the amplitude, w is the angular frequency, t is the time, and p is the phase shift.

Another example is a cosine function that might represent a phase-shifted wave, like this: x(t) = A cos(wt + p). Again, A is the amplitude, w is the angular frequency, t is the time, and p is the phase shift. This function is effectively identical to the sine function but is shifted to the right on the x-axis.

Answer:

C. 66

Step-by-step explanation:

32 + x =98

The sum of interior angles of a triangle add up to the exterior opposite angle;

solving for x yields;

x = 98 - 32

x = 66 degrees

Answer:

x = 66°

Step-by-step explanation:

Since DAC is a straight line, the angles must add up to 180° and 98° is given so the missing angles is 180° - 98° = 82°

Angles in a triangle add up 180° and 32° and 82° are given →

x + 32° + 82° = 180°

x + 114° = 180°

x = 66°

Answer:

145

Step-by-step explanation:

The volume of the rectangular prism bin is area of base * height.

Base/top is a square, so area would be 150 * 150 = 22,500

Thus, volume of bin = 22,500 * 210 = 4,725,000

Using volume of sphere formula and given radius of each ball is 16cm, we can say that

Volume of 1 Ball = [tex]\frac{4}{3}\pi r^3 = \frac{4}{3}\pi (16)^3=17,157.28[/tex]

Since, 190% is including the packing, we can take volume of 1 ball (inclusive of packaging) to be  1.9 * 17,157.28 = 32,598.83

How many of this will fit in the bin, we divide bin volume by this:

Number of Balls = [tex]\frac{4,725,000}{32,598.83}=144.94[/tex]

Rounding, we can say that we can fit 145 balls, 2nd answer choice is right.
