Answer:

the solutions are _2 and 3/4 so the answer is option D

Answer:

x = 5

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x.

Add 3 and subtract 2x from both sides of the equation:

4x (-2x) - 3 (+3) = 2x (-2x) + 7 (+3)

4x - 2x = 7 + 3

2x = 10

Next, isolate the x by dividing 2 from both sides of the equation:

(2x)/2 = (10)/2

x = 10/2

x = 5

5 is your answer for x.

Answer:

x=5

Step-by-step explanation:

4x-3=2x+7

Subtract 2x from each side

4x-2x-3=2x-2x+7

2x -3 = 7

Add 3 to each side

2x-3+3=7+3

2x = 10

Divide by 2

2x/2 =10/2

x = 5

Answer:

  -195 degrees

Step-by-step explanation:

The angle is shown as being measured CW, so in the reverse of the positive direction. The angle's terminal ray seems to be above the -x axis, making its measure more than 180°. Of the choices offered, the best seems to be ...

  -195 degrees

Step-by-step explanation:

We need to find the exact value of tan 60° in simplest form with a rational denominator.​

We know that, [tex]\tan\theta=\dfrac{\sin \theta}{\cos\theta}[/tex]

Here, [tex]\theta=60^{\circ}[/tex]

So,

[tex]\tan(60)=\dfrac{\sin (60)}{\cos(60)}\\\\=\dfrac{\dfrac{\sqrt3}{2}}{\dfrac{1}{2}}\\\\=1.73\\\\or\\\\=\dfrac{173}{100}[/tex]

Hence, this is the required solution.

Answer: Since he had fourteen, and he gave away six of them, he has eight left.

Step-by-step explanation:

The number sentence shows the number of apples Austin has left is 14 - 6 and equal to 8.

A way to express or represent numbers is through the number system.

The Number System includes any of the several sets of symbols and the rules for using them to represent numbers.

As per the given,

Total number of apples = 14

Number of apples that make a pie = 6

Left = 14 - 6 = 8

Hence "The number sentence shows the number of apples Austin has left is 14 - 6 and equal to 8".

Answer:

[tex]f(x) = 6x ^{2} + 12x - 7 \\ x = \frac{ - 6 + \sqrt{78} }{6} \: , - \frac{ - 6 - \sqrt{78} }{6} [/tex]

Given:

The quadratic function is:

[tex]f(x)=6x^2+12x-7[/tex]

To find:

The zeros of the quadratic function.

Solution:

Quadratic formula: If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then zeros of the quadratic equation are:

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

We have,

[tex]f(x)=6x^2+12x-7[/tex]

For zeros, [tex]f(x)=0[/tex].

[tex]6x^2+12x-7=0[/tex]

Here, [tex]a=6,b=12,c=-7[/tex]. Using quadratic formula, we get

[tex]x=\dfrac{-12\pm \sqrt{(12)^2-4(6)(-7)}}{2(6)}[/tex]

[tex]x=\dfrac{-12\pm \sqrt{144+168}}{12}[/tex]

[tex]x=\dfrac{-12\pm \sqrt{312}}{12}[/tex]

[tex]x=\dfrac{-12\pm 17.6635}{12}[/tex]

Now,

[tex]x=\dfrac{-12+17.6635}{12}[/tex] and [tex]x=\dfrac{-12-17.6635}{12}[/tex]

[tex]x=0.47195833...[/tex] and [tex]x=-2.47195833...[/tex]

[tex]x\approx 0.472[/tex] and [tex]x\approx -2.472[/tex]

Therefore, the zeros of the given quadratic function are 0.472 and -2.472.

Answer:

A: the function is 537(0.3x)

B: so we just plug in the numbers where x is that amount of years so

52 years from 1970 so 2022

537(1.56)

x=837.72

so the answer is 838

Answer:

108 because the full measurements is 180

Step-by-step explanation:

Answer:

54°

Step-by-step explanation:

All angles in triangle add up to 180°.

180° - 72°= 108°

108°/ 2= 54°

Answer:

Angle 2 = 124 degrees

Step-by-step explanation:

Angles 1 and 2 are corresponding angles since the two lines are parallel.

We can put both numbers into an equation.

3x + 25 = 2x + 58

Subtract both sides by 2x which will give:

x + 25 = 58

Now, we can solve for x, which is:

x = 58-25 = 33

Put back x = 33 into angle 2.

Hence, angle 2 is 2*33 + 58 = 124

Answer:

m∠2 = 124 degrees

Step-by-step explanation:

By the definition of "Same Side Corresponding Angles" the 2 angles given are congruent to each other, therefore we can say;

3x + 25 = 2x + 58

x + 25 = 58

x = 58 - 25

x = 33

Now that we have x = 33, we can substitute 33 in for x, in equation given for angle 2 to find it's measure;

∠2 = 2(33) + 58

∠2 = 66 + 58

∠2 = 124

Therefore m∠2 = 124 degrees.

Answer:

8.7 m

Step-by-step explanation:

Hi there!

[tex]5^2+h^2=10^2[/tex]

To find the height of the building, we need to isolate h on one side of the equal sign. We will do this by performing inverse operations to both sides (ex. the inverse of addition is subtraction, the inverse of multiplication is division, etc.)

Firstly, we can simplify both sides by squaring 5 and 10:

[tex]25+h^2=100[/tex]

Now subtract both sides by 25 to cancel it out on the left side and isolate h²:

[tex]25+h^2-25=100-25\\h^2=75[/tex]

Now, take the square root of both sides to isolate h:

[tex]\sqrt{h^2} =\sqrt{75} \\h=8.7[/tex]

Therefore, the height of the building is 8.7 m when rounded to the nearest tenth.

Answer:

512

Step-by-step explanation:

To effectively answer the question, let us calculate the value of m. This can be obtained as follow:

m, (m² + 4), 16m

1st term (T₁) = m

2nd term (T₂) = m² + 4

3rd term (T₃) = 16m

Common ratio = T₂/T₁ = T₃/T₂

(m² + 4) / m = 16m / (m² + 4)

Cross multiply

(m² + 4)(m² + 4) = m × 16m

(m² + 4)² = 16m²

Take the square root of both side

√[(m² + 4)²] = √(16m²)

m² + 4 = 4m

Rearrange

m² – 4m + 4 = 0

Solving by Factorisation

m² – 2m – 2m + 4 = 0

m(m – 2) – 2(m – 2) = 0

(m – 2)(m – 2) = 0

(m – 2)² = 0

Take the square root of both side

m – 2 = 0

m = 2

Thus,

1st term (T₁) = m = 2

2nd term (T₂) = m² + 4 = 2² + 4 = 8

3rd term (T₃) = 16m = 16 × 2 = 32

The sequence => m, (m² + 4), 16m

Becomes

2, 8, 32

Finally, we shall determine the 5th term. This can be obtained as follow:

1st term (a) = 2

Common ratio (r) = 2nd / 1st = 8/2 = 4

5th term (T₅) =?

T₅ = ar⁴

T₅ = 2 × (4)⁴

T₅ = 2 × 256

T₅ = 512

Therefore, the 5th term is 512

Answer:

2) 0.0914

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is of:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

A survey of 114 drivers is performed and 62 people say they will not drive until all passengers in the vehicle are buckled up.

This means that [tex]n = 114, \pi = \frac{62}{114} = 0.5439[/tex]

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

What would be the margin error for this confidence interval?

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]M = 1.96\sqrt{\frac{0.5439*0.4561}{114}}[/tex]

[tex]M = 0.0914[/tex]

Thus the margin of error is 0.0914, option 2).

Answer:

4 / x¹⁴y⁸

Step-by-step explanation:

eliminate parenthese by multiplying all exponents inside parentheses by the exponent outside the parentheses:

1/2⁶ ÷ 1/4⁴ = 1/64 ÷ 1/256 which equals 256/64 or 4

x⁻⁶y⁴ ÷ x⁸y¹² = x⁻¹⁴y⁻⁸ = 1/x¹⁴ · 1/y⁸

Answer:

  y = 2·3^x

Step-by-step explanation:

The shape of the graph appears exponential. The horizontal asymptote appears to be y=0, so there is no vertical offset. The y-intercept seems to be 2 (we can't really read the numbers), and the y-value seems to increase by a factor of 3 for each additional unit of x.

The multiplier is 2, and the base of the exponential factor is 3. That gives us ...
