Step-by-step explanation:

I believe this is correct, if not feel free to let me know and I will fix it. I'm sorry in advance if it's incorrect.

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:

W=10

L=14

Step-by-step explanation:

Area of the rectangle is L x W=140  

            We know that L=4+W, so we have to substitute this value to obtain one equation  

            with just one unknown value;  

            (4+W) x W=140, solving the equation and making it equal to zero we obtain,

            W2 + 4W – 140 = 0, using the quadratic formula to solve we get two values for W

            One positive and one negative;

  W1=10 and W2=-14. Because we are dealing with distances, the value of

           cannot be a negative number. Therefore, the value of W is 10. With this, we

            can go back to substitute the value of W to find L,

            L = 4 + W,  

            L = 4+ 10 = 14, so the answer is W=10 and L=14

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:

5/15

Step-by-step explanation:

Out of 15, 5 are yellow. Converted to a fraction this will be 5/15. Hope this helps!! :)

Answer:

1/3

Step-by-step explanation:

Take the total number of socks and compare it to the number of yellow socks. 15 and 5. Now divide the total by the specified group (yellow socks), by doing so, you get 3.

Every 1 in 3 socks is yellow, meaning the chance of picking a yellow sock at random is 1/3.

Answer:

Time taken = 0.85 and 0.59 (Approx.)

Step-by-step explanation:

Given:

Initial height = 4 feet

Initial upward velocity = 23 f/s

Equation;

h = 4 + 23t - 16t² for h = 12 feet

Find:

Time taken

Computation:

h = 4 + 23t - 16t² for h = 12 feet

12 = 4 + 23t - 16t²

16t² -23t + 8 = 0

t = [-b±√b²-4ac] / 2a

t = [23±√23²-(4)(16)(8)] / 2(16)

t = [23±√529-512] / 32

t = [23±4.12]/32

Time taken = 0.85 and 0.59 (Approx.)

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:

a) z = 0.12

b) z = 0.52

c) z = 1.18

Step-by-step explanation:

The  z values is the area under the curve lying to its left

a) Hence, P (Z<z) = 0.5478

Taking the value of z from the standard normal table, we get -

z = 0.12

b) P (Z<z) = 0.6985

Taking the value of z from the standard normal table, we get -

z = 0.52

c) P (Z<z) = 0.8810

Taking the value of z from the standard normal table, we get -

z = 1.18

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 ...

  y = 2(3^x)

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:

2400 + (0.05X) = 2900

Therefore, the amount of sales that Liz will have to make to meet her goal is $ 10,000.

Step-by-step explanation:

Since Liz earns a salary of $ 2,400 per month, plus a commission of 5% of her sales, and she wants to earn at least  $ 2,900 this month, to find amounts of sales that will meet her goal, the following equation must be solved:

5/100 = 0.05

2400 + (0.05X) = 2900

0.05X = 2900 - 2400

0.05X = 500

X = 500 / 0.05

X = 10,000

Therefore, the amount of sales that Liz will have to make to meet her goal is $ 10,000.

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:

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).
