pleasee guys i need help

Answer:  -6 and 6

Step-by-step explanation:  

Possible factors that could produce 3x² + 6x +3 are  (x + 1)(3x + 3)

the solution for values of x: x+1=0, x= -1  3x+3=0,  3x= -3 . x= -1 . Same.

Possible factors that could produce 3x² - 6x +3 are  (x - 1)(3x - 3)

the solution for values of x: x-1=0, x= 1  3x-3=0,  3x= 3 . x= 1 . Same.

From the attached graph of the possible equations, you can see that 9 and -9 won't produce ONE real solution. They each have "zeros" at two points on the x-axis. That is two solutions that would make x = 0.

The equations with -6 and +6 each touch the x-axis at only one point each.

Given:

Elena has a pet parakeet that weighs 6 when measured in one unit and 170 when measured in a different unit.

6__________ = 170______

To find:

The correct units from grams and ounces for these blanks.

Solution:

We know that, 1 ounce is greater than 1 gram.

1 ounce = 28.3495 grams

Multiply both sides by 6.

6 ounces = 170.097 grams

Approximate the values to the nearest whole number.

6 ounces = 170 grams

Therefore, 6 ounces = 170 grams.

Answer:

KP = 6

Step-by-step explanation:

From the information given, K is the centroid.

Therefore, based in the centroid theorem:

KP = ⅓(AP)

AP = 18

Plug in the value of AP into the equation

KP = ⅓(18)

KP = 6

Answer:

x = 6

Step-by-step explanation:

First, subtract 7 from both sides to get x alone. That will give you 4x = 24 .

Then divide both sides by 4 to remove the coefficient of x. That means x = 6.

4x+7=31

    -7   -7

4x=24

÷4   ÷4

x  =  6

The required value is [tex]\csc A=\dfrac{5}{4}[/tex].

Important information:

We need to find the exact value of csc A.

Formulae used: If angle A is in Quadrant I.

[tex]\cos A=\dfrac{1}{\sec A}[/tex]

[tex]\sin A=\sqrt{1-\cos^2 A}[/tex]

[tex]\csc A=\dfrac{1}{\sin A}[/tex]

Using these formulae, we get

[tex]\cos A=\dfrac{3}{5}[/tex]

And,

[tex]\sin A=\sqrt{1-\left(\dfrac{3}{5}\right)^2}[/tex]

[tex]\sin A=\sqrt{1-\dfrac{9}{25}}[/tex]

[tex]\sin A=\sqrt{\dfrac{16}{25}}[/tex]

[tex]\sin A=\dfrac{4}{5}[/tex]

Now,

[tex]\csc A=\dfrac{1}{\sin A}[/tex]

[tex]\csc A=\dfrac{1}{\frac{4}{5}}[/tex]

[tex]\csc A=\dfrac{5}{4}[/tex]

Thus, the required value is [tex]\csc A=\dfrac{5}{4}[/tex].

The required value of cscA is 1.25

Given,

Trigonometrical ratios:

In the first quadrant, all ratios are positives.

[tex]sin A=\frac{P}{H}[/tex]

And the value of hypotenuse is,

[tex]P=\sqrt{H^2-B^2} \\=\sqrt{5^2-3^2} \\=\sqrt{16}\\ P=4[/tex]

So, the sine A is,

[tex]sinA=\frac{P}{H}\\ =\frac{4}{5}[/tex]

So, the rational denominator is,

[tex]cscA=\frac{H}{P}\\ =\frac{5}{4}\\=1.25[/tex]

Answer:

[tex] y = -\frac{10}{3}x - 23 [/tex]

Step-by-step explanation:

Find slope (m) using of the line that passes through (-9, 7) and (-6, -3).

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-3 - 7}{-6 -(-9)} = \frac{-10}{3} = -\frac{10}{3} [/tex]

Find y-intercept (b) by substituting m = -10/3, x = -6, and y = -3 in y = mx + b.

Thus:

-3 = (-10/3)(-6) + b

-3 = 20 + b

Subtract 20 from each side

-23 = b

b = -23

substitute m = -10/3, and b = -23 in y = mx + b, to get the equation.

The equation of the line would be:

✅ [tex] y = -\frac{10}{3}x + (-23) [/tex]

[tex] y = -\frac{10}{3}x - 23 [/tex]

Answer:

We have 92 % confidence that the true mean time a student sleeps per night is between (-0.25, 1.61).

Step-by-step explanation:

Compute the sample mean and sample standard deviation as follows:

[tex]\bar x=\frac{1}{n}\sum X=\frac{54.3 }{8}=6.788\\\\s=\sqrt{\frac{1}{n-1}\sum (x-\bar x)^{2}}=\sqrt{\frac{1}{8-1}\times 11.8288}=1.299[/tex]

Since, the sample standard deviation is computed the t-statistics will be used for the confidence interval.

The critical value of t for (n - 1) degrees of freedom and 92% confidence level is:

[tex]t_{\alpha/2, (n-1)}=t_{0.04, 7}=2.046[/tex]

*Use a t-table.

Compute the 92% confidence interval for the true mean time a student sleeps per night as follows:

[tex]CI=\bar x\pm t_{\alpha/2, (n-1)}\cdot\frac{s}{\sqrt{n}}[/tex]

     [tex]=6.788\pm 2.046\times\frac{1.299}{\sqrt{8}}\\\\=6.788\pm 0.9392\\\\=(-0.2504, 1.6080)\\\\\approx (-0.25, 1.61)[/tex]

We have 92 % confidence that the true mean time a student sleeps per night is between (-0.25, 1.61).

Answer:I believe left

Step-by-step explanation:

Answer:

a. See explanation for table

b. The 7th hour

Step-by-step explanation:

Given

Ski Resort

[tex]Base\ Snow = 75in[/tex]

[tex]Rate = 1in[/tex] hourly

Mt. Winterpark

[tex]Base\ Snow = 68in[/tex]

[tex]Rate = 2in[/tex] hourly

First, we need to illustrate the amount of snow as an equation in both cases.

[tex]Amount = Base\ Snow + Rate * Time[/tex]

Let x be number of hours. and y be the amount of snow

So:

Ski Resort

[tex]y= 75 + 1* x[/tex]

[tex]y= 75 + x[/tex]

Mt. Winterpark

[tex]y= 68 + 2 * x[/tex]

[tex]y= 68 + 2x[/tex]

Next, we make a table to show the data.

When [tex]x = 0[/tex]

Ski Resort: [tex]y = 75 + 0 = 75[/tex]

Mt. Winterpark: [tex]y = 68 + 2(0) = 68[/tex]

When [tex]x = 1[/tex]

Ski Resort: [tex]y = 75 + 1 = 76[/tex]

Mt. Winterpark: [tex]y = 68 + 2(1) = 70[/tex]

When [tex]x = 2[/tex]

Ski Resort: [tex]y = 75 + 2 = 77[/tex]

Mt. Winterpark: [tex]y = 68 + 2(2) = 72[/tex]

When [tex]x = 3[/tex]

Ski Resort: [tex]y = 75 + 3 = 78[/tex]

Mt. Winterpark: [tex]y = 68 + 2(3) = 74[/tex]

When [tex]x = 4[/tex]

Ski Resort: [tex]y = 75 + 4 = 79[/tex]

Mt. Winterpark: [tex]y = 68 + 2(4) = 76[/tex]

When [tex]x = 5[/tex]

Ski Resort: [tex]y = 75 + 5 = 80[/tex]

Mt. Winterpark: [tex]y = 68 + 2(5) = 78[/tex]

When [tex]x = 6[/tex]

Ski Resort: [tex]y = 75 + 6 = 81[/tex]

Mt. Winterpark: [tex]y = 68 + 2(6) = 80[/tex]

When [tex]x = 7[/tex]

Ski Resort: [tex]y = 75 + 7 = 82[/tex]

Mt. Winterpark: [tex]y = 68 + 2(7) = 82[/tex]

When [tex]x = 8[/tex]

Ski Resort: [tex]y = 75 + 8 = 83[/tex]

Mt. Winterpark: [tex]y = 68 + 2(8) = 84[/tex]

When [tex]x = 9[/tex]

Ski Resort: [tex]y = 75 + 9 = 84[/tex]

Mt. Winterpark: [tex]y = 68 + 2(9) = 86[/tex]

When [tex]x = 10[/tex]

Ski Resort: [tex]y = 75 + 10 = 85[/tex]

Mt. Winterpark: [tex]y = 68 + 2(10) = 88[/tex]

Hence, the table is:

x ---- Ski Resort ---- Mt. Winterpark

0 --------75 ----------- 68

1 --------76 ----------- 70

2 --------77 ----------- 72

3 --------78 ----------- 74

4 --------79 ----------- 76

5 --------80 ----------- 78

6 --------81 ----------- 80

7 --------82 ----------- 82

8 --------83 ----------- 84

9 --------84 ----------- 86

10 -------85 ----------- 88

(b)

From the table, the amount of snow is the same at the 7th hour and the snow is 82 inches
