or

10.55 if question is [tex]3.5^2 - \sqrt{8} \cdot 6[/tex]

(see explanation below)

Step-by-step explanation:

I took the question as
[tex]3.5^2-\sqrt{8.6}[/tex]

since it was not clear if it was [tex]\sqrt{8.6}[/tex] or [tex]\sqrt{8} \cdot 6[/tex]

If it is  [tex]3.5^2 - \sqrt{8} \cdot 6[/tex] then the answer would be 10.55

Answer:

a = - 2

Step-by-step explanation:

since the point (3, 2 ) lies on the parabola, then it makes the equation true.

substitute x = 3, y = 2 into the equation and solve for a

y = ax² + 3x + 11

2 = a(3)² + 3(3) + 11

2 = 9a + 9 + 11

2 = 9a + 20 ( subtract 20 from both sides )

- 18 = 9a ( divide both sides by 9 )

- 2 = a

Answer:

a = -2

Step-by-step explanation:

Given quadratic equation:

[tex]y=ax^2+3x+11[/tex]

In order to find "a", substitute the given point on the curve (3, 2) into the equation and solve for a:

[tex]\begin{aligned}y&=ax^2+3x+11\\\textsf{Substitute $(3,2)$} \implies 2&=a(3)^2+3(3)+11\\2&=9a+9+11\\2&=9a+20\\2-20&=9a+20-20\\-18&=9a\\9a&=-18\\\dfrac{9a}{9}&=\dfrac{-18}{9}\\\implies a&=-2 \end{aligned}[/tex]

Therefore, the value of "a" so that parabola y = ax² + 3x + 11 goes through the point (3, 2) is:

[tex]\large \boxed{a=-2}[/tex]

The expression of b over negative 5.6 is less than or equal to negative 4.9 for b ≤ 0.7 ( b less than or equal to 0.7 ).

Based on the given conditions,

Negative 5.6 means = -5.6

Negative 4.9 means = -4.9

Negative 5.6 means ≤ Negative 4.9 means

Then,

-5.6  ≤  -4.9

But,

Let the number b is over negative 5.6,

It means,

We can write,

b + (-5.6)      (Equation-1)

This equation-1 is write into,

b + (-5.6) ≤  -4.9

b - 5.6 ≤  -4.9

b ≤ (-4.9) + 5.6

We can sum or difference the products,

b ≤ 0.7

Therefore,

The expression b over negative 5.6 is less than or equal to negative 4.9 for b ≤ 0.7

The following linear equation gives Johnny's savings w weeks after her opened the account.

S(w) = $95 + $15*w

We know that initially, Johnny deposits an amount of $95, and then he saves $15 per week.

So, after w weeks, the amount in that savings account will be:

S(w) = $95 + $15*w

This linear equation gives the bank account balance w weeks after her opened the account.

The probability is 5/8

Step-by-step explanation:

This how we change 23 out of 25 to a percentage

The numerator of a question is the number that appears above the bar; in this case, the numerator is 23.

The denominator is the number beneath the bar, and in this question, it is 25.

To calculate the value of a fraction, divide the numerator by the denominator.

Therefore, we must divide 23 by 25.

23/25 = 0.92

To determine the percentage, multiply the outcome by 100.

The percentage value will be obtained by multiplying 0.92 by 100.

0.92 x 100 = 92%

As a result, 92% is the answer to the question.

The measures of the unknown angles are as follows:

The measures of each angles can be found as follows:

Therefore,

∠AEB = ∠CED (vertically opposite angle)

∠DEA = ∠BEC (vertically opposite angle)

Vertically opposite angles are equal.

Therefore,

4x = 75 - x

4x + x = 75

5x = 75

x = 75 / 5

x = 15

Therefore,

∠DEA = ∠BEC = 4(15) = 60°

Proved [tex]Cos^{4}x - Sin^{4}x + 1[/tex] = 2Cos²x

We will use the Pythagorean Theorem:

Sin²x + Cos²x = 1

from which we can get:

Sin²x = 1 - Cos²x

Also, note that the difference in the similarity of squares can be written:

A² - B² = (A - B)

We can use this with A = Sin²x and B = Cos²x as follows:

[tex]Sin^{4}x - Cos^{4}x[/tex]

= (Sin²x)² - (Cos²x)²

= (Sin²x - Cos²x) (Sin²x + Cos²x)

= Sin²x - Cos²x

= (1 - Cos²x) - Cos²x

= 1 - 2Cos²x

Now move the 1 and negative symbols to the left.

[tex]Cos^{4}x - Sin^{4}x + 1[/tex] = 2Cos²x

√134 is the number which is located between 11 and 12 on a number line.

A number line is a horizontal straight line on which real numbers are arranged in equal intervals. This line extends both sides at infinity.

Comparison and operations of numbers can be better explained using number lines.

Taking consecutive perfect squares of integers which lies above and below the given numbers on the number line and taking it's square root, we can find the answer.

The perfect squares below and above 150 are 144 = 12² and 169 = 13². So √150 lies in between 12 and 13.

The perfect squares below and above 134 are 121 = 11² and 144 = 12². So √134 lies in between 11 and 12.

The perfect squares below and above 115 are 100 = 10² and 121 = 11². So √115 lies in between 10 and 11.

The number 121 is itself a perfect square. √121 = 11.

Hence √134 is the number which lies in between 11 and 12.
