If h(x)=6-x, what is the value of (h o h)(10)

Answer-

In picture 4, the triangle is reflected over x axis.

Solution-

While reflecting a point over x axis, (x, y) → (x, -y) rule is followed.

Only the sign of y-coordinate is changed, keeping x-coordinate intact.

In the first picture, though the image is reflected, but it is reflected over y axis.

In the second picture, the image is first reflected over y axis, then it is translated 1 unit down.

We rotating a point 90° clockwise, (x, y) → (y. -x) rule is followed.

In the third picture, the triangle is rotated 90° clockwise and then translated 1 unit to right.

But, in case of the fourth picture, the figure is reflected over x axis. Only the y coordinates sign are changed, all the x coordinates are same as before.

The required pair of number are -3 and -6

The factored form of the trinomial is (x-3) and (x-6)

The standard form of a quadratic equation is expressed as:

[tex]ax^2+bx+c=0[/tex]

Given the expression [tex]x^2 - 9x + 18.[/tex]

[tex]a=1\\b=-9\\c=18[/tex]

We are to get two values that we must add to get b, and that we will multiply that will give c.

The given values are -6 and -3

Check:

[tex]-6+(-3)=-6-3=-9\\-6(-3) = 18[/tex]

Factorize the trinomial

[tex]x^2-9x+18\\x^2-6x-3x+18\\x(x-6)-3(x-6)\\(x-3)(x-6)[/tex]

Hence the factored form of the trinomial is (x-3) and (x-6).

Answer:

The correct option is D.

Step-by-step explanation:

The given expression is

[tex]36x^2-49[/tex]

It can be written as

[tex](6x)^2-(7)^2[/tex]

Using the formula

[tex]a^2-b^2=(a-b)(a+b)[/tex]

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

Therefore the complete factor form of given expression is (6x+7)(6x-7). The correct option is D.

To isolate the variable in x + 5 = -12, subtract 5 from both sides of the equation. This leads to the equation x = -12 - 5.

In order to isolate the variable x in the equation x + 5 = -12, you should subtract 5 from both sides of the equation. This gives us the equation in a simplified form that allows us to determine the value of x. The idea here is to cancel out the +5 on the left side by subtracting 5 from both sides, resulting in x = -12 - 5. Hence, the answer is option b.

The variables in this situation are the price of the tickets and the quantity of tickets sold. The relationship between price, quantity, and revenue can be analyzed using the concept of price elasticity of demand. Diana should lower the price if demand is elastic, raise the price if demand is inelastic, and can maintain the same revenue if demand has unitary elasticity.

The variables in this situation are the price of the tickets and the quantity of tickets sold. These two variables directly affect the total revenue generated by Diana from ticket sales. The relationship between price, quantity, and revenue can be analyzed using the concept of price elasticity of demand.

If demand for tickets is elastic, Diana should lower the price to increase total revenue. A decrease in price will result in a larger percentage increase in the quantity sold, leading to a higher total revenue. On the other hand, if demand is inelastic, Diana should raise the price to increase revenue. A certain percentage increase in price will result in a smaller percentage decrease in quantity sold, ultimately raising total revenue.

If demand has unitary elasticity, an equal percentage change in quantity will offset a moderate percentage change in price. In this case, Diana can earn the same revenue regardless of a moderate increase or decrease in ticket price.

Answer:

The rectangular equation that is equivalent to the given polar equation is:

y= -2

Step-by-step explanation:

We know that the polar coordinate of a equation are related to the rectangular coordinates of the equation as:

[tex]x=r\sin \theta\\\\y=r\cos \theta[/tex]

where,

[tex]r=\sqrt{x^2+y^2}[/tex]

Now we are given that:

[tex]r\sin \theta=-2[/tex]

Also,

[tex]\theta=\arctan \dfrac{y}{x}[/tex]

Hence, on converting the given polar equation to the rectangular equation we get:

[tex]y=-2[/tex]

A scale model of a school building is 5 inches tall.

Actual size of the school building is 100 feet.

1 feet=12 inches

100 feet=12×100 inches

             = 1200 inches

5 inch is representing 1200 inches

1 inch represents  1200/5 inches

1 inch represents  240 inches

or  1 inch represents  12×20 inch

or 1 inch represents 20 feet

Scale of the model is:

1 inch represents  240 inches

1 inch represents 20 feet

The probability that the first number is a 3 and the second is a 7 is 1/64

It is a branch of mathematics that deals with the occurrence of a random event.

Given:

spinner had region numbered from 1 to 8

So, the probability on the spinner has an equally likely chance of being selected= 1/8.

P(3) = 1/8

P(7) = 1/8

Thus, probability that the first number is a 3 and the second is a 7

=(1/8) * (1/8)

= 1/64

Answer:

The answer is D.

Step-by-step explanation:

We know this because it is an "and" problem because it is numbers in between, not outside.

We also know it is "no less" or "no more" than 50 or 100. so we use a less than and equal too. Not just a less than sign.

Really hoped this helped, kind of in a test right now so just giving a brief way of how to figure this stuff out.

The correct answer is: c. II and III only

To determine which volume formula(s) exhibit joint variation, we need to consider if the volume (V) varies directly with two or more variables. In joint variation, V is directly proportional to the product of two or more variables.

Let's analyze each formula:

I. V = 8^3 → This is not a joint variation as V is solely dependent on the constant 8.

II. V = πr^2h → This shows joint variation as V varies directly with both r and h.

III. V = Bh → This also exhibits joint variation since V varies directly with both B (base area) and h (height).

Answer:

negative 5 plus or minus the square root of 17 divided by two: [tex]x=\frac{-5\pm\sqrt{17}}{2}[/tex].

Step-by-step explanation:

We have the equation

[tex]x^2+5x=-2[/tex]

[tex]x^2+5x+2=0[/tex].

To solve it, we are going to use the general formula. This formula is used to find the solutions of quadratic equations.

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

where a is the coefficient of [tex]x^2[/tex], in this case a=1, b is the coefficient of x, in this case b=5 and c is the independent term, in this case c=2.

[tex]x=\frac{-5\pm\sqrt{5^2-4(1)(2)}}{2(1)}[/tex]

[tex]x=\frac{-5\pm\sqrt{25-8}}{2}[/tex]

Fiona should use 1 cup of butter when using 3 cups of flour, according to the recipe's ratio of 24:8:3 for flour to butter to water.

The question asks how much butter Fiona should use if she's using 3 cups of flour and the recipe calls for flour, butter, and water in the ratio of 24:8:3. To solve this, we take the ratio for butter (which is 8) and divide it by the flour ratio (which is 24), then multiply by the number of cups of flour Fiona is using (which is 3 cups).
