Line segment YZ was used to translate ABCDE. YZ is 5.5 inches long.what is the length of AA + BB + CC + DD +EE?

Option: A is the correct answer.

              The axis of symmetry is:

                      A.    x=3/2      

We are given a graph as:

[tex]y+3x-6=-3(x-2)^2+4[/tex]

and

[tex]y=-3(x-2)^2+4+6-3x[/tex]

and

[tex]y=-3[(x-2)^2+x]+10\\\\i.e.\\\\y=-3[x^2+4-4x+x]+10\\\\i.e.\\\\y=-3[x^2-3x+4]+10[/tex]

This equation could also be written in the form:

[tex]y=-3[x^2-3x+4-\dfrac{9}{4}+\dfrac{9}{4}]+10\\\\i.e.\\\\y=-3[(x-\dfrac{3}{2})^2+4-\dfrac{9}{4}]+10\\\\i.e.\\\\y=-3[(x-\dfrac{3}{2})^2+\dfrac{7}{4}]+10\\\\i.e.\\\\y=-3(x-\dfrac{3}{2})^2-3\times \dfrac{7}{4}+10\\\\i.e.\\\\y=-3(x-\dfrac{3}{2})^2+\dfrac{19}{4}[/tex]

Now, we know that for any general equation of the type:

[tex]y=a(x-h)^2+k[/tex]

The axis of symmetry of the graph of the equation is:

[tex]x=h[/tex]

Here we have:

[tex]h=\dfrac{3}{2}[/tex]

Final answer:

To find out how many pounds of untrimmed celery is needed to get 8 pounds of trimmed celery with a 75% yield, we divide the required trimmed weight by the yield percentage as a decimal. The calculation is 8 divided by 0.75, which equals approximately 10.67 pounds of untrimmed celery.

Explanation:

To determine the amount of untrimmed celery needed when a recipe requires 8 pounds of trimmed celery with a 75% yield, we use the yield percentage to find out how much the weight reduces during trimming. Yield percentage tells us how much of the original, or untrimmed, product remains after trimming. In this case, a 75% yield means that 75% of the untrimmed celery's weight will be left after trimming.

To find the amount of untrimmed celery, we set up the equation using the yield percentage (Y) of the untrimmed weight (U) that will result in the desired trimmed weight (T). The equation is T = U * Y/100. We can rearrange the equation to solve for U using the given values. So U = T / (Y/100), which gives us U = 8 / (75/100), resulting in U = 8 / 0.75.

After completing the division, we find that U equals 10.67. This means we need approximately 10.67 pounds of untrimmed celery to get 8 pounds of trimmed celery. Always remember to round according to the context, in most recipes a little more celery wouldn't be a problem, but it depends on the precision needed for the specific recipe.

Step-by-step explanation:

The area of the rectangular rug is given by this equation:

[tex]77r^2-4r-77[/tex]

The area must be a number greater than 0 since a negative area, or an area equal to 0 wouldn't have much sense. So:

[tex]77r^2-4r-77>0[/tex]

Let's find the roots of this equation using the quadratic formula:

[tex]r=\frac{-b\pm \sqrt{b^2-4ac} }{2a} =\frac{-(-4)\pm\sqrt{(-4)^2-(4)(77)(-77)} }{2(77)} \\\\r=\frac{4 \pm \sqrt{23732} }{154} \\\\r_1=\frac{4 +\sqrt{23732} }{154} \approx1.03\\\\r_2=\frac{4 - \sqrt{23732} }{154} \approx-0.97[/tex]

Now, let's evaluate the area for [tex]r>r_1[/tex] for example r=1.05:

[tex]A=77(1.05)^2-4(1.05)-77=3.6925>0[/tex]

The result is greater than zero, so for [tex]r>r_1[/tex] the values make sense.

Now let's evaluate the area for [tex]r_2<r<r_1[/tex] for example r=0.5 and r=-0.7:

[tex]A=77(0.5)^2-4(0.5)-77=-59.75<0\\\\A=77(-0.7)^2-4(-0.7)-77=-36.47<0[/tex]

The result is less than zero, so for [tex]r_2<r<r_1[/tex] the values don't make sense.

Now, let's evaluate the area for [tex]r<r_2[/tex] for example r=-1:

[tex]A=77(-1)^2-4(-1)-77=4>0[/tex]

The result is greater than zero, so for [tex]r<r_2[/tex] the values make sense

However, since negative values of r wouldn't make much sense (I never heard about of -8 inches for example) the possible dimensions of the​ rug are just:

[tex]r>\frac{4 +\sqrt{23732} }{154} \approx1.03\\[/tex]

Answer:

62.1371 miles/hr

Step-by-step explanation:

The posted speed limit in many parts in Europe = 100 kilometers per hour

We have to convert the speed limit into miles per hour.

As we know, 1 kilometer = 0.621371 miles

Therefore, 100 kilometers = 100 × 0.621371

                                           = 62.1371 miles

The equivalent speed of 100 km/hr is 62.1371 miles/hr.

The fish swims 264 yards per minute faster than the boy.

To find out how much faster the fish swims than the boy in yards per minute, we first need to convert both speeds to yards per minute. Since 3 feet is equal to 1 yard, we can convert the fish's speed of 4.4 feet per second to yards per minute by multiplying it by (3 feet/1 yard) × (60 seconds/1 minute) = 4.4 × 3 × 60 yards per minute = 792 yards per minute. Similarly, the boy's speed of 12 miles per hour can be converted to yards per minute by multiplying it by (5280 feet/1 mile) × (1 yard/3 feet) × (1 hour/60 minutes) = 12 × 5280/3/60 yards per minute = 1056 yards per minute.

To find out how much faster the fish swims than the boy, we subtract the boy's speed from the fish's speed: 792 - 1056 = -264 yards per minute. Therefore, the fish swims 264 yards per minute faster than the boy.

The answer is -π

If you add π + (-π), you get 0 which is a rational number.

Adding 2 only results in changing the 3.14... to a 5.14... which is still an irrational number.

Adding 1/π only results in adding 1/3.14... to π which equals 3.45... which is still an irrational number.

Adding 0 doesn't change the original value at all so its still an irrational number.

Therefore, -π is the only logical answer.

Answer: C) mC > mA > mB is correct regarding the angles of the  triangle ABC.

Step-by-step explanation:

Given: In Δ ABC, the side lengths of triangle ABC are written in terms of the variable p, where p ≥ 3.

AB=4p-1 , AC=p+4 , BC=3p

where p+4 < 3p        [as p≥3]

3p < 4p-1          [as p≥3]

⇒  4p-1> 3p > p+4

⇒AB>BC>AC

Angle opposite to AB ,BC and AC is m∠C ,m∠A and m∠B.

Therefore mC > mB > mA    [∵Angle opposite to greater side is greater]

Thus , mC > mA > mB is correct regarding the angles of the  triangle ABC.

Answer:

Step-by-step explanation:

To solve the problem, set up and solve an algebraic equation. Find the value of x, then use it to determine the number of years it will take for you to be twice as old as your brother.

To solve this problem, we can use algebraic equations. Let's assume the age of your brother is x. Since you are four times as old as your brother, your age would be 4x. In two years, your age would be 4x + 2, and your brother's age would be x + 2. According to the problem, 4x + 2 = 3(x + 2). We can solve this equation to find x, and then determine the number of years it will take for you to be twice as old as your brother.

By simplifying the equation, we get 4x + 2 = 3x + 6. Subtracted 3x from both sides, we get x + 2 = 6. Subtracting 2 from both sides, we get x = 4.

So, your brother's age is currently 4 and your age is currently 16. To determine the number of years it will take for you to be twice as old as your brother, we need to find the value of y that satisfies the equation 2(4 + y) = 16 + y. By solving this equation, we'll find that it will take 8 years for you to be twice as old as your brother.

Answer:

The decay factor is 0.88.

Step-by-step explanation:

The general form of an exponential decay function is

[tex]f(x)=ab^x[/tex]

Where, a is initial value and b is decay factor.

It is given a new truck that sells for $29,000 depreciates (decreases in value) 12% each year.

The initial value is $29,000 and decay factor is

[tex]1-r=1-\frac{12}{100}=1-0.12=0.88[/tex]

The exponential function is

[tex]f(x)=29000(0.88)^x[/tex]

Therefore the decay factor is 0.88.

The decay factor b for the truck, which depreciates 12% each year, is 0.88.

The decay factor, b, for the truck's depreciation can be calculated using the formula for exponential decay:

b = 1 - r

where r is the annual depreciation rate. In this case, the annual depreciation rate is given as 12%, or 0.12 in decimal form.

Now, let's calculate the decay factor:

b = 1 - 0.12

b = 0.88

So, the decay factor for the truck's depreciation is 0.88.

The decay factor is used to calculate the value of the truck after n years by raising b to the power of n and multiplying it by the initial value of the truck. The formula for the value of the truck after n years is:

[tex]\[ V(n) = P \cdot b^n \][/tex]

where P is the initial price of the truck, b is the decay factor, and n is the number of years.

In this case, the initial price P is $29,000, and the decay factor b is 0.88. If we want to find the value of the truck after, say, 5 years, we would use the formula:

[tex]\[ V(5) = 29000 \cdot (0.88)^5 \][/tex]

However, the question only asks for the decay factor, which we have already determined to be 0.88.

Answer:
