a) Factor 9x² + y² + z² - 6xy + 2yz - 6xz

This looks a lot like

(x+y+z)² = x² + y² + z²+ 2xy + 2yz + 2xz

except instead of x there's (-3x).   So this must be

(-3x+y+z)² = (-3x)² + y² + z² + 2((-3x)y + (-3x)z + yz)

= 9x² + y² + z² - 6xy + 2yz - 6xz

Looks good.

Answer: (-3x+y+z)²

Since it's a square we could also negate the inside and write this (3x-y-z)²

b) I'll guess that says we want to evaluate this when x=1, y=2, z= -1

(-3(1) + 2 -1)² = (-2)² = 4

Answer:

The yield is 5.974%

Step-by-step explanation:

We proceed as follows ;

coupon rate = Annual coupon payment/bond face value.

The face value is the original amount which the bond was bought and that is $515 according to the question. While the coupon rate is 5.8%

mathematically, annual coupon payment = coupon rate * bond face value = 0.058 * 515 = $29.87

mathematically;

current yield = Annual coupon payment/bond price

current yield = 29.87/500

= 0.05974 or simply 5.974%

so the answer is c. 5.6%

Step-by-step explanation:

Answer:

A 6.0%

Step-by-step explanation:

coupon rate = Annual coupon payment/bond face value.

The face value is the original amount which the bond was bought and that is $515 according to the question. While the coupon rate is 5.8%

mathematically, annual coupon payment = coupon rate * bond face value = 0.058 * 515 = $29.87

mathematically;

current yield = Annual coupon payment/bond price

current yield = 29.87/500

= 0.05974 or simply 5.974%

5.974 rounded to 6.0 %

304,305,306

Step-by-step explanation:

x +x+1+x+2=915

3x+3=915

3x=915-3

3x=912

x=304

The three consecutive integers are 304, 305 and 306, option D is correct.

A number system is defined as a system of writing to express numbers.

Let the three consecutive numbers be x, x+1 and x+2

Sum of three consecutive integers is 915.

x+x+1+x+2=915

3x+3=915

Subtract 3 on both sides

3x=912

Divide both sides by 3

x=304

Hence, the three consecutive integers are 304, 305 and 306, option D is correct.

Answer:

[tex]A = \dfrac{C^2}{4\pi}[/tex]

Step-by-step explanation:

Given that

Area of a circle [tex]A=\pi r^2[/tex]

Circumference of the circle [tex]C = 2 \pi r[/tex]

Let us re-write the equation of area of circle:

[tex]A=\pi r^2[/tex]

[tex]A = \pi \times r \times r[/tex]

Multiplying and dividing with 2:

[tex]A = \dfrac{2\pi r}{2} \times r\\\text{Putting }2\pi r = C:\\\Rightarrow A = \dfrac{C}{2} \times r\\\text{Multiplying and dividing by } 2\pi:\\\Rightarrow A = \dfrac{C}{2} \times \dfrac{2\pi r}{2\pi}\\\text{Putting }2\pi r = C:\\\Rightarrow A = \dfrac{C \times C}{4 \pi}\\\Rightarrow A = \dfrac{C^2}{4 \pi}[/tex]

Hence, A in terms of C can be represented as:

[tex]A = \dfrac{C^2}{4\pi}[/tex]

Answer:

Angle A: 40°

Angle B: 50°

Angle C: 90°

Side A: 14

Side B: 12

Side C: 11.2 or 11 if you round to the nearest whole number.

Step-by-step explanation:

Angle A;

Since we know angles B and C we can use those to help us find angle since all three angles should add up to 180°.

90-50=40

Angle A= 40°

Side C;

Since we know all the angles now and the other two side lengths, we will use those to help us find Side C.

cos 40°= C/14

C/14= cos 40°

C/14=  .8

C= .8 x 14

C= 11.2

Answer:

x = 2

Step-by-step explanation:

h(x) = f(x) + g(x) = x³ + 2x² + 1 - x³ - x² - 4x + 4 ← collect like terms, thus

h(x) = f(x) + g(x) = x² - 4x + 5

Given

h(x) = 1, then

x² - 4x + 5 = 1 ( subtract 1 from both sides )

x² - 4x + 4 = 0 ← in standard form

(x - 2)² = 0 ← in factored form ( perfect square ), thus

x - 2 = 0 ⇒ x = 2

Step-by-step explanation:

Solution 1.

Alex has $40, and Ellen has $24. Alex is saving $6 per day, and Ellen is saving $10 day.

Let x be the number of days in which they both have same money:

As per given statement:

[tex]40 + 6x=24+10x\\\Rightarrow 4x = 16\\\Rightarrow x =4[/tex]

In 4 days, they will have same money.

Solution 2:

Kendra owns a restaurant. She charges $6.00 for two eggs and one piece of toast and $3.60 for one egg and one piece of toast.

Let x be the price of one egg.

Let y be the price of one toast.

As per given statement:

[tex]2x+y=6 ...... (1)\\x+y= 3.6 ...... (2)[/tex]

Subtracting (2) from (1):

[tex]\Rightarrow x = \$2.4[/tex]

Price of toast = 3.6 - 2.4 = $1.2

Solution 3:

A restaurant has one type of lemonade that is 30% sugar and another that is 10% sugar. Resultant mixture 4 gallons of 15% sugar.

Let x be the amount of lemonade with 30% sugar.

Amount of another lemonade with 10% sugar = (4-x)

As per question statement:

[tex]x \times 30\% + (4-x) \times 10\% = 4 \times 15\%\\\Rightarrow x \times 30 + (4-x) \times 10 = 4 \times 15\\\Rightarrow 20x = 20\\\Rightarrow x = 1[/tex]

Lemonade with 30% sugar required is 1 gallon.

Lemonade with 10% sugar required is 3 gallons.

Solution 4:

A scientist has a container of 2% acid solution and a container of 5% acid solution. Resultant mixture is 25 fl oz of 3.2%.

Let x be the amount of 2% acid solution.

Amount of another lemonade with 5% acid solution = (25-x)

As per given question statement:

[tex]2\%\ of\ x + 5\% \ of\ (25-x) = 3.2\%\ of\ 25\\\Rightarrow 2x + 5(25-x)=3.2 \times 25\\\Rightarrow -3x = -1.8 \times 25\\\Rightarrow x = 15[/tex]

2% acid solution required is 15 fl oz.

5% acid solution required is 10 fl oz.

Answer: 6 cm

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:  

Volume of a cylinder (V): π x radius ² x height  

Replacing with the values given and solving for v (Volume)  

1584 = π x r ² x 14

Solving for r:

1584 / (π x 14) = r²

36.01 = r²

√36.01 = r

6 cm = r

In conclusion, the radius of the cylinder is 6 centimeters.

Feel free to ask for more if needed or if you did not understand something.

Answer:

The radius is 6 cm

Step-by-step explanation:

To solve this, we will follow the steps below:

write down the formula for finding the volume of a cylinder

volume of a cylinder =πr²h

from the question volume of the cylinder = 1584 cm²

height = 14 cm

substitute the formula and solve for r

π is a constant and is ≈ 3.14

1584 = 3.14×r²×14

1584= 43.96 r²

divide both-side of the equation by 43.96

36≈ r²

take the square root of both-side

√36 = √r²

6 = r

r = 6cm

The radius is 6 cm

Answer:

The base of the rhombus is equal to 9 centimeters.

Step-by-step explanation:

To calculate the base of the rhombus, we will follow the steps below;

write the formula for calculating the area of a rhombus

area of a rhombus = b × h

where h is the height of the rhombus and b is the base of the rhombus

From the question given,  area of the rhombus = 72 square centimeters   and height of the rhombus is 8 centimeters.

we can now proceed to insert the values into the formula and then solve for b

area of a rhombus = b × h

                72          = b × 8

Divide both-side of the equation by 8

[tex]\frac{72}{8}[/tex]  =  b × 8 /8

[tex]\frac{72}{8}[/tex]   =   b

9 = b

b = 9 centimeters

The base of the rhombus is equal to 9 centimeters.

Hope it helps
