ask a teacher if needed

Answer:

Step-by-step explanation:

well all you have to do is 500 dollars times two, because it times each 15 years right and 30/15=2. So you do $500*2 which is $1000. And you get $1500 in 45 yrs.

So the equations are for each 15 yrs you add 500 dollars to the amount.

Answer:

$66,378.

Step-by-step explanation:

Average salary for the last 5 years = (93000+94000+98000+94000+102000)

/ 5

= $96,200

So his pension = 96,000 * 0.023 * 30

= $66,378.

Answer: 80

Step-by-step explanation:

Sin x = cos (90-x)

Like sin 30 = cos (90-30) =cos 60

So

90-x=90-80

Then

X=80

Verify your solution by finding the sum of the angles of sin and cos, it will be 90

Answer:

Step-by-step explanation:

Sin Ф = Cos (90 - Ф)

Comparing with this

Sin 80 = Cos (90 - 80) = Cos 10

So, x = 80

Answer:

Pizza: 27°

Curry: 108°

Fish and Chips: 63°

Kabab: 27°

Other: 135°

Step-by-step explanation:

Frequency 40 = 360°

Pizza (3) = [tex]\frac{3}{40}[/tex] * 360° = 27°

Curry (12) = [tex]\frac{12}{40}[/tex] * 360° = 108°

Fish and Chips (7) = [tex]\frac{7}{40}[/tex] * 360° = 63°

Kabab (3) = [tex]\frac{3}{40}[/tex] * 360° = 27°

Other (15) = [tex]\frac{15}{40}[/tex] * 360° = 135°

27 + 108 + 63 + 27 + 135 = 360

Answer:

D, 34,000 milliliters

Step-by-step explanation:

There are 1,000 milliliters in a liter. So, if we had 1 liter, we would have 1*1,000=1,000 milliliters.

When you change the 1 liter to 34, we can just substitute 34 for 1. So, the answer is 34*1,000=34,000 milliliters, or D

Answer:

k^2-8k+12=0D

Step-by-step explanation:

Explanation:

1) Given equation:

         k+12/k=8

2) Multiplication property of equality:

        k(k+12/k)=8k

3) Distributive property:

        k^2+12k/k=8k

4) Simplification:

        k^2+12=8k

5) Subtraction property of equality:

        k^2-8k+12=0

Answer:

k^2-8k+12=0D is correct

Step-by-step explanation:

Answer:

y = - 2(x - 2)² - 3

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (2, - 3) , thus

y = a(x - 2)² - 3

To find a substitute (1, - 5) a point on the curve into the equation

- 5 = a(1 - 2)² - 3

- 5 = a - 3 ⇒ a = - 5 + 3 = - 2

y = - 2(x - 2)² - 3 ← equation in vertex form

Answer:

x = 5  (Answer C)

Step-by-step explanation:

Set f(x) = 3x - 15 = to 0 and solve for x:

3x - 15 =  0

Adding 15 to both sides isolates 3x:

3x = 15

Dividing both sides by 3 yields x = 5  (Answer C)

Mixed fractions are a fraction that represents their quotient and remainder. It is a type of fraction in which the whole number part and fractional part is present.

At first, we have to find the common denominator LCD [tex]=11*5=55[/tex];

Now, [tex]\frac{36}{11}=\frac{180}{55}[/tex]  and [tex]\frac{17}{5}=\frac{187}{55}[/tex]

So, from above we get;

[tex]\frac{181}{55} , \frac{182}{55},\frac{183}{55}, \frac{184}{55} ,\frac{185}{55} ,\frac{186}{55}[/tex] as mixed fractions between given mixed fractions.

Again, we will multiply both denominator and numerator by 2, and we get;

[tex]\frac{180}{55}=\frac{360}{110}[/tex]  and [tex]\frac{187}{55} =\frac{374}{110}[/tex]

So, repeating the same step, we get;

[tex]\frac{361}{110},\frac{362}{110} ,\frac{363}{110} ,\frac{364}{110} ,\frac{365}{110},\frac{366}{110} ,\frac{367}{110} ,\frac{368}{110},\frac{369}{110} ,\frac{370}{110} ,\frac{371}{110} ,\frac{372}{110} ,\frac{373}{110}[/tex] are mixed fractions

between given mixed fractions.

A fraction represented with its quotient and remainder is a mixed fraction. For example, 2 1/3 is a mixed fraction, where 2 is the quotient, 1 is the remainder. So, a mixed fraction is a combination of a whole number and a proper fraction

A mixed fraction is one whose value is always greater than 1 and it has a whole number part and a proper fraction. For example, 325 3 2 5 is a mixed number. An improper fraction is one in which the numerator is always greater than or equal to the denominator.

Step-by-step explanation:

Answer:

9 and 11

Step-by-step explanation:

The sum of the squares of two consecutive positive odd integers is 202.

Let first number be x and other number is (x+2).

According to question,

[tex]x^2+(x+2)^2=202\\\\x^2+x^2+4+4x=202\\\\2x^2+4x+4=202\\\\2x^2+4x-198=0[/tex]

It is a quadratic equation. The solution of a quadratic equation is given by :

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

We have, a = 2, b = 4 and c = -198

So,

[tex]x=\dfrac{-b+ \sqrt{b^2-4ac} }{2a}, \dfrac{-b- \sqrt{b^2-4ac} }{2a}\\\\x=\dfrac{-4+ \sqrt{4^2-4\times 2\times (-198)} }{2(2)}, \dfrac{-b- \sqrt{b^2-4ac} }{2a}\\\\x=9, -11[/tex]

So, first positive odd integer is 9 and second one is (9+2)=11

Step-by-step explanation:

We need to write the function that have two real number zeros by calculating the discriminant i.e. [tex]b^2-4ac[/tex].

We know that,

If D>0  the roots are real and unequal

If D= 0 roots are real and equal

If D< 0 roots are imaginary or not real and unequal

Function (1)

[tex]f(x)=x^2 + 6x + 8\\\\D=6^2-4\times 1\times 8\\\\D=4[/tex]

D>0  the roots are real and unequal

Function (2)

[tex]g(x)=x^2 + 4x + 8\\\\D=4^2-4\times 1\times 8\\\\D=-16[/tex]

D<0  the roots are real and unequal

Function (3)

[tex]h(x)=x^2 -12x+32\\\\D=(-12)^2-4\times 1\times 32\\\\D=16[/tex]

D>0  the roots are real and unequal

Function (4)

[tex]k(x)=x^2 +4x-1\\\\D=(4)^2-4\times 1\times (-1)\\\\D=20[/tex]

D>0  the roots are real and unequal

Function (5)

[tex]p(x)=5x^2 +5x+4\\\\D=(5)^2-4\times 5\times 4\\\\D=-55[/tex]

D<0  the roots are real and unequal

Function (6)

[tex]t(x)=x^2 -2x-15\\\\D=(-2)^2-4\times 1\times (-15)\\\\D=64[/tex]

D>0  the roots are real and unequal

(1),(3),(4) and (6) have two real number zeroes.
