The creek by my house is usually 8 feet deep and my house is on a little hill 5 feet above it. They say that if the creek floods 5 feet my house will be destroyed. In a heavy rain the creek rises at a rate of one inch per minute. For the past half hour we have had a heavy rain but now we are in a severe thunderstorm! How Many minutes do my family and i have to evacuate before your home gets destroyed? Inequality Question

Answer:

your answer is 8/40 but is reduced to 1/5

Step-by-step explanation:

Answer:

f(x) = 3x-8

Step-by-step explanation:

y −4 = 3 (x − 4)

We want to write the equation in y = mx+ b form

Distribute the 3

y-4 = 3x -3*4

y-4 = 3x -12

Add 4 to each side

y -4+4 = 3x-12+4

y = 3x-8

Since the want it in function form,  f(x)

f(x) = 3x-8

None of these questions have anything to do directly with the polynomial remainder theorem. The theorem says that the remainder upon dividing a polynomial [tex]p(x)[/tex] by [tex]x-c[/tex] is given by the value of [tex]f(c)[/tex].

For these questions, all you really have to do is evaluate the given polynomials at the given points, and IMO is much less work.

Question 2: [tex]f(5)=4(5)^2-5(5)+2=77[/tex]

Question 3: [tex]f(4)=3(4)^4-8)4)^2-2(4)+12=644[/tex]

Question 4: Here you have check the value of [tex]h(x)[/tex] and 2 and -2, then interpret them as points in the coordinate plane, [tex](x,h(x))[/tex].

[tex]h(-2)=2(-2)^5-4(-2)^4-2(-2)^2+15=-121[/tex]

[tex]h(2)=2(2)^5-4(2)^4-2(2)^2+15=7[/tex]

Question 5: Same as in question 4, but you have to check [tex]h(x)[/tex] at -4, -3, -2, -1.

[tex]h(-4)=72[/tex]

[tex]h(-3)=46[/tex]

[tex]h(-2)=26[/tex]

[tex]h(-1)=12[/tex]

- - -

If you insist on using the polynomial remainder theorem, it's a question of polynomial division. For instance, in question 2 you'd compute

[tex]\dfrac{4x^2-5x+2}{x-5}=4x+15+\dfrac{77}{x-5}\implies4x^2-5x+2=(4x+15)(x-5)+77[/tex]

so the remainder is 77, as we found by simply computing [tex]f(5)[/tex].

Answer:

y + g = 12 ,2y + 3g = 16

y =12-g

Substitute y =12-g in the equation 2y + 3g = 16.

2(12-g)+ 3g = 16

24-2g+3g=16

24+g=16

g=16-24

g= -8

Substitute g= -8 in the equation y =12-g.

y =12-(-8)

=12+8

y =20

Step-by-step explanation:

The value of variable y is 20 and value of variable g is -8.

Two or more expressions with an Equal sign is called as Equation.

The given system of equations are  y+ g = 12 and 2y + 3g = 16

y+g=12

y=12-g...(1)

2y+3g=16..(2)

Substitute 1 in equation 2

2(12-g)+3g=16

24-2g+3g=16

Add the like terms

24+g=16

g=16-24

g=-8

Now substitute the g value in equation y+g=12

y-8=12

Add 8 on both sides

y=20

Hence, the value of variable y is 20 and value of variable g is -8.

Answer:

C

Step-by-step explanation:

using the cosine ratio to find p

cos 45° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{6}{p}[/tex]

cross- multiplying gives

p × cos45° = 6 → [ cos 45° = [tex]\frac{1}{\sqrt{2} }[/tex]]

p × [tex]\frac{1}{\sqrt{2} }[/tex] = 6

multiply both sides by [tex]\sqrt{2}[/tex]

⇒ p = 6[tex]\sqrt{2}[/tex] ( third option on list )

To determine the value of p in simplest radical form, solve the equation by simplifying the denominator and taking the square root of both sides. The value of p is 2.

To identify the value of p, we need to solve the equation and simplify it to the simplest radical form. Let's start by simplifying the denominator and expressing it as a perfect square.

Next, we can take the square root of both sides of the equation to eliminate the square. This will help us isolate p. Once we do that, we can solve for p by getting rid of the square root on the left side of the equation. After simplifying, we find that p = 2.

So, the value of p is 2.

Step-by-step explanation:

In all parts for the quadratic equation [tex]ax^2+bx+c=0[/tex] use Vieta's formulas

[tex]x_1+x_2=-\dfrac{b}{a},\\ \\x_1\cdot x_2=\dfrac{c}{a},[/tex]

where [tex]x_1,\ x_2[/tex] are the roots of the quadratic equation.

A. For the equation [tex]x^2-5x-4=0,[/tex]

[tex]x_1+x_2=5,\\ \\x_1\cdot x_2=-4.[/tex]

Then

[tex](x_1+x_2)^2=x_1^2+2x_1\cdot x_2+x_2^2,\\ \\5^2=x_1^2+x_2^2+2\cdot (-4),\\ \\x_1^2+x_2^2=25+8=33.[/tex]

B. One of the roots of [tex]x^2+12x+k=0[/tex] is twice the other root, then [tex]x_2=2x_1.[/tex] By the Vieta's formulas,

[tex]x_1+x_2=3x_1=-12,\\ \\x_1\cdot x_2=2x_1^2=k.[/tex]

Let's solve each part of the problem step-by-step:

A. First, find the roots of the quadratic equation using Vieta's formulas:

Now, the sum of the squares of the roots is given by: (α² + β²) = (α + β)² - 2αβ. Substituting the known values:
Hence, α² + β² = 25 - (-8) = 25 + 8 = 33.

5x-5x+3y=7-5x

0x+3y=-5x+7

3y=-5x+7

Answer:

Step-by-step explanation:

(a) The given numbers can be put directly into the form ...

Here, we have an intial value of $100, and a ratio of $184.50/$100 = 1.845. The time to achieve that multiplication is 10 years (1967 to 1977). So, the equation can be written ...

Final answer:

Using the provided CPI data, an exponential function is found to model the change in cost of goods over time. The estimated cost of the same goods in 2005, using this model, is approximately $1019.03, illustrating changes in purchasing power and the cost of living.

Explanation:

The question involves finding an exponential function to model the Consumer Price Index (CPI) data and estimate the cost of goods in a future year based on past data. The data provided includes the cost of the same goods being $100 in 1967 (t=0) and $184.50 in 1977. An exponential function of the form y = abt can be used, where y represents the cost of goods, t represents the year, and a and b are constants to be found.

Given that the goods cost $100 in 1967, our initial condition gives us a as $100. We then use the information from 1977 (t=10) to solve for b. Plugging in the values, we get $184.50 = 100*b10, which solves to b approximately equal to 1.0653. Therefore, the exponential function modeling the CPI data is y = 100(1.0653)t.

To estimate the cost of goods in 2005, we substitute t with 38 (2005 - 1967), resulting in an estimated cost of goods y ≈ 100(1.0653)³⁸ ≈ $1019.03. This estimation illustrates how the Consumer Price Index can indicate changes in purchasing power and the cost of living over time.

Answer:

57 pounds weight is 95 percent of the limit .

Step-by-step explanation:

Formula

[tex]Percentage = \frac{Part\ value\times 100}{Total\ value}[/tex]

As given

A rocking horse has a weight limit of 60 pounds .

Here

Percentage = 95%

Total value = 60 pounds

Put in the formula

[tex]Percentage = \frac{Part\ value\times 100}{Total\ value}[/tex]

[tex]95 = \frac{Part\ value\times 100}{60}[/tex]

[tex]Part value = \frac{95\times 60}{100}[/tex]

[tex]Part value = \frac{5700}{100}[/tex]

Part value = 57 pounds

Therefore 57 pounds weight is 95 percent of the limit .

Answer:

57 pounds is 95 percent of the limit.

Step-by-step explanation:

Given the statement: A rocking horse has a weight limit of 60 pounds.

⇒Weight limit of rocking horse  = 60 pounds.

To find what weight is 95 percent of the limit.

Let x be the weight.

then;

x = 95% of 60

[tex]x = \frac{95}{100} \times 60[/tex]

or

x = [tex]\frac{95 \times 60}{100} = \frac{5700}{100} = 57[/tex]

therefore, 57 pounds is 95 percent of the limit.

Answer:

The number of black ink pen are 15 pens.

Step-by-step explanation:

As given

Jared bought a package of pens containing 20 pens.

[tex]if\ \frac{3}{4}\ of\ the\ pens\ have\ black\ ink.[/tex]

Thus

[tex]Number\ of\ black\ ink\ pens = \frac{3}{4}\times Total\ number\ of\ pens[/tex]

Putting the value

[tex]Number\ of\ black\ ink\ pens = \frac{3}{4}\times 20[/tex]

Number of black ink pens = 3 × 5

                                          = 15 pens

Therefore the number of black ink pen are 15 pens.

Jared has 15 pens with black ink, which is calculated by multiplying 3/4 by the total number of pens he has (20 pens).

To determine the number of pens with black ink that Jared has, you need to multiply the total number of pens by the fraction representing the pens with black ink. Jared has a package containing 20 pens, and 3/4 of these have black ink. Here's how you calculate it:

Find the fraction of pens with black ink: 3/4 of the pens.

Multiply this fraction by the total number of pens: 3/4 × 20 pens.

Calculate the product to find the number of pens with black ink: 3/4 × 20 = 15 pens.

Therefore, Jared has 15 pens that contain black ink.
