What is 14/18 as decimal

Answer:

(i)23.77kg

(ii)(ii) the inequality 20≤t≤48 means the weight of the dogs determined is for dogs that have the age of 20 weeks or less to the age of 48 weeks not more.

(iii)44 weeks

(iv)0.92

(v)Attached

(vi)The value of weight will be negative,which is unrealistic.

Step-by-step explanation:

(i)Given that the weight is modeled by the equation;

w = 0.92t−0.15 (20 ≤ t ≤ 48)

then substitute the value of t in the equation given that t=26 weeks

w=0.92*26-0.15=23.77kg

(ii) the inequality 20≤t≤48 means the weight of the dogs determined is for dogs that have the age of 20 weeks or less to the age of 48 weeks not more.

(iii)Apply the equation for weight

w=0.92t-0.15

40=0.92t-0.15

40+0.15=0.92t

40.15=0.92t

40.15/0.92=t

43.6⇒⇒44 weeks

(iv) Here , write the equation in slope intercept form of y=mx+c where m is the slope and c is the y-intercept

w=0.92t-0.15

y=mx+c

m=0.92

(v)sketch attached

(vi)

At birth, t=0 hence to find weight

w=0.92t-0.15

w=0.92*0-0.15

w=0-0.15

w=-0.15

The model cannot be extended to model accurately the dog's weight at birth because you will get a negative value for weight which is not realistic.

A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 401 is about 20.025. Thus, the square root of 401 is not an integer, and therefore 401 is not a square number.

Answer:

apparently In what I believe, 401 is not a perfect square mate!

Step-by-step explanation:

401 is an odd number, because it is not evenly divisible by 2.

What is a number system?

A number system is described as a technique of composing to represent digits. It is the mathematical inscription for describing the numbers of a given set by using numbers or other characters in a uniform method. It delivers a special presentation of every digit and describes the arithmetic structure.

Fraction is defined as the number of compositions that constitutes the Whole.

Here,
Given number = 0.888
Fraction = 0.888 = 888 / 1000
Faction = 111 / 125

(h, k) - center

r - radius

We have:

[tex](x-5)^2+(y+6)^2=42\\\\(x-5)^2+(y-(-6))^2=42[/tex]

Answer:

Using the graph as your guide, complete the following statement.

The discriminant of the function is

Step-by-step explanation: Remember a parable of the form f(x) = a[tex]a x^{2} + bx + c[/tex], satisfy:

(1) has only one root if and only if [tex] b^2 - 4ac = 0[\tex]

(2) has two real roots if and only if  [tex] b^2 - 4ac > 0[\tex]

(3) has two complex roots if and only if  [tex] b^2 - 4ac < 0[\tex].

The number b^2 - 4ac is called the discriminant of the parable f(x).

From the graph we can see that the parable has only one root approx in x =1. Thus from point (1) we can conclude that the discriminant should be zero.

PD: a root of a polynomial f(x) is a number a such thast f(a) =0.

Area of the walkway = 8x + 24

Step-by-step explanation:

Area of the total backyard = [tex]l\times b[/tex]

Area of total backyard = [tex](x+6)\times (x+4) = x^{2} +10x + 24[/tex]

Now, Area of the rectangular garden = [tex]l\times b[/tex]

Area of the rectangular garden = [tex]x (x+2) = x^{2} + 2x[/tex]

Now area of the walkway poured with concrete = Area of the backyard - Area of the rectangular garden

= [tex](x^{2} +10x +24) - (x^{2} +2x)[/tex]

= [tex]x^{2} + 10x +24 - x^{2} -2x[/tex]

Answer:

Considering is a compunded increase rate of the yearly car insurance fee and x is the initial value of the insurance fee then

x×(1.05)^12=$86.82

×=$86.82/(1.05)^12

The cost of his insurance before it increased is $82.48.

Here,

The cost of Mr. Patten’s car insurance increased by 5% to $86.82 per month.

We have to find the cost of his insurance before it increased.

What is Percentage?

A percentage (from Latin per centum "by a hundred") is a number or ratio expressed as a fraction of 100.

Now,

The cost of Mr. Patten’s car insurance increased by 5% to $86.82 per month.

Increased cost = [tex]\frac{5}{100} * 86.82 = 4.34[/tex]

Hence, The cost of his insurance before it increased = $86.82 - $4.34

                                                                                 = $82.48

So, The cost of his insurance before it increased is $82.48.

Step-by-step explanation:

If these 3 points are collinear, then we can find the slope of the linear function using any 2 of those points.  Suppose we use (-4, 3) and (0, 1):  

As we move from (-4, 3) to (0, 1), x increases by 4 and y decreases by 2.  Hence, the slope of this lilne is m  = rise/run = -2/4, or m = -1/2.

Using the slope-intercept formula y = mx + b and replacing y with 1, x with 0 and m with -1/2, we get:

1 = (-1/2)(0) + b, or b = 1.  Then the desired equation is y = f(x) = (-1/2)x + 1

Answer:

Step-by-step explanation:

Two lines are perpendicular if the first line has a slope of [tex]m[/tex] and the second line has a slope of [tex]\frac{1}{-m}[/tex].

With this information, we first need to figure out what the slope of the line is that we're given, and then we can determine what the slope of the line we're trying to find is:

[tex]5x - 2y = -6[/tex]

[tex]-2y = -5x - 6[/tex]

[tex]y = \frac{5}{2}x + 3[/tex]

We now know that [tex]m = \frac{5}{2}[/tex] for the first line, which means that the slope of the second line is [tex]m = \frac{-2}{5}[/tex]. With this, we have the following equation for our new line:

[tex]y = \frac{-2}{5}x + C[/tex]

where [tex]C[/tex] is the Y-intercept that we now need to determine with the coordinates given in the problem statement, [tex](5, -4)[/tex]:

[tex]y = \frac{-2}{5}x + C[/tex]

[tex](-4) = \frac{-2}{5}(5) + C[/tex]

[tex]-4 = -2 + C[/tex]

[tex]C = -2[/tex]

Finally, we can create our line:

[tex]y = \frac{-2}{5}x - 2[/tex]

[tex]5y = -2x - 10[/tex]

[tex]2x + 5y = -10[/tex]
