Answer:

y + 3 = -y + 9

-y         -y

3 = -2y + 9

+2y  +2y

2y + 3 = 9

     -3     -3

2y = 6

y = 3

Answer:

the answer is function 1 has the larger max. at (4,1)

Step-by-step explanation:

draw function 2 : the vertex  is (1,-2)

the vertex of function 1 is (4,1)

The function 1 has a greater maximum value than function 2, and the ordered pair is (1,4).

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

Linear function is a function whose graph is a straight line

We are given that;

f(x) = -x2 + 2x - 3

Now,

To find the maximum value of a function, we can use the vertex form of a quadratic equation, which is y=a(x−h)2+k

, where (h,k) is the vertex of the parabola. The maximum value of the function is the y-coordinate of the vertex.

For function 1, we can rewrite it as [tex]$$f(x) = -(x-1)^2 + 4$$[/tex]

by completing the square. This means that the vertex of function 1 is (1,4) and the maximum value is 4.

For function 2, we can rewrite it as

[tex]$$f(x) = -\frac{1}{4}(x+2)^2 - 2$$[/tex]

by completing the square. This means that the vertex of function 2 is (−2,−2) and the maximum value is -2.

Therefore, by the given function answer will be (1,4).

Answer:

s = [tex]\frac{3}{10}[/tex] m

Step-by-step explanation:

Given s varies directly with m then the equation relating them is

s = km ← k is the constant of variation

To find k use the condition s = 9 when m = 30 , thus

9 = 30k ( divide both sides by 30 )

k = [tex]\frac{9}{30}[/tex] = [tex]\frac{3}{10}[/tex]

s = [tex]\frac{3}{10}[/tex] m ← equation of variation

Answer:

[tex]L(t) = 1,100*(1+0.87)^{\frac{t}{2.4}}[/tex]

Step-by-step explanation:

The locust population grows according to an exponential model with the following general formula:

[tex]L(t) = L_0*(1+r)^{\frac{t}{T}}[/tex]

Where 'L0' is the initial locust population, 'r' is the increase rate after 'T' days, and 't' is the time passed, in days.

Applying the given data, the function that models the locust population t days since the first day of spring is:

[tex]L(t) = 1,100*(1+0.87)^{\frac{t}{2.4}}[/tex]

Answer:

Step-by-step explanation:

First find total the weight of all red footed macaws whic is 525(2)=1050

and then the blue and gold macaws 800(3)= 2400

So add them both together yu get 3450grams or 3.45kg

So it is closer to 3kg because the total weight is under 3.5kg so that means you round down to 3kg. If it was 3.5kg you would round up to 4kg but their combined weight is not more than 3.45kg

Answer:

4(3x+2)

Step-by-step explanation:

Just factor the expression.

An equivalent expression is,  4 (3x + 2)

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ 12x + 8

Now, We can find an equivalent expression as;

⇒ 12x + 8

⇒ 4 × 3x + 4 × 2

⇒ 4 (3x + 2)

Thus, An equivalent expression is,

⇒ 4 (3x + 2)

Answer:

Step-by-step explanation:

Answer:

a = (d-c)/b

Step-by-step explanation:

ab + c = d

ab = d -c

a = (d-c)/b

Answer: a = d - c/b

Explanation: To get a by itself, we first subtract c from both sides.

So we have ab = d - c.

Now divide both sides by b to get a = d - c/b.

Hey!!

Given,

Length(l)=8m

Breadth(b)=5m

Volume of a cuboid(V)=200 m^3

Height(h)=?

Now,

Volume of a cuboid=l*b*h

or,200=8*5*h

or,200=40h

or,h=200/40

h=5 meter

The height is 5 meter.

Hope it helps

Good luck on your assignment

Answer:

[tex]height = 5m[/tex]

Step-by-step explanation:

[tex]volume = l \times b \times h \\ 200 = 8 \times 5 \times h \\ 200 = 40h \\ \frac{200}{40} = \frac{40h}{40} \\ h = 5m[/tex]
