Answer:

h(t) = -0.25t + 6.25

Step-by-step explanation:

Given that :

Height of candle after burning for 1 hour = 6

Height of candle after burning for 3 hours = 5.5

The linear model to show the height ight of candle after burning for h hours :

The height change per hour of burn ; this is the slope ;

Change in height / Change in time ;

Time = 1 hour ; height = 6

Time = 3 hours ; height = 5.5

Slope = (5.5 - 6) / (3 - 1) = - 0.5 / 2 = - 0.25

This means candle height decreases ; - 0.25 ft per hour :

Based on the linear, slope, intercept equation ;

y = mx + c

Candle height, h

h(t) = mt + c

c = intercept, we can obtain this thus ;

Using the height at 1 hour and slope;

After an hour burn :

6 = - 0.25t + c

t = 1

6 = - 0.25(1) + c

6 = - 0.25+c

6+0.25 =, c

c = 6.25

Hence ; to calculate height, h after burn time &

h(t) = -0.25t + 6.25

Answer:

D

Step-by-step explanation:

9(3)^-4

3^2 × (3^-4)

in algebraic expression a^n × a^m = a^n+m

3^2+(-4)

3^-2

but 3^-2 = 1/3²

1/3²= 1/9

The option (4) is correct i.e., when [tex]x=-4[/tex] then

[tex]f(x) = 9(3)^x\\\\f(x)=\frac{1}{9}[/tex]

What is the equation?

The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

Here given equation is

[tex]f(x)=9(3)^x\\\\\\x=-4\\\\\\f(-4)=9(3)^{-4}\\\\f(-4)=\frac{9}{(3)^4}\\\\f(-4)=\frac{9}{81}\\\\f(-4)=\frac{1}{9}[/tex]

Hence, the option (4) is correct i.e., when [tex]x=-4[/tex] then

[tex]f(x) = 9(3)^x\\\\f(x)=\frac{1}{9}[/tex]

Answer:

[tex]{ \boxed{ \tt{4x + 4x \: → \: 8x}}} \\ \\ { \boxed{ \tt{3x + 5x + 8 \:→ \: 8x + 8 }}} \\ \\ { \boxed{ \tt{ - 7x + 4 + 3x \: → \: - 4x + 4}}} \\ \\ { \boxed{ \tt{4x + 4x + 4x + 4x \: → \: 16x}}}[/tex]

Answer:

4x + 4x → 8x

3x + 5x + 8 → 8x + 8

-7x + 4 + 3x → -4x + 4

4x + 4x + 4x + 4x → 16x

Step-by-step explanation:

The left side consists of a series of expressions and the right side is the list of choices to match to. This is simple math if you already know how to combine like terms. Combining like terms is combining numbers that represent the same value. Take a look at 4x + 4x for example, 4x and 4x are two numbers with the same value. Not that they both have the number 4, but that they have the same special variable. If there are two or more numbers with the same variable like x for example, combine the two, meaning you add the numbers. Just don't add the variables because clearly, the variable is an unknown number so you can't add variables. Instead, you can apply the same variable to the sum of two or more numbers. So 4x + 4x equals 8x. Do the same process again to the other 3 expressions. Also, you can't add a number with a variable to a number alone. They don't represent the same value.

3x and 5x are the same value so combine them. Now you only have 8x + 8 left as the simplified version of the expression.

-7x and 3x are the same value so combine them. Don't forget that the 7 is negative. Use a calculator if needed. Now you only have -4x + 4 as the simplified version of the expression.

Similar to 4x + 4x in the first expression, just add all of the numbers up. There isn't a number alone in this expression. 16x should be your final answer.

Step-by-step explanation:

The type of Polygon shown as given in the question with its' shape is called; Convex Hexagon

We are told that the polygon has 6 sides and that no angle goes inside the shape.

Now, a polygon with 6 sides is called a hexagon. However, in this case the name will be a convex hexagon because it will have a hexagonal shape with no interior angle greater than 180°.

Despite that said, regular hexagons will always be called convex hexagon while Irregular hexagons can also be called convex hexagons.

Answer:

24 sq. m

Step-by-step explanation:

Area of the grass part = area of the park - area of sand area

Park:

l = 6 m  ; w = 5 m

Area of park = l * w = 6*5 = 30 sq.m

Sand :

l = 3 m ; w = 2 m

Area of sand part = 3*2 = 6 sq.m

Area of grass part = 30 - 6 = 24 sq.m

Answer:

24 square meters is the area of the grass part.

Step-by-step explanation:

Multiply both sides of the "sand" section, which are 2 and 3. You get 6.

Now multiply two numbers, 5 and 6, to find the square meters of the whole area, including grass and sand, you get 30.

Now since you only need the area of the grass area, you subtract the area of the sand area, which is 6 sq meters, from the whole area, 30 sq meters, leaving you with 24 square meters as the answer.

2x+3y=1

The difference between this two equations is x+y so:

x+y

=1-(-4)

=1+4

=5

I'm not sure what the question is asking to find, but I have already helped you find the value of x+y, good luck with the rest I guess :))
