\Step-by-step explanation:
The value of a collectible toy is increasing exponentially. The two points on the graph
show the toy's initial value and its value 3 weeks afterward.
The question is incomplete. Here is the complete question.
Part A
The value of a collectible toy is increasing exponentially. The two points on the graph show the toy's initial value and its value 3 weeks afterward.
Express the toy's value t, in dollars, as a function of time w in weeks after purchase.
Part B
Write an expression to represent the toy's value 10 days after purchase
Answer and Step-by-step explanation: An exponential function is of the form: [tex]y=ab^{x}[/tex]
Part A
Translating to the question, the toy's value as a function of time is
[tex]t=ab^{w}[/tex]
To determine constants a and b, we use points given by graph.
First, (0,5) to find a:
[tex]5=a.b^{0}[/tex]
a = 5
Now, (3,10) to determine b:
[tex]10=5b^{3}[/tex]
[tex]b=\sqrt[3]{2}[/tex]
b = 1.26
The toy's value as a function of time in weeks is [tex]t=5.(1.26)^{w}[/tex]
Part B
Since, the function is in weeks:
1 week = 7 days
w weeks = 10 days
[tex]w = \frac{10}{7}[/tex]
Replacing w:
[tex]t=5.(1.26)^{w}[/tex]
[tex]t=5.(1.26)^{10/7}[/tex]
Expression that represents toy's value after 10 days is [tex]t=5.(1.26)^{10/7}[/tex].

Answer:
9(19)+13z=17
171+13z=17
13z=171-17
Z=154/13 is the answer
Step-by-step explanation:
Pls mark me in brain list
Answer:
z = -154/13
Step-by-step explanation:
1.) Add the numbers
9(2+17)+13=17
9(19) = 13z = 17
2.) Multiply the numbers
9 x 19 + 13z = 17
171 + 13z = 17
3.) Rearrange terms
171 + 13z = 17
13z + 171 = 17
4.) Subtract 171 from both sides of the equation
13z + 171 = 17
13z + 171 - 171 = 17 - 171
5.) Simplify
Subtract the numbersSubtract the numbers13z = -154

Angle X and Angle Y are supplementary angles. Angle x is sixteen degrees more than three times the size of Angle Y. What are the measures of Angle X and Angle Y?
Answer:
Step-by-step explanation:
If angles X and Y are supplementary
X+Y=90
x=16+3y
16+3y+y=90
4y=90-16
4y=74
y=74/4=18.50
x=90-18.50=71.50
Answer:
The measures of the angles are x=139° and y=41°
Step-by-step explanation:
Supplementary Angles
Supplementary angles add up to 180°. If x and y are two supplementary angles, then:
x + y = 180 [1]
Since angle x is 16 degrees more than 3 times the size of angle y:
x = 3y + 16 [2]
Substituting [2] into [1]:
3y + 16 + y = 180
Simplifying:
4y = 180 - 16 = 164
Dividing by 4:
y = 164/4 = 41
Substituting in [2]:
x = 3*41 + 16 = 139
The measures of the angles are x=139° and y=41°
P=a+b+c;P=36,a=9,b=10

Shring's dining room table is round and has a radius of 4.5 feet. What is the tabletop's are ?
Answer:
Step-by-step explanation:
Radius 4.5 feet what’s is the tabletop area
The area of the table top is 63.62 square feet.
What is area in geometry?
'In geometry, the area can be defined as the space occupied by a flat shape or the surface of an object.'
According to the given problem,
Radius of the table = 4.5 feet
Since, the table is round,
Area of a circle = [tex]\pi r^{2}[/tex]
= π × 4.5 × 4.5
= 63.617
Hence, we can conclude, the area of the table-top is 63.62 square feet.

6. The longest side of a 30° -60° - 90° triangle measures 8. What is the length of the
longer leg?
In an isosceles triangle the base angles are both 32 degrees, find the vertex
Answer:
116 deg
Step-by-step explanation:
note that an isoceles triangle always have 2 base angles that are equal.
Here we are already given one base angle of 32 deg. It follows that the other base angle must also be 32 deg.
We now have 2 angles of a triangle and we need to find the remaining one. Also recall that all 3 internal angles of a triangle sum to 180 deg. if we let the missing angle be x, then:
base angle + base angle + vertex angle = 180°
or,
32° + 32° + x° = 180°
64° + x = 180 deg
x = 180 - 64
x = 116 deg

Given a right triangle, find the length of the missing leg given the hypotenuse is 13 cm and the other leg is 5 cm. (Round to two decimal places.)
The length of the missing leg given the hypotenuse is 13 cm and the other leg is 5 cm would be 12 cm.
What is the Pythagoras theorem?The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.
a² + b² = c² (Pythagoras theorem)
where, c is the hypotenuse (longest length) of a triangle.
And a and b are the two other side of the triangle excluding the longest one.
Let x be the length of the missing leg of the given right triangle.
x² + 5² = 13²
x² = 13² - 5²
x² = 169 - 25
x² = 144
x = √144
x = 12
Hence, the length of the missing leg given the hypotenuse is 13 cm and the other leg is 5 cm would be 12 cm.

An orchard has 8 times many apple trees as pear trees. There are 981 trees in all. How many more apple trees than pear trees does have it?
Answer:
there are 763 more apple trees than pear trees
Step-by-step explanation:
so, first we write the words into equations.
8P = A because there are 8x apples per x pear, so to make it equal we must multiply pears by 8. P+A = 981. replacing "A" in the second equation with "8P" to get P+8P=981=9P divide both sides by 9 to get 109 pear trees. knowing this we can get 981-109=A=872 apple trees. the problem asks for A-P which we can replace the numbers to get (872)-(109)=763 more trees
There are 763 more Apple trees than Pear trees.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
let the number of pear trees be x.
An orchard has 8 times many apple trees as pear trees.
So, Apple trees = 8x
Now, total trees = 981
x+ 8x= 981
9x= 981
x= 981/9
x = 109
and, Apple trees = 8 (108)= 872.
So, there are 763 more Apple trees than Pear trees.
