Step-by-step explanation:
A toy glider plane is launched from a height of 50 feet above the ground. If the plane descends at a constant rate of 1.3 feet per second, then its height, in feet, after s seconds can be found using the equation h = 50-1.3s. Use the equation to find the height of the glider 9 seconds after it was launched.
Answer:
38.3 feet
Step-by-step explanation:
h=50-1.3(9)
h=50-11.7
h=38.3

Jada is planning a kayak trip. She finds an expression for the time, T(s), in hours it takes her to paddle 10 kilometers upstream in terms of s, the speed of the current in kilometers per hour. This is the graph Jada gets if she allows s to take on any value between 0 and 7.5. What would be a more appropriate domain for Jada to use instead?
Answer:
A more appropriate domain would be all real numbers except x = 5.5
Step-by-step explanation:
Given that the domain of a rational function consists of the set of real numbers but excluding those real numbers that results in a zero in the denominator
The given graph of the function has a vertical asymptote at s = 5.5 which indicates a value for which the function is not defined and at x = 5.5, and as such the value (5.5) of the asymptote is not a member of the function's domain
The values of the domain of a function consisting of a reciprocal must exclude does that result in a zero denominator.
The domain of the function that represents Jada's trip is the set of input value the function can take
The appropriate domain is: all real numbers except x = 5.5
From the graph, we can see that:
The x-value starts at negative infinity, and ends near 5.5The x-value then continues near 5.5, and ends at positive infinityThis means that the input of the graph cannot be 5.5
Hence, an appropriate domain would be: [tex]\mathbf{x \ne 5.5}[/tex]

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
Given;
Gianna walked 12 miles in 6 hours
6hours= 12 miles
1hour= 12/6miles
1hour= 2miles
Therefore, the rate of gianna by unitary will be 2mph

Hello!! I need help with square root please help me!!!
Ok so what you need to do is you need to get all the numbers and see which one is the right number so...
A. y = 11.2 that is wrong
B. y = 25 is wrong
C. y = 5 is right
D. y = 15 is wrong.
C is right because it would be 5 times 5 times 5. SO 5 times 5 is 25, and then u times it by 5 and you get 125!
C is correct
Hope this helps!!
Answer:
This is actually a cube root, since you need a cube root to cancel out the cube.
C, y = 5
Step-by-step explanation:
125 = 5 × 5 × 5 = 5^3
5 × 5 × 5 = 25 × 5 = 125.
Therefore the cube root of 125 = 5.
It REALLY helps when you break these into factors.
[tex] \sqrt[3]{125} = 5 , \: as \: {5}^{3} \: = 125 [/tex]
This is essentially asking what multiplied by itself three times is equal to 125.
Process of elimination can be used for any number cubed that is ≠ 125
i.e : 11.2^3 ≠ 125
11.2^3 = 11.2 × 11.2 × 11.2 = (11.2-1.2)(11.2+1.2)(11.2) = (11.2)((10)(12.4) + 1.2^2) = 124 + 1.44 = (125.44)(11.2) = 125.44(10+1+(2/10)) = 1254.4 + 125.44 + 25.088 = 1404.928 ≠ 125, y ≠ 11.2
I.e : 25^3 = 25 × 25 × 25 = 625 × 25 = (600+25)(25) = 625 + 6(25)(100) = 15000 + 625 = 15625 ≠ 125, y ≠ 25.
And i.e: 15^3 = 15 × 15 × 15 = 225 × 15 = (225)(10+5) = 225(10) + 225(10/2) = 2250 + 2250/2 = 2250 + 1125 = 3375 ≠ 125, y ≠ 15.

What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Point S is between points R and T on RT.
RS = 2x - 8
ST = 3x - 10
RT = 17
From the above information:
RT = RS + ST
17 = 2x - 8 + 3x - 10
17 = 5x - 18
35 = 5x
x = 35/5
x = 7
RS = 2x - 8 = 2(7) - 8 = 6 units
ST = 3x - 10 = 3(7) - 10 = 11 units
RT = 17 units
Thus, the value of x is 7 and the measure of the line segment RS is 6 units, ST = 11 units, and RT = 11 units.

Determine the intercepts of the line.
y= -3.6 +12
y-intercept:
X-intercept:
Need to know NOW
Answer:
y = 12
x = 10/3
Step-by-step explanation:
y = -3.6x + 12
From this equation, which is in slope intercept form (y = mx+b), we already know that b represents the y-intercept, so that means the y-intercept is 12.
To find the x-intercept, we need to make y equal 0 to find x. So:
0 = -3.6x + 12
-3.6x = -12
x = 3.33333 --> 3 1/3
x = 10/3

Jacinda made 16 baskets during the basketball game. Greta made 4 baskets. The number of baskets Jacinda made is how many times more than the number of baskets Greta made? Choose the answer that has the correct equation AND the correct solution to the equation.
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Jacinda = 16 baskets
Greta = 4 baskets
The number of baskets Jacinda made is how many times more than the number of baskets Greta made?
To obtain this :
Number of baskets Jacinda made / Number of baskets Greta made
If Jacinda's basket = J ; Greta's basket = G
J / G
16 / 4 = 4
Hence, Number of basket Jacinda made is 4 times more than that made by Greta

Using the approximation 3.14 for pi, what is the radius of a circle with circumference 69.1 m?
Answer:

Step-by-step explanation:
Circumfrence = 2 x pi x r.
making radius, r the subject of relation, you.get 11.003184713
Answer:
Hey!
Your answer is 11cm!
Step-by-step explanation:
So to get the radius from the Circumference we need both the Circumference and the value of pi...3.14
Radius = [tex]\frac{C}{2\pi }[/tex] ... (that's the formula)
WE SUBSTITUTE IN:
Radius = 69.1/2 x 3.14
69.1/6.28
This equals = 10.99760656765
