Answer:
x = 11.2
Step-by-step explanation:
hypotenuse = 8.4 (radius) + 5.6 = 14
using the Pythagorean theorem:
x² = 14² - 8.4² = 196 - 70.56 =125.44
x = √125.44 = 11.2

Step-by-step explanation:
Si a la mitad de un número le restas su tercera parte, y, a este resultado, le sumas 85/2,
obtienes el triple del número inicial. ¿De qué número se trata?
Answer:
x = 15
Step-by-step explanation:
Llamaremos x al número que buscamos, entonces:
la mitad de x es x/2, la tercera parte es x/3, y el triple del número es 3*x
De acuerdo al problema :
(x/2 - x/3 ) + 85/2 = 3*x
Esta es una ecuación de primer grado pasamos a resolverla.
( 3*x - 2*x ) /6 + 85/2 = 3*x
x/6 + 85/2 = 3*x
( x + 255)/6 = 3*x
x + 255 = 18*x
17*x = 255
x = 255/17
x = 15

Function is represented by the equation y=3x-2. and tunction Fis shown on the graph below. Which statement about both functions is true?
HURRY PLEASE
Answer:
I believe it would be both functions have a y-intercept of -2.
Step-by-step explanation:
Hope this answer is correct and helps you. :)
The true statement about the function is that both functions have a y-intercept of -2.
How to explain the functionIf both functions have a y-intercept of -2, it means that they pass through the point (0, -2). The y-intercept is the value of y when x is equal to 0.
Here are many functions that have a y-intercept of -2. Here are a few examples:
Linear function: y = 2x - 2
Quadratic function: y = x² - 2
Logarithmic function: y = log(x) - 2
In general, any function of the form y = mx + b, where m and b are constants, will have a y-intercept of b. So, as long as b = -2, the function will have a y-intercept of -2.

3. A soccer player heads a ball from a height of 6 feet with an initial vertical velocity of 20 feet per second. The height h in feet of the ball is given by h= –16t + 20t +6,
where t is the time elapsed in seconds. How long will it take the ball to hit the
ground if no other players touch it? State the method you used to solve this
quadratic equation and why you chose that method.
Answer:
Part A
1.5 seconds
Part B
By substitution and factorization because h = 0 at ground level
Step-by-step explanation:
Part A
The height from which the soccer player heads the ball, h = 6 feet
The initial velocity of the ball, v = 20 ft./s
The height of the ball in feet, h = -16·t² + 20·t + 6
From the given equation of the ball, we have;
At the initial height, t = 0, from the given equation, h = 6
At the ground level, the height, h = 0, therefore, we get;
0 = -16·t² + 20·t + 6
Factorizing using a graphing calculator gives;
0 = 2 × (-8·t² + 10·t + 3) = -2 × (8·t² - 10·t - 3) = -2 × (2·t -3)·(4·t + 1)
∴ (2·t -3)·(4·t + 1) = 0
t = 1.5 or t = -1/4 = -0.25
Therefore;
The time it takes the ball to hit the ground, t = 1.5 seconds.
Part B
The method used in solving the given quadratic equation is by plugging in the value of 'h' as h = 0 in the given equation and factorizing the result because at ground level, the height, h = 0.
What is the value of x in the equation 2x + 3y = 36, when y = 6? A. 8 B. 9 C. 27 D. 36
Answer:
x = 9
Step-by-step explanation:
When y = 6 :
2x + 3y = 36
2x + 3(6) = 36
2x + 18 = 36
2x = 36 - 18
2x = 18
x = 9

Jordan has saved $15. He doubles the amount he saves each week. Does this represent an exponential function? Why?
Answer:
it does not
this is because his income increases at a constant rate. At any given week, his income increases by double
Step-by-step explanation:
An exponential function is usually in the form : [tex]a^{x}[/tex]
where a = positive constant other than 1
x = variable component
for example ,
Assume that Jordan saves $15. he increases this amount by 10% weekly. this statement represents an exponential function.
The amount he would have in 7 weeks = 15 x (1.1)^7 = 29.23
Answer:No, this does not represent an exponential function because his savings does not increase by a constant ratio.

Answer:
d) [tex]\frac{9\pi }{4}[/tex]
Step-by-step explanation:
[tex]\frac{9\pi }{4} = 2\pi + \frac{\pi }{4}[/tex]
The correct options are a and d because -7pi/4 and 9pi/4 are the required angles.
Important infromation:
The given angle is [tex]\dfrac{\pi}{4}[/tex].Angles:The angles [tex]\theta\pm 2n\pi [/tex] represent the same point on the unit circle as [tex]\theta[/tex].

Estimate 12.32+7.636 by first rounding each number to the nearest tenth.
pls help need the right answer thank u
===========================================================
Explanation:
12.32 rounds to 12.3 when rounding to the nearest tenth (aka one decimal place). The digit in the tenths place stays the same because the next digit over is not 5 or larger.
7.636 rounds to 7.6 when following the same rule

(a) Contrast the shapes of the data sets displayed in the box-and-whisker plots in Question 1. Explain
what the difference in the shapes means in context of the situation.
(b) Compare the spread of the data sets. Discuss both the overall spread and the spread within the
boxes.
(c) Use an appropriate measure of central tendency to compare the center of the data sets. Explain what
the difference in those measures means in context of the situation.
Answer:
Kindly check explanation
Step-by-step explanation:
A.)
Differentiating based on the shape of the box and whisker plot.
The first plot, named shrella depicts a skewed distribution, (negative skew) highlighted by the long whisker (tail) to the left with the median also shifting towatds to the right of the box away from the box center. This could mean that the time difference between the coins aren't even and older coins seem to exhibit a larger time gap than newer coins.
The second plot however. VENITA, depicts a distribution which could be described as normal, as the whiskers are aodt of equal length and the median centered in the middle of the box. This could mean that Venita's coins are evenly spread out based time.
B.)
As for the overall spread, Shrella's plot covers a wider range, hence (larger spread) than Venita's plot. Thanks to the long whiskers in Shrella's plot.
For the spread within the boxes, Venita's plot has a larger within box spread than Shrella. With Venita's plot has a wider box tham Shrella's box plot.
C)
The appropriate measure of centre to be used is the median which is denoted by the vertical line in between the box. Shrella's plot has a median value of about 68 while Venita's has a median value of 60. The median value are still s bit close or similar.
