Question 4
In order to ensure that the roof consists of right angles, an architect measures the diagonal to create a triangle. If the dimensions of the
triangle are 9.5 feet, 16 feet, and 18.5 feet, is the triangle a right triangle?
Answer:I have a question
Step-by-step explanation:
About that question is it a right triangle or no
The triangles with side lengths 9.5 feet , 16 feet and 18.5 feet is an acute triangle
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the height of the triangle is AB = 16 feet
The base of the triangle is BC = 9.5 feet
The hypotenuse of the triangle is AC = 18.5 feet
And , for a triangle , if a² + b² > c² , it is an acute triangle
Substituting the values in the equation , we get
( 9.5 )² + ( 16 )² > ( 18.5 )²
90.25 + 256 > 342.25
346.25 > 342.25
Hence , the triangle is an acute triangle

Answer:
C.) 8.68686 × [tex]10^{7}[/tex]
D.) 4.1688 × [tex]10^{2}[/tex]
Step-by-step explanation:
For C.) you take 8.69 and multiply that by [tex]10^{7}[/tex] and you'll get 86900000
Then you take 3.14 and multiply that by [tex]10^{4}[/tex] and you'll get 31400
So then you take 86900000 and 31400 and subtract it...
86900000 - 31400 = 86868600 and you convert 86868600 to scientific Notation.
Which would equal **** 8.68686 × [tex]10^{7}[/tex] *****
For D.) you take 4.32 and multiply that by [tex]10^{3}[/tex] and You'll get 4320
then you take 9.65 and multiply that by [tex]10^{-2}[/tex] and you'll get 0.0965
So then you take 4320 and 0.0965 and subtract it...
4320 - 0.0965 = 4319.9035 and you convert 4319.9035 to Scientific Notation.
Which would equal **** 4.1688 × [tex]10^{2}[/tex] ****
What is the recursive rule for the sequence? -1,-0.5,0,0.5,1,...
9514 1404 393
Answer:
C
Step-by-step explanation:
The subscript (n-1) is used to indicate the term previous to term (n). In this sequence, each term is 0.5 more than the previous term, so the recursive relation ...
[tex]a_n=a_{n-1}+0.5[/tex]
is the appropriate one. This matches choice C.
__
Additional comment
Of course, if the next term is 0.5 more than the last, then the previous term is 0.5 less than the present one. The sequence can be described in this "backward" fashion by the recursive relation of choice A. While that does work to describe the sequence, it is usually not the form we desire for a recursive relation.

I'm getting confused is it possible for some help??
Answer:
11i= √-1
Step-by-step explanation:
So first take 1 to the other side so we can leave the numbers with I on one section. So when we take 1 to the other side it becomes negative so 0-1 = -1. Since the 8 is squared to get rid of it were going to put a square root on the whole equation. √8i² + 9i = √-1 and we have to put the square root on the other side of the equation to make it equal. So on the other side we now have 8i + 3i *because the square root of 9 is 3* and then the -1 stays like that so its 11i= √-1 because we combine the 8i and 3i. Happy I could help!!!
The function h(t)=−16t(t−7) models the height of an object at any time t after it is launched, where t is measured in seconds. After how many seconds will the object hit the ground?
Answer:
2.65secs
Step-by-step explanation:
Give:
The function h(t)=−16t(t−7) models
the object will hit the ground at h= 0
h(t)=−16t(t−7)
0= -16t(t−7)
0= -16t^2 + 112
16t^2 = 112
t^2 = 7
t= √7
t=2.65secs
Hence, the object object hit the ground at 2.65secs

Graph the line with the equation y=-2/5x+1
Answer:
Step-by-step explanation:
slope = -2/5
y intercept = (0,1)
The graph of the line y=-2/5x+1 is given below.
To graph the line with the equation y = -2/5x + 1, we can use the slope-intercept form of a linear equation, y = mx + b, where m is the slope and b is the y-intercept.
In this case, the slope is -2/5, which means that for every increase of 1 unit in the x-coordinate, the y-coordinate decreases by 2/5 units. The negative sign indicates that the line slopes downward from left to right.
The y-intercept is 1, which is the point where the line crosses the y-axis.
To plot the line, start by marking the y-intercept at (0, 1) on the coordinate plane. From there, use the slope to find additional points. For example, if you move 5 units to the right (because the denominator of the slope is 5) from the y-intercept, the y-coordinate will decrease by 2 units, giving you the point (5, -1).

which statements are true about the graph of function f?
f(x)= log x
Answer:
I believe the correct answer here is C!
Step-by-step explanation:
The option (A) is correct.
What is graphs of logarithmic function?"The logarithmic function y = log b x is the inverse function of the exponential function y = b x. We can now proceed to graphing logarithmic functions by looking at the relationship between exponential and logarithmic functions".
For the given situation,
[tex]f(x)=logx[/tex]
Plot the graph of [tex]f(x)=logx[/tex] .
From the graph shown below, the region of the graph lies in the domain of { x|0 < x < ∞ } and approaches as 0 as x decreases.
Hence we can conclude that the option (A) is correct.
