The height of the missile above the ground is 72 meters at 0.8 sec and 2 sec.
What is an equation?An equation is an expression that is used to show the relationship between two or more numbers and variables.
Let h(t) represent the height of the missile above the ground at time t. Given that:
h(t) = -16t³ + 100t
When the height is 72 m:
72 = -16t³ + 100t
16t³ - 100t + 72 = 0
t = 2 seconds and t = 0.8 seconds
The height of the missile above the ground is 72 meters at 0.8 sec and 2 sec.

A wire is bent to form a square of side 22 cm. If the wire is re bent to form a circle, its radius is with steps
Step-by-step explanation:
the circumference of a circle is
C = 2×pi×r
with r being the radius.
the square side length is 22 cm. so, the circumference or perimeter of the square (and therefore the length of the wire) is
4×22 = 88 cm.
now, it is the same wire of the same length that is now forming a circle.
so, the circumference of the square is also the circumference of the circle.
therefore,
88 = 2×pi×r
44 = pi×r
r = 44/pi = 14.00563499... cm
so, rounded, radius = 14 cm.
Answer:
The other answer is correct
Step-by-step explanation:
The circumference of the circle and the square will be the same so you solve the equation
4*22 = 2 pi r where r is the radius.

Which of the triangles in the two figures above is a right triangle? Explain your choice using
the Pythagorean Theorem to prove it. Note: the figures are not drawn to seale.
Figure B
Step-by-step explanation:The Pythagorean Theorem is [tex]a^2 + b^2 = c^2[/tex], where c is the longest side of the triangle (the hypotenuse).
To find the side length of each square, you have to square root the area of each square. This means that Figure A has side lengths of 3, 6 and 8 units. Figure B has side lengths of 5, 12 and 13 units.
In Figure A, if the triangle is right-angled, the equation [tex]3^2 + 6^2 = 8^2[/tex] must be correct. 9 + 36 = 45. 45 is not equal to 64, so the triangle is not right-angled.
In Figure B, if the triangle is right-angled, the equation [tex]5^2 + 12 ^2 = 13^2[/tex] must be correct. 25 + 144 = 169. 169 is 13 squared, so the triangle is right-angled.
Alternatively, as you are already given the square values for each side length, there is no need to square root and square again. You can just test if the two smaller areas equal the larger area, but the explanation above uses a more detailed example of the Pythagorean Theorem.

Answer:
y = –(1/2)x + 7
Step-by-step explanation:
Slope intercept form is y = mx + b
m is the slope
When the slope is the same the lines are parallel
here the slope is –1/2
therefor
y = –(1/2)x + 7 is parallel

find the value of x that makes this true. M<2= -9 + 7x
See picture for full problem. Please and thank you!
Step-by-step explanation:
the triangle is an Isosceles triangle
let the another two angles be 2x
and apply angle sum property of triangle here
2x + 72° = 180
2x = 180 - 72
2x = 108
x = 108/2 = 54
therefore,
angle 2 = 54°
a/q
angle 2 = -9 + 7x
now,
54° = -9 + 7x
or
-9 + 7x = 54°
7x = 54 + 9 = 63°
x = 63/7 = 9
x = 9
therefore, value of x is 9.

What is the equation of this line in slope-intercept form?
A: y = 4x + 1
B: y=−4x+1
C: y=4x−1
D: y=−14x+1
Answer: B
Step-by-step explanation:
The slope-intercept is usually written as y = mx + b form, where m is the slope, and b is the y-intercept. The y-intercept is the y value when x is equal to 0.
We can first eliminate C, because the y-intercept of the graph is 1.
To solve for slope, which is the m, choose two points, (-1, 5) and (1, -3).
Slope = (y2 - y1) / (x2 - x1)
= (-3 - 5) / (1 - (-1))
= (-3 - 5) / (1 + 1)
= -8/2
= -4
Plug in the slope and y-intercept, we get y = -4x + 1

The rational numbers between -3 and -2 are;
-5/2, -9/4 and -11/4
Rational NumbersRational numbers are numbers that can be represented as the quotient of two integers but not equal to zero.
Now, to find the rational number between -3 and -2, we will use the formula;
x = ½(a + c)
x = ½(-3 + (-2))
x = -5/2
Another rational number is;
x = ½(-(5/2) + (-2))
x = ½(-9/2)
x = -9/4
Using the same pattern, we can still get another one as -11/4
In conclusion, the three rational numbers will be -5/2, -9/4 and -11/4

Answer:
0.9 + n = 5.2
Step-by-step explanation:
Think about it, 0.9 increased by a number is 5.2
In other words, increasing 0.9 by a number will equal 5.2
So, increasing = adding, right?
Adding 0.9 to a number will equal 5.2
0.9 + n (a number) = 5.2
h(x)=2x+5 for h(x+3)
solve for h(x+3)
pls help aaaaaaaaaaaa i
Answer:
According to transitive Property of equality : If a =b and b = c then a = c
In this problem you are given with 2 equations:
h(x) = - 2x + 5 ---- 1
h(x) = 3 ------ 2
Apply transitive Property of equality to equation 1 and 2
- 2x + 5 = 3 Now solve for x.
-2x + 5 - 5 = 3 – 5 subtract 5 on both sides.
-2x = -2
(-2x)/(-2) = (-2) / (-2) Divide with -2 on both sides.
X = 1

Finite geometric series:
Hi, I want to ask a question, is about... for example, take the sequence 1,2,4,8,... Notice that each number is twice the value of the previous number. So, a number in the sequence can be represented by the function f(n) = 2^n-1. One way to write the sum of the sequence through the 5th number in the sequence is E^5 n-1^2n-1. This equation can also be written as S5 = 2^0 + 2^1+2^2+2^3+2^4. If we multiply this equation by 2, the equation becomes 2(S5) = 2^1+2^2+2^3+2^4+2^5.
What happens if I subtract the two equations and solve for S5? Can I use this information to come up with a way to find any geometric series Sn in the form E^a n-1^bn-1?

Which of the following lines has a negative slope?
Is it Red
Is it Black
Is it Blue
Answer:
black line <3
Step-by-step explanation:
the slope is -2 :)
A negative slop occurs when the rate of change is negative. Looking at the options we have, we can pick a point from each line. The Red line will display a positive slop, the Blue line will display a positive slope, but the Black line will display a negative slope. Therefore, the Black like has a negative slope.

Which product is greater than 63?
7/8 x63
3/2 x 63
4/5 x 63
2/3 x 63
Answer:
The answer is 3/2 x 63
Step-by-step explanation:
3/2*63 = 189 / 2 = 94.5
7/8*63 = 441 / 8 = 55.125
2/3*63 = 126 / 3 = 42
4/5*63 = 252 / 5 = 50.4
Therefore the answer is 3/2 x 63 because it’s product is greater than 63.
