An astronaut drops a rock off the edge of a cliff on the moon. The distance d(t), in meters, the rock travels after t seconds can modeled by the function d(t)= .5x^2. What is the average speed, in meters per second, of the rock between 5 and 10 seconds after it was dropped
Answer:
The average speed is 7.5 [tex]\frac{ m}{ s}[/tex]
Step-by-step explanation:
Speed is a physical quantity that expresses the relationship between the space traveled by an object and the time used for it.
Then, the average speed relates the change in position to the time taken to effect that change:
[tex]speed=\frac{change in position}{change in time}[/tex]
The change in position is the difference between the final position and the initial position, while the change in time is the difference between the final and initial time.
In this case, the starting and ending positions are calculated by replacing the times in the function of the distance d (t):
d(5)= 0.5*5²= 12.5 m
d(10)= 0.5*10²= 50 m
So:
change in position= final position - initial position= 50 m - 12.5 m= 37.5 mchange in time= 10 s - 5 s= 5 sReplacing in the definition of speed:
[tex]speed=\frac{37.5 m}{5 s}[/tex]
and solving you get:
speed= 7.5 [tex]\frac{ m}{ s}[/tex]
The average speed is 7.5 [tex]\frac{ m}{ s}[/tex]

Write the equation of the line, in point-slope form. Identify (x1, y1) as the point (-2, 2). Use the box provided to submit all of your calculations and final answers.
Answer:
Slope: -1
Point-Slope Form: y - 2 = -1 (x - (-2))
Step-by-step explanation:
Answer: y-2=-1(x+2)
Step-by-step explanation: use whichever points you want I’m using (-2,2)
Find slope: y2-y1/x2-x1 so 2+2/-2-2 = 4/-4 = -1
Plug in these into y-y1= m(x-x1)
y-2= -1(x+2)

How do I do this problem (similar right triangles) please explain how you did it!!
ASAP!!!
Answer:
by phythagoras theorem
(c+b)^2=(8)^2+(6)^2
(b+c)^2=64+36
(b+c)^2=100
b+c=√100
b+c=10.
by phythagoras theorem
(8)^2=(a)^2+(b)^2
64-b^2=a^2. {1}
by phythagoras theorem
(6)^2=(a)^2+(c)^2
36-c^2=a^2. {2}
In equation 1 and 2,
64-b^2=36-c^2
64-36= -c^2+b^2
28= b^2-c^2
28=(b+c)(b-c)
28=10(b-c)
b-c=28/10
b-c=2.8.
b+c=10
b-c=2.8
subtract both equations
c=3.6
option A is correct.

Jeremy spent the entire weekend earning money by working around his neighborhood 15% of his total earnings was from raking leaves and $36 mowing lawns and earn the rest of his money walking dogs the end of the weekend with earning $90 how much money did he earn by walking dogs?
Answer: $40.50
Step-by-step explanation:
Since 15% of his total earnings was from raking leaves. The earning from taking leave will be:
= 15% × $90
= 0.15 × $90
= $13.50
Earnings from mowing lawns = $36
The earnings from walking dogs will be:
= $90 - $36 - $13.50
= $40.50
two parallel lines are cut by a transversal as shown below. Suppose m<8=131. Find m<1 and m<3.
Answer:
m∠1 is 49° and m∠3 is 49°
Step-by-step explanation:
In the given figure
∵ There are 2 parallel lines
∵ A transversal cuts them
∴ ∠4 and ∠8 are corresponding angles
→ Corresponding angles are equal in measures
∴ m∠4 = m∠8
∵ m∠8 = 131°
∴ m∠4 = 131°
∵ ∠1 and ∠4 formed a pair of linear angle
∵ The sum of the measures of the linear angles is 180°
∴ m∠1 + m∠4 = 180°
→ Substitute ∠4 by 131°
∴ m∠1 + 131° = 180°
→ Subtract 131 from both sides
∵ m∠1 + 131 - 131 = 180 - 131
∴ m∠1 = 49°
∵ ∠1 and ∠3 are vertically opposite angles
∴ m∠1 = m∠3
∵ m∠1 = 49°
∴ m∠3 = 49°

Answer:

Step-by-step explanation:
(2x+1/(2x))^5 *(2x -1/(2x))^5
= ((2x)^2 -1/(2x)^2)^5 (a+b)*(a-b) =a2-b2
= (4x^2-1/4(x)^2)^5
now
x =4x^2. ,a = 1/4(x)^2 ,n =5
we have
general term = Cr *x^r *a^(n-r)
= Cr * (4x^2)^r * (1/4(x)^2)^(n-r)
= Cr *4^r * X^2r * 1/( 4^(n-r) *x^(2n-2r)
= Cr * 4^r/4^(n-r) * x^(2r)/x^(2n-2r)
= Cr * 4(2r-n) *x(4r-2n)
now for x^2
4r-2n = 2
4r -10=2
4r =12
r = 3
now for coeff
C(5,3) * 4^(2*3-5)

Katelyn was designing a cover for her binder and needed to cut some construction paper. The construction paper length can be represented by the expression (a2 + 7a - 3) if katelyn cut a piece that was (2a+5) long, how much construction paper is left
Answer:
a² + 5a - 8
Step-by-step explanation:
If the construction paper has a length of a² + 7a - 3, and Katelyn cut a piece 2a + 5 long, the amount of construction paper that would be left is,
a² + 7a - 3 - (2a + 5)
= a² + 7a - 3 - 2a - 5
collecting like terms, we have
= a² + 7a - 2a - 3 - 5
simplifying, we have
= a² + 5a - 8

In your own words, define the conic section you chose as a collection of points (loci) on a plane.
The conic section as a collection of points(loci) on a plane can be defined in this way .
What is conic section?A conic section is a curve obtained by intersecting a cone with a plane. In Algebra , There are four main types of conic sections:
circles, parabolas, ellipses and hyperbolas. Each of these conic sections has different characteristics and formulas that help us solve various types of problems.
What is loci?A locus (plural: loci) (Latin word for "place", "location") is a set of all points (commonly, a line, a line segment, a curve or a surface), whose location satisfies or is determined by one or more specified conditions.
According to the question
There are 4 main types of Conic section :
circles, parabolas, ellipses and hyperbolas. Each of these conic sections has different characteristics and formulas
Loci for circle : The locus of a circle is defined as a set of points on a plane at the same distance from the center point.
Loci for parabola : A parabola is a locus of points that are equidistance form a focus and a directrix .
Loci for hyperbola: A hyperbola is the locus of points such that the absolute value of the difference between the distances from to and to is a constant.
Loci for ellipse: An ellipse is the locus of all those points in a plane such that the sum of their distances from two fixed points in the plane, is constant. The fixed points are known as the foci (singular focus), which are surrounded by the curve.
Hence, The conic section as a collection of points(loci) on a plane can be defined in this way .

Here are two similar rectangles find the area of the largest one
Answer:
40.32 cm²
Step-by-step explanation:
The area of the small rectangle = 7 × 4 = 28 cm²
Given the ratio of the sides of similar rectangles = a : b , then
the ratio of the areas = a² : b²
Here ratio of sides = 4 : 4.8 = 1 : 1.2
ratio of areas = 1² : 1.2² = 1 : 1.44
Let x be the area of the larger rectangle then by proportion
[tex]\frac{1}{28}[/tex] = [tex]\frac{1.44}{x}[/tex] ( cross- multiply )
x = 40.32
Area of larger rectangle is 40.32 cm²
