Answer:
The distance is [tex]\sqrt{20}[/tex] or [tex]2\sqrt{5}[/tex].
Step-by-step explanation:
Slope of parallel: 2
Slope of perpendicular: -1/2
Pick a point for y =2x + 7. For example (0,7)
Use the perpendicular slope to get to the other line to find the other point of y=2x-3. Look at the screenshot...I got (4,5).
Distance formula [tex]\sqrt{(x_{2}-x_{1} )^{2}+(y_{2} -y_{1})^2 }[/tex]
Insert (0,7) and (4,5)
[tex]\sqrt{(0-4)^{2}+(7-5)^2 }[/tex] = [tex]\sqrt{(-4)^{2}+(2)^2 } = \sqrt{(16)+(4)} } = \sqrt{20} = 2\sqrt{5}[/tex]
The distance between parallel lines whose equations are y = 2x + 7 and y = 2x – 3 is [tex]2\sqrt{5}[/tex] and can be determined by using the point-slope form and also by using the distance formula.
Given :
y = 2x + 7y = 2x - 3First, determine the line perpendicular to the line (y = 2x + 7) whosw slope is -1/2 and intersect the line (y = 2x + 7) at point (0,7).
Using the point-slope, the equation of the perpendicular line can be determined.
[tex](y-y_1)=m(x-x_1)[/tex] ---- (1)
where m is the slope and [tex](x_1,y_1)[/tex] is the point on the line.
Now, put the value of known terms in the equation (1).
[tex]y-7=-\dfrac{1}{2}(x-0)[/tex]
y = -0.5x + 7 --- (2)
Now, determine the point of intersection between lines (y = -0.5x + 7) and (y = 2x -3).
Substitute the value of y that is (y = 2x - 3) in equation (y = -0.5x + 7).
2x - 3 = -0.5x + 7
2.5x = 10
x = 4
Now, put the value of x in the equation (y = -0.5x + 7).
y = -0.5(4) + 7
y = 5
Now, the distance between two points is given by the equation:
[tex]\rm D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]\rm D = \sqrt{(0-4)^2+(7-5)^2}[/tex]
[tex]\rm D = \sqrt{20}[/tex]
[tex]\rm D = 2\sqrt{5}[/tex]
The distance between parallel lines whose equations are y = 2x + 7 and y = 2x – 3 is [tex]2\sqrt{5}[/tex].

Claire has invested $10,000 in an 18-month CD that pays 6.25%. How much interest will Claire receive at maturity?
Answer:
the interest received is $957.03
Step-by-step explanation:
Given that
The invested amount is $10,000
There is 18 months
And, the interest rate is 6.25%
= (($10,000 × (1 + 6.25% ) × 0.0625 × 6 months ÷ 12 months)) + ($10,000 × 6.25%)
= $332.03 + $625
= $957.03
Hence, the interest received is $957.03

Answer:
A. 25 cm^3.
Step-by-step explanation:
Volume = 1/3 * area of base * perpendicular height,

= 5^3
= 25.
The correct option is A. Volume of the pyramid is 25 cm³ which is option A.
What is the volume of the pyramid?
The volume of a pyramid is given by lbh/3. It is also given by the product of the base area and height of the pyramid and then divided by 3.
The base of the pyramid is in the form of a square as all sides are 5 cm. Find the area of the square that is the base area.
5×5=25 cm²
Now multiply 25 by the height of the pyramid which is 3 cm.
25×3=75 cm³
Divide 75 by 3 to find the volume of the pyramid.
75÷3=25 cm³
Thus, the volume of the pyramid is 25 cm³ which is option A.

To represent the weight of one baseball, 0.3 pounds, Ken should shade 3
Choose...
To represent the weight of all of the baseballs, he should
shade this amount Choose... times. The shaded part of the model will represent
the expression Choose... The total weight of the baseballs is 7.3
pounds
My Progress
Answer:
2.1 pounds
Step-by-step explanation:
Given that :
Number of baseballs = 7
Weight of each baseball = 0.3 pounds
1 block = 0.1 pounds
Hence, each ball will represent 0.3 / 0.1 = 3 blocks
Hence, 3 blocks = 1 ball
7 balls will be : 3 * 7 = 21 blocks
Recall:
1 block = 0.1
Hence, 0.1 * 21 = 2.1
Therefore, the weight of the 7 balls = 2.1 pounds

Answer: [tex]\dfrac{16}{9}\ s[/tex]
Step-by-step explanation:
Given
[tex]s(t)=-t^3+2t^2+\frac{3}{2}[/tex]
Average velocity is given by
[tex]v_{avg}=\dfrac{\int vdt}{\int dt}[/tex]
[tex]v_{avg}=\dfrac{-\frac{t^4}{4}+\frac{2}{3}t^3+1.5t}{t}\\\\v_{avg}=-\frac{t^3}{4}+\frac{2}{3}t^2+1.5[/tex]
Now, equate the average and instantaneous velocity
[tex]-\frac{t^3}{4}+\frac{2}{3}t^2+1.5=-t^3+2t^2+1.5\\\\\Rightarrow -\dfrac{3t^3}{4}+\dfrac{4t^2}{3}=0\\\\\Rightarrow t^2\left(-\dfrac{3}{4}t+\dfrac{4}{3}\right)=0\\\\\Rightarrow t=\dfrac{16}{9}\ s[/tex]

2x + 2y = –2 and 3x – 2y = 12 what does x and y equal?
Answer:
(2,-3)
Step-by-step explanation:
by elemination
2x + 2y = –2
3x – 2y = 12
cross out the 2y and -2y because the cancle each other.
that leaves 2x= -2
and 3x = 12.
simply add/subtract. 2x+3x=5x
-2+12=10.
5x=10
x=2.
now for the y. we have x so all we have to do is plug.
take any equation. 2x + 2y = –2 and plug 2 into the x.
2(2)+ 2y = –2
4+2y= -2
-2-4= -6
2y=-6
y=-3.
put x and y into ordered pairs
(2,-3) and done.
easy peasy.
Answer:
x=2 y= -3
Step-by-step explanation:
2x+2y = -2
x+y = -1 (dividing both sides with 2
x+1 = -y
3x - 2y = 12
3x + (-y)(2) = 12
3x + (x+1)(2) = 12
3x+2x+2=12
5x+2=12
x=2

solve the equation 243×=73, where × is the base of the number.
The value of × that satisfies the equation 243× = 73 is approximately 0.6691.
To solve the equation 243× = 73, where × represents the base of the number, we need to determine the value of × that satisfies the equation.
We can start by rewriting the equation as an exponential equation:
243ˣ= 73
To solve for ×, we need to isolate × on one side of the equation. We can do this by taking the logarithm of both sides of the equation. Let's take the logarithm with base 10 (log) for simplicity:
log(243ˣ) = log(73)
Applying the logarithmic property, we can bring down the exponent × as a multiplier:
× * log(243) = log(73)
Now, we can solve for × by dividing both sides of the equation by log(243):
× = log(73) / log(243)
× ≈ 0.6691
Therefore, the value of × that satisfies the equation 243× = 73 is approximately 0.6691.

Answer:
the probability the octahedron will land on A is 3/8
the probability the octahedron will land on B is 1/8
the probability the octahedron will land on C is 4/8 or 1/2
Step by Step explanation:
All u have to do to figure this out is to first count the total amount of letters and in this case there are 8. To find the probability of a specific letter, you have to count how many of that letter there is in the total of 8. For example the letter A's probability is 3/8 since there are 3 A's and 8 letters in total.

Step-by-step explanation:
we can see that x=0 y= .01
so in our equation
a*bˣ
a=.01
This is throuhg plugging in 0 for x
a*b⁰=.01
a*1=.01
a=.01
Now it's just a matter of finding b
to do this just plug in a value
we know that when x=1 y=.005
.01*b¹=.005
b= .5
So our final equation is : .01*.5ˣ
