What is the value of the expression?
Answer:
-3
Explanation:
4 + 3 = 7
7² = 49
2 · 5 = 10
49 ÷ 7 = 7
7 - 10 = -3
Answer:
-3
Step-by-step explanation:
Hi!
You would get -3.
You would use Pemdas to simplify the equation.
Pemdas is parenthesis exponents multiplication division additin and subtraction in the order to do them.
First, you would do the math in the parenthesis, which equals 7.
Then, you would use the exponent which would be 7 x 7 which is 49.
Next, you would use multiplication which is 2 times 5 which is 10.
Next, you would divide, which is 49 divided by 7 which equals 7.
Now, you go from left to right which would give you -3.
Hope this helps!

Find the length of arc KN.
can a genius help me??please
Answer:
Length KN = 2π/3 = 2.094
Step-by-step explanation:
Length KN = (mKN/360)2πr
Length KN = (40/360)2π3
Length KN = (1/9)6π
Length KN = 6π/9
Length KN = 2π/3 = 2.094
If a=3i-7j and b=5i+2j, find a-b
A.2i-9j
B.2i-5j
C.8i-5j
D.8i-9j
Please explain how you solve this because i am confused
Answer:
- 2i - 9j
Step-by-step explanation:
a - b
= 3i - 7j - (5i + 2j) ← distribute
= 3i - 7j - 5i - 2j ← collect like terms
= - 2i - 9j

Find the value of x and y
Answer:
x = 45
y = 20
Step-by-step explanation:
Set the x-variables and y-variables with its corresponding ones, like so:
4x - 35 = 3x + 10
Subtract 3x from both sides:
x - 35 = 10
Add 35 to both sides:
x = 45
Solving for y:
2y - 5 = y + 15
Subtract y from both sides:
y - 5 = 15
Add 5 to both sides:
y = 20
Answer:
By vertically opposite angle
2y-5=y+15
y=20°
4x-35=3x+10
x=45°

Find the value of x and y
Answer:
x=24 y=19
Step-by-step explanation:
2y=y+19
y=19
2x-8=x+16
x=16+8
x=24
Answer:
x = 24
y = 19
Step-by-step explanation:
Set the expressions with the x-variables together, and the y-variables together, like so:
2x - 8 = x + 16
Subtract x from both sides:
x - 8 = 16
Add 8 to both sides:
x = 24
Solving for y:
2y = y + 19
Subtract y from both sides:
y = 19

Segments AB, DC and Ec intersect at point C. Angel DCE measures 148. Find the value of x.
The image is attached.
Answer:
x = 16°
Step-by-step explanation:
Segment AB, segment DC and segment EC all intersect at point C.
Here, we are told angle DCE measures 148°.
This is a semi-circle, and the total angle of a semi-circle is 180°.
Which means, x+x+148 = 180
Solving for x, we have:
x+x+148 = 180
2x + 148 = 180
2x = 180 - 148
2x = 32
[tex]x = \frac{32}{2}[/tex]
x = 16°
The value of x is 16°

In two or more complete sentences discuss the advantages and disadvantages of investing in a 529 plan versus investing in a money market account.
Answer:
Step-by-step explanation:
A 529 plan (Qualified tuition plan) is a tax-advantaged savings plan for future education costs while a money market account refers to a investment or a deposit with a financial institution that earns interest based on the current rates.
Money market deposit accounts are better choices than 529 plan for money you might need to tap at a moment’s notice to cover an emergency or an unexpectedly large expense. They pay higher interest than ordinary savings accounts and give you immediate access to your money
While in 529 savings plan, If you don’t use the money invested for college tuition, you will be penalized 10 percent when you withdraw the money to use it for something else. In addition, both your state and the federal government will tax the earnings on your account in your current tax bracket.
The basic advantage of 529 plan over money market account is the tax-advantage that is the amount invested or withdrawn is tax free. It also has high return and funds from it can be used for another beneficiary who is a qualified family member. Whereas the disadvantage is that the 529 plan is a specified fund for future education purposes. This makes it restricted as the fund can not be transferred for a different use. Unlike the money market account whose use is not restricted. It can be withdrawn to meet diverse financial needs including education. More so, funds in the money market account are insured and can be easily accessed.
In essence, the 529 plan is a specific investment while a money market account is more general in nature.

There is a line that includes point (1,2) and has a slope of 10 what is equation in intercept form
Answer:
[tex]y=10x-8[/tex]
Step-by-step explanation:
Given: Point (1,2) lies on the line such that it's slope is 10.
To find: equation of line
Solution:
Let m be the slope of line and b be the y - intercept.
Here, slope is a number that describes the direction and the steepness of the line.
y-intercept is the y-coordinate of the point where the graph of the line intersects the y-axis.
Equation of line is [tex]y=mx+b[/tex]
Put [tex](x,y)=(1,2),m=10[/tex]
[tex]2=10(1)+b\\2=10+b\\b=2-10=-8[/tex]
So, equation of line is [tex]y=10x-8[/tex]
A sporting goods company sells a tent with the dimensions shown. The company wants to introduce a new, larger tent that is geometrically similar to the original tent but with a height of 6 feet. How will the volume of the new tent compare with the volume of the original tent?
Answer:
The volume of the new tent will be 3/2 times the volume of the original
Step-by-step explanation:
The original tent is a triangular prism, which missing dimensions of the tent are:
base (b): 6 ftheight (h): 4 ftlength (l): 7 ftVolume of the original tent:
V = 1/2*b*h*l
The only difference between the new and the original tent are their heights. Let's call h' = 6 ft to the height of the new tent.
Volume of the new tent:
V' = 1/2*b*h'*l
Dividing V' by V:
V'/V = (1/2*b*h'*l)/(1/2*b*h*l)
V'/V =h'/h
Replacing with data:
V'/V =6/4
V' = 3/2*V

[tex]y = 4^x \quad \to\quad y = - \frac 2 3 (4^{x+7}) - 5[/tex]
[tex]y=4^x[/tex]
OK, we'll go in steps. First a reflection through the x axis, which negates y.
[tex]y = -4^x[/tex]
Now a vertical scaling of 2/3
[tex] y = -\frac 2 3 \cdot 4^x[/tex]
Now we shift seven units to the right,
[tex] y = -\frac 2 3 \cdot 4^{x+7}[/tex]
Now down five,
[tex] y = -\frac 2 3 \cdot 4^{x+7} - 5[/tex]
There it is.
Answer: reflection thru x axis, vertical scale 2/3, right shift 7, down 5, second choice

Find the measure of RPS
A. 45
B. 36
C. 60
D. 64
Answer:
x=8
RPS = 36
Step-by-step explanation:
QPS = 180
The two angles that form QPS
QPR + RPS = 180
7x+88 + 3x+12 = 180
Combine like terms
10x+100 =180
Subtract 100 from each side
10x = 180-100
10x = 80
Divide by 10
x =80/10
x = 8
RPS = 3x+12
= 3(8)+12
24+12
36
The triangles are congruent by SSS or HL. Triangle A B C is reflected across B C to form triangle A prime B C. Triangle A prime B C is then rotated about point A to form A prime B prime C prime.

please help!
Answer:
B 2 [tex]\sqrt[3]{3}[/tex]
Step-by-step explanation:
24 ^ 1/3
WE know that (ab) ^ c = a^ c * b*c
24 ^ 1/3 = 8^1/3 * 3 ^1/3
= 2 * 3 ^1/3
The value of equivalent expression is,
⇒ 2∛3
