a positive real number is 4 less than anther of the sum of the squares of the two numbers is 72 then find the numbers.​

Answers

Answer:

3.657 and 7.657 to the nearest thousandth.

Step-by-step explanation:

x - y = 4

x^2 + y^2 = 72

From equation 1

x = y + 4 so

(y + 4)^2 + y^2 = 72

y^2 + 8y + 16 + y^2 - 72 = 0

2y^2 + 8y - 56 = 0

y^2 + 4y - 28 = 0

y = 3.657.

so x = 7.657.

You deposit $200 in a savings
account that pays a simple
interest rate of 3.25% per year.
How much interest will you earn
after 5 years?

Answers

Answer:

$32.50

Step-by-step explanation:

The equation for simple interest is

Simple Interest=P×r×n

where:

P=Principal amount

r=Annual interest rate

n=Term of loan, in years

​so

P=200

r=0.0325

n=5

so 200*0.0325*5=32.5

Help with test review homework please.

Answers

answer:
A. 11p^13
B. 10m^15

Answer:

11p^(13)

10m^(15)

Step-by-step explanation:

11×11=121 so sqrt(121)=11

Since 26/2=13, then p^(13)×p^(13)=p^(26). This implies sqrt(p^26)=p^13.

sqrt(121p^26)=11p^(13)

In short, you just find sqrt of 121 since 121 is a perfect square and then do p^(26/2) since 26 is even and be done.

solve the system x+2y-5z=10, y+2z=2, z=-1

Answers

Answer:

x=-3,y =4 z=-1

Step-by-step explanation:

x+2y-5z=10

y+2z=2

z=-1

Since z = -1, substitute into the second equation

y + 2(-1)=2

y -2 =2

y = 2+2

y=4

We can substitute into the first equation

x+2(4) -5(-1) =10

x+8+5=10

x+13 = 10

x = 10-13

x=-3

Given (x – 7)2 = 36, select the values of x.

Answers

Regroup
2(x-7)=36
Divide both sides by two
X-7= 36/2
Simplify 36/2 to 18
X-7=18
Add 7 to both sides
X=18+7
Simplify 18+7 to 25
X = 25

The values of the variable "x" which satisfy the equation (x – 7)² = 36 are x = 13 and x = 1.

To find the values of x in the expression (x - 7)² = 36, we need to solve for x using the given equation.

We Expand the square of the binomial: (x - 7)² as x² - 14x + 49,

Now, We Set up the equation as : x² - 14x + 49 = 36,

Next, We Subtract 36 from both sides: x² - 14x + 13 = 0,

Factoring the quadratic equation: (x - 13)(x - 1) = 0,

At last, Applying the zero-product property: x - 13 = 0 or x - 1 = 0,

Solving for x, We get : x = 13 or x = 1.

Therefore, The required values of "x" are x = 13 and x = 1.

Noah’s remote control car moved 12 feet in 6 seconds. Which graph has a slope that best represents Noah’s car’s average rate of speed?

Answers

We want to find a graph that represents Noah's average speed.

We define the average speed as the quotient between the distance moved and the time it takes to move that distance, then in this case we will have:

s = 12ft/6s = 2ft/s

Then we can define a linear equation:

y = (2ft/s)*x

As the distance that Noah travels in x seconds.

The graph of the given linear function can be seen below, and that is the graph with the slope that best represents Noah's average speed.

equation of the parabola in vertex form that passes through (4,-7) and has a vertex of (1,-6)

Answers

[tex]y = -\frac{1}{9}(x - 1)^2 - 6[/tex]

Step-by-step explanation:

The vertex form of the equation for a parabola is given by

[tex]y = a(x - h)^2 + k[/tex]

where (h, k) are the coordinates of the parabola's vertex. Since the vertex is at (1, -6), we can write the equation as

[tex]y = a(x - 1)^2 - 6[/tex]

Also, since the parabola passes through (4, -7), we can use this to find the value for a:

[tex]-7 = a(4 - 1)^2 - 6 \Rightarrow -7 = 9a - 6[/tex]

or

[tex]a = -\frac{1}{9}[/tex]

Therefore, the equation of the parabola is

[tex]y = -\frac{1}{9}(x - 1)^2 - 6[/tex]
