So solutions of the linear quadratic systems are (-5,-3) and (1,3)

Given,

y = x²+5x -3 . . . . . . . . . .. ..1

y-x= 2 . . . . . .. . . . . . . . . . . 2\

From 1 and 2

y=x+2

substitute y=x+2 in 1

x+2= x²+5x -3

x²+5x -x-3-2 = 0

x²+4x -5=0

x²+5x-x -5=0

x(x+5) -1(x+5) = 0

(x+5)(x-1)=0

x= -5 and x=1

at x=-5

y=x+2=-5+2=-3

at x=1

y=x+2=1+2=3

So solutions of the linear quadratic systems are (-5,-3) and (1,3)

The length of UO in the rhombus is 24 inches

How to determine the length of UO?

The given parameters are

Area = 480 square inches

Diagonal RT = 20 inches

The area of the rhombus is calculated as

Area = RT * US/2

Where UO = US/2

So, we have

Area = RT * UO

So, we have

20 * UO = 480

Divide both sides by 20

UO = 24

Hence, the length of UO is 24 inches

Answer:

a) Mean

b) Median

c) Mode

Step-by-step explanation:

a) The data set has no outliers, therefore taking the average (mean) would be the best.

b) The data has outliers which would skew a mean. None of the numbers repeat, therefore mode would not work, so by process of elimination, one can find that Median is the best.

c) This data set does not have numbers, therefore mean does not make sense. The most common rating would be the rating that occurs most often, which would be mode.

20,000 ten thousands equals how many hundred thousands

Answers

20,000 ten thousand equals 2000 Hundred thousand.

As per the question statement, we are provided with a value: "20,000 ten thousand".

We are required to calculate how many hundred thousand are equal to 20,000 ten thousand.

To solve this question, let us first write down 20,000 ten thousand into the numerical format, i.e, [tex](20000*10,000)=200000000[/tex].

As we know, a hundred thousand when written down in the numerical format becomes 100,000, let us assume that 20,000 ten thousand equals to "x" number of Hundred thousand.

Therefore, we can form a linear equation in one variable "x" based on the condition, in the above-mentioned statement, which goes as  [tex](100,000*x)=200000000[/tex]

[tex]or, (100,000x)=200000000\\or,x=\frac{200000000}{100,000}\\or,x=\frac{2*10^{8} }{10^5\\}or,x=(2*10^3)\\or,x=2000[/tex]

Hence, 20,000 ten thousands equals 2000 Hundred thousands.

Linear Equation: linear equations: In Mathematics, a linear equation is an algebraic equation which when graphed, always results in a straight Line and hence comes the name "Linear". Here, each term has an exponent of 1 and is often denoted as (y = mx + c)  where, 'm' is the slope and 'b' is the y-intercept. Occasionally, it is also called as a "linear equation of two variables," where y and x are the variables.Variable: n Mathematics, a variable is a symbol or a representative of a value, which is unknown.

It follows from the task content that the line given is; y=1/4x+2.

It follows that the slope is; 1/4 by comparison with the slope-intercept equation; y = mx +c.

Since the required equation is perpendicular; it follows that the products of the slopes must be equal to; -1.

Hence, m × (1/4) = -1

m = -4.

Compute 5DBE16-9AF416 using 2’s complement, leave your final answer in octal

Answers

5DBE16-9AF416 using 2’s complement is -2635716 octal.

We need to compute 5DBE16-9AF416 using 2’s complement, leave your final answer in octal.

What is two's complement?

When two's supplement is utilized to address negative numbers, the main piece (MSB) is used to show the indication of the number. A 1 in the MSB position shows a negative number, and a 0 in the MSB position demonstrates a positive number. In two's supplement, negative numbers are addressed by the converse of the positive number in addition to 1.

To find the backwards of a number, every digit is just upset - 0 changes to 1, and 1 changes to 0. In this way, the converse of 5DBE16 is A2416. One is added to the opposite to find the two's supplements giving us A2417.

2's supplement of a number=the numbers supplement+1

5DBE16-9AF416=464416-9AF416=-54AF416+1=-54AF416

The two's supplement of a number can be determined by deducting the number from 2^n, where n is the number of pieces used to address the number. Along these lines, for this situation, we would take away 5DBE16 from 2^32, which gives us 464416.

Since the 2's complement of a number is equivalent to the negative, we can say that 5DBE16-9AF416=-54AF416.

To change over a two's supplement number to octal, we can involve a similar technique as we would use to switch a paired number over completely to the total. We bunch the pieces into three sets, beginning from the right, and convert each gathering into an octal digit.

In this way, the 2's supplements of 5DBE16-9AF416 would be composed as continues in octal 464416-9AF416=-2635716 octal

Therefore, 5DBE16-9AF416 using 2’s complement is -2635716 octal.

I have been stuck on this for the past 10 mins PLS HELP

Answers

Answer:

55°

Step-by-step explanation:

m∠D = m∠A + m∠B since for a triangle, the exterior angle = sum of interior angles

We can rewrite this as
m∠A + m∠B = m∠D

Given m∠A = (2x)°  , m∠B = (3x + 41)° and m∠D = 124° and substituting in the above equation,

2x + (x + 41.5) = 124

2x + x + 41.5 = 124

3x + 41.5 = 124

3x = 124 - 41.5 = 82.5

x = 82.5/3 = 27.5

But m∠A = (2x) = 2 x 27.5 = 55°

What is the equation of a parabola given it’s vertex?

The equation of a quadratic function, of vertex (h,k), is given by:

y = a(x - h)² + k

In which a is the leading coefficient.

For this problem, the arc has these following characteristics:

Parabolic.Concave down.The peak is at half the road.

The road under the arc is 20 feet wide with a 6-foot sidewalk on both sides of the road, hence it's total length is of 20 + 2 x 6 = 32 feet, and the peak of the arc will be at h = 16.

Hence:

y = a(x - 16)² + k.

The height is of 0 at x = 0 and x = 32, hence:

0 = 256a + k.

a = -k/256

y = (-k/256)(x - 16)² + k.

In which k is the maximum height of the arc.
