Answer:

67

Step-by-step explanation:

From the question given above, the following data were obtained:

Number of terms (n) = 12

Last term (L) = 100

Common difference (d) = 3

First term (a) =?

We can obtain the first term of the arithmetic sequence as follow:

L = a + (n – 1)d

100 = a + (12 – 1)3

100 = a + (11)3

100 = a + 33

Collect like terms

100 – 33 = a

a = 67

Therefore, the first term of the arithmetic sequence is 67

Answer:

[tex]\sqrt{61}[/tex] units

Step-by-step explanation:

We are given that

[tex]P_1=(-2,5)[/tex]

[tex]P_2=(4,0)[/tex]

We have to find the distance d (P1, P2) between the points P, and P2

We know that

Distance between  two points (x1,y1) and (x2,y2)  i

=[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Using the formula

The distance d (P1, P2) between the points P, and P2

=[tex]\sqrt{(4-(-2))^2+(0-5)^2}[/tex]

The distance d (P1, P2) between the points P, and P2

[tex]=\sqrt{(4+2)^2+(-5)^2}[/tex]

The distance d (P1, P2) between the points P, and P2

=[tex]\sqrt{6^2+25}[/tex]

The distance d (P1, P2) between the points P, and P2

=[tex]\sqrt{61}[/tex] units

Answer:

D

Step-by-step explanation:

The best way to work with fractions is to turn them into decimals by dividing the numerator by the denominator.

b

Step-by-step explanation:

smaller the number bigger the size

Answer:

56

Step-by-step explanation: Use the values of a, b, and c to find the discriminant.

Answer:

[tex]\Delta =56[/tex]

Step-by-step explanation:

We are given:

[tex]y = x^2 - 8x + 2[/tex][tex]y=x^2-8x+2[/tex]

So, a = 1, b = -8, and c = 2.

The discriminant (symbolized by Δ) is given by:

[tex]\Delta =b^2-4ac[/tex]

So, our discriminant in this case will be:

[tex]\Delta=(-8)^2-4(1)(2)=64-8=56[/tex]

Since our discriminant is a positive value, our equation has two real roots.

I think the answer is 5 (y = 5) because the lines intersection at x = -3.

Answer:

3x+12

Step-by-step explanation:

3(x+4)

Use the distributive property to multiply 3 by x+4.

3x+12

Answer:

Step-by-step explanation:

Represent the three even numbers as 2x, 2y, 2z, where x,y,z are integers.

2x+2y+2z = 108

x+y+z = 54

Let x≤y≤z

x = z/2

y = ¾z

z/2 + 3z/4 + z = 54

2z/4 + 3z/4 + 4z/4 = 54

2z + 3z + 4z = 216

9z = 216

z = 24

x = z/2 = 12

y  = ¾z = 18

The numbers are 24, 36, 48

Answer:

[tex]x = 2.5[/tex]

Step-by-step explanation:

Given

The attached figure

Required

Find x

To solve for x, we make use of the following equivalent ratio

[tex]x :3.5 = 5 : 7[/tex]

Express as fractions

[tex]\frac{x}{3.5} = \frac{5}{7}[/tex]

Make x the subject

[tex]x= \frac{5}{7}*3.5[/tex]

[tex]x= \frac{5}{2}*1\\[/tex]

[tex]x = 2.5[/tex]

Answer:

75,323,600

10.4%

292

4471

77

$2.54

Step-by-step explanation:

1. Voters in 2020 =

1.292 x 58,300,000 = 75,323,600

2.( number of turkey sandwich / total number of sandwich ) x 100

(51/491) x 100 = 10.4%

3. percent of chemistry majors = (number of chemistry majors / total students that graduated) x 100

0.017 = number of chemistry majors / 17,190

Multiply both sides of the equation by 17,190

17,190  x 0.017 = 292

4.  number of trees in 4 square miles = (4 x 1006) / 0.9 = 4471

5.  Percent from Canada = percentage of people from Canada x total number of people attending the conference

0.089 x 870 = 77

6. Average price =  total cost of items / total quantity sold

[(24 x 3.50) + (61 x0.25) + (18 x 9)] / 103 = 2.54

Answer:

Most likely answers are either 6 or 8.

Step-by-step explanation:

The sequence could be of all even numbers, so 2, 4, 6, 8, etc.

Or of all powers of 2, starting at 2, so 2, 4, 8, 16, etc.

Since there are an infinite number of sequences that fit the pattern, you just have to choose the most likely.

Step-by-step explanation:

Answer:

The answer is below.

Step-by-step explanation:

A square is a quadrilateral (has four sides and four angles) in which all the sides are equal. Also all the angle of a square are equal and measure 90°. The diagonals of a square are equal.

In square ABCD:

AB = BC = CD = AC

Given that  P, Q are the midpoints of BC, CD respectively. If AP = a and AQ = b.

a) In triangle ABP:

BC = AB (all sides of a triangle are equal)

BP = 1/2 (BC) = 1/2(AB) = 0.5AB

Using Pythagoras theorem:

AB² + BP² = AP²

substituting:

AB² + (0.5AB)² = a²

AB² + 0.25AB² = a²

1.25AB² = a²

AB² = a² / 1.25

AB² = 0.8a²

AB = √(0.8a²)

AB = a√0.8

b) In triangle ADQ:

AD = CD (all sides of a triangle are equal)

DQ = 1/2 (CD) = 1/2(AD) = 0.5AD

Using Pythagoras theorem:

AD² + DQ² = AQ²

substituting:

AD² + (0.5AD)² = b²

AD² + 0.25AD² = b²

1.25AD² = b²

AD² = b² / 1.25

AD² = 0.8b²

AD = √(0.8b²)

AD = b√0.8

c) In triangle ABD, Using Pythagoras theorem:

AB² + AD² = BD²

Substituting:

0.8a² + 0.8b² = BD²

But AB = AD (all sides of a triangle are equal). Hence AB = AD = 0.8a² = 0.8b²

BD = √(0.8a² + 0.8b²)

BD = √(1.6a²)     0.8a² = 0.8b²

BD = a√1.6

D) AC = AD (diagonal are equal)

AC = √(0.8a² + 0.8b²)

AC = √(1.6b²)     0.8a² = 0.8b²

AC = b√1.6

Answer: 2192.08

Step-by-step explanation:

6/100=0.06

1 - 0.06= 0.94

1 + 0.06= 1.06

2200*094*1.06= 2192.08

The value of the stock at the end of the second day is $2192.08.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

Value of stock = $2200

At the end of the first day →

6% decrement

6$ of 2200 ⇒ 2200 × 6/100 = 132

So,

2200 - 132 = $2068

At the end of the second day →

6% increment

6$ of 2068⇒ 2068× 6/100 = 124.08

So,

2068 +  124.08= $$2192.08

Hence "The value of the stock at the end of the second day is $2192.08".

Step-by-step explanation:

[tex] \sin(2x + 5) [/tex]

Let y = sin(z) . Where z = 2x +5

[tex]y = \sin(z) \\ z = 2x + 5[/tex]

Find the the derivatives

[tex] \frac{dy}{dx} = \cos(z) [/tex]

[tex] \frac{dz}{dx} = 2[/tex]

Multiply

[tex] \frac{dy}{dx} = \cos(z) \times 2 \\ = 2 \cos(z) [/tex]

Remember that z = 2x+5

[tex]2 \cos(2x + 5) [/tex]

The slope of the line is 1.

The slope of the line is 1 because the line moves ror goes up from left to right, making it a positive. The line also moves one block over and one block up.

a. -3

e. -3x^2 -4x +3

b 27+12-3= 36

f. 3(x+2)^2 + 4(x+2) -3

c. 27-12-3= 12

g. 3(3x)^2 + 4(3x) -3

h. 3(x+h)^2 + 4(x+h) -3

The all values of the function f(x)= 3x² + 4x - 3 are f(0) = -3 ,-f(x)  = -3x² -4x +3, f(3) = 27+12-3= 36 ,f(x + 2)=  3(x+2)² + 4(x+2) -3 ,f(-3)=  27-12-3= 12,f(3x) = 3(3x)² + 4(3x) -3,f(-x) = 3x² -4x -3,f(x + h) = 3(x+h)² + 4(x+h) -3.

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

In other words, the function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.

a) f(0) = -3

(e) -f(x)  = -3x² -4x +3

(b) f(3) = 27+12-3= 36

(f) f(x + 2)=  3(x+2)² + 4(x+2) -3

(c) f(-3)=  27-12-3= 12

(g) f(3x) = 3(3x)² + 4(3x) -3

(d) f(-x) = 3x² -4x -3

(h) f(x + h) = 3(x+h)² + 4(x+h) -3

Answer:

160

Step-by-step explanation:

Rectangle = 10x15=150

Triangle = 1/2x5x4=10

150+10=160

Step-by-step explanation:

Area of rectangle = width × length

= 10 × 15 = 150 cm²

The height of triangle = 14 - 10 = 4 cm

Area of triangle = 1/2 × base × perpendicular height

= 1/2 × 5 × 4

= 10 cm²

Area of this figure = area of rectangle + area of triangle

= 150 + 10 = 160 cm²
