Answer:

5

Step-by-step explanation:

let the number written on the board be x.

1st student's number= x +23

2nd student's number= x -1

1st student's number= 7(that of the 2nd student),

x +23= 7(x -1)

x +23= 7x -7 (expand)

7x -x= 23 +7 (bring constant to 1 side)

6x= 30 (simplify)

x= 30 ÷6 (÷6 on both sides)

x= 5

Thus, the number written on the board is 5.

[tex]\Large \boxed{\mathrm{\bold{B.} \ -0.5 \ ; \ 0.875 \ , \ -0.4375 \ , \ 0.21875}}[/tex]

Step-by-step explanation:

The common ratio can be found by finding the quotient of a term and the previous term in the sequence.

[tex]\displaystyle \frac{3.5}{-7} =-0.5[/tex]

The common ratio is -0.5.

The rule is to multiply a term in the sequence by -0.5 to get the next term.

Next 3 terms :

[tex]-1.75 \times -0.5=0.875 \\\\ 0.875 \times -0.5 = -0.4375 \\\\ -0.4375 \times -0.5=0.21875[/tex]

The next 3 terms are 0.875, -0.4375, 0.21875.

Answer:

b. -0.5; 0.875, -0.4375, 0.21875

Step-by-step explanation:

Given GP:

-7, 3.5, -1.75 ...

Common ratio:

r = a₂/a₁r = 3.5/-7 = - 1/2 = -0.5

Next 3 terms:

-1.75* (-0.5) = 0.8750.875*(-0.5) = - 0.4375-0.4375*(-0.5) = 0.21875

Correct answer choice is:

b. -0.5; 0.875, -0.4375, 0.21875

Answer: x=1.5

Step-by-step explanation:

The input value for which f(x) = g(x) is true is x= 1.5.

What is Function?

In mathematics, a function is an expression, rule, or law that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

We have,

The intersection both functions is the point when f(x)=g(x).

As, the point of intersection both graphs is (5, 2)

Here for the input value of x= 1.5

f(1.5)= 2

g(1.5)= 2.

Step-by-step explanation:

m=16

Answer:

Change m into 16.

m = 16

Step-by-step explanation:

So let’s start off by changing the expression to an equation.

Well let’s see to make the values equal we have to find the value of m first.

So we can set up the following equation -> [tex]2m-13=m+3[/tex].

So we have to simplify the equation to find m.

First off we want all the m’s on one side so we subtract the m on the left onto 2m and we just get m. The equation now looks like this -> [tex]m-13=3[/tex].

Now we have to get all the whole numbers on one side so we add 13 onto 3 and we get 16. Now we have [tex]m=16[/tex], so now we have to plug 16 in on the equation to see if they are equal. So we have [tex]2(16)-13=(16)+3[/tex].

Now let’s simplify it, 2*16=32-13 is 19.

Time for the next side 16+3 is 19 so m replaced as 16 makes the expressions equal.

A cylinder is a three-dimensional structure. The volume of the cylinder in cubic inches to the nearest tenth place is 1,005.3 in³.

What is a cylinder?

A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The circular bases' centers overlap each other to form a right cylinder.

The volume of the cylinder is given by the formula,

[tex]\text{Volume of the cylinder} = \dfrac{\pi}{4} d^2h[/tex]

Given that the diameter of the cylinder is 16 inches, while the height of the cylinder is 5 inches. Therefore, the volume of the cylinder,

[tex]\rm \text{Volume of the cylinder} = \dfrac{\pi}{4} \times (16^2) \times 5 = 10005.3\ in^3[/tex]

Hence, the volume of the cylinder in cubic inches to the nearest tenth place is 1,005.3 in³.

Answer:

Step-by-step explanation:

Pool:

Width = x ft

Length = (x+6) ft

Pool along with walkway:

Width = x + 5 + 5 = (x + 10) ft

Length = x + 6 + 5 + 5 = (x + 16) ft

Total area of the pool with walkway = 950 sq.ft

length * width = 950

(x+16) * (x + 10) = 950

Use FOIL method,

x*x + x *10 + 16*x + 16 *10 = 950

x² + 10x + 16x + 160 -950 = 0 {Add like terms}

x² + 26x - 790 = 0

Answer:

29.4 length and 21.4 width.

Step-by-step explanation:

To fin the dimensions of the pool we need to use the total area of the pool plus the concrete walkway. Lets say that W is the width and L the length. We know that, the walkway has 3 ft wide, this means that the width and length are increased by 6ft (3ft on each side). So, the total

Answer:

112 sheep

Step-by-step explanation:

~ If the ratio of sheep:horse is 8:3, and there are 42 horses on the farm, then that means that there are 14 times more horse than 3. Which just means that ~ 3·14 = 42

~ So we just have to take 8 (The number of sheep), and multiply it by 14, like we did to the number of horse.

~ 8 · 14 = 112

~ Now the new ratio of sheep:horse is 112:42

Answer:

The probability is found:

P = 24/3024 = 1/126

Step-by-step explanation:

To find total number of outcomes, we have to find permutation of 9 things taken 4 at a time:

P(9,4) = 9! / (9-3)!

P(9,4) =362880/120

P(9,4) = 3024

Number of even numbers from 0 to 9 = 4

To find desirable number of outcome, find permutation of 4 things taken 4 at a time.

P(4,4) = 4! / (4-4)!

P(4,4) = 24/1

P(4,4) = 24

The probability that the lock consists of all even digits is

P = No. of desirable outcomes / No. of total outcomes

Answer:

y = 1/6 x^2 + 8/3 x + 49/6

Step-by-step explanation:

This is a parabola which opens upwards.

The distance of a point (x, y) from the focus is

√[(x - -8)^2 + (y - -1)^2] and

the distance of the point from the line y = -4

= y - -4

These distances are equal for a parabola so:

√[(x - -8)^2 + (y - -1)^2] = y + 4

Squaring both sides:

(x + 8)^2 + (y + 1)^2 = (y + 4)^2

x^2 + 16x + 64 + y^2 + 2y + 1 = y^2 + 8y + 16

x^2 + 16x + 64 + 1 - 16 = 8y - 2y

6y = x^2 + 16x + 49

y = 1/6 x^2 + 8/3 x + 49/6 is the equation of the parabola.

The equation for the parabola with focus at (-8, -1) and directrix at y = -4 is (x + 8)² = 12(y + 2.5)

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The standard equation for a parabola with a vertical axis of symmetry is:

(x - h)² = 4p(y - k)

where (h, k) is the vertex of the parabola,

p is the distance from the vertex to the focus or directrix, and the sign of p depends on whether the focus is above or below the vertex.

The focus is located at (-8, -1), which is 3 units above the directrix y = -4. Therefore, the value of p is 3.

The vertex of the parabola is halfway between the focus and the directrix, so it must be at:

(h, k) = (-8, (-1 + (-4))/2) = (-8, -2.5)

Substituting these values into the equation, we get:

(x - (-8))² = 4(3)(y - (-2.5))

Simplifying, we get:

(x + 8)² = 12(y + 2.5)

Therefore, the equation for the parabola with focus at (-8, -1) and directrix at y = -4 is (x + 8)² = 12(y + 2.5)

The square root of 10 is a single number. That number is irrational, which means that its decimal expansion goes on forever without repeating, and cannot be expressed as a fraction.
