The value of f(-4) is 18 because

3(2+4)

6+12=18

When only three sides are provided without any information regarding the angle, such as a = 5 m and b = 9 m, c = 6m we can either create no triangle or create an unique triangle. Hence, either 0 or 1 Triangle.

For example :

How many different triangles may be formed with side lengths of 5m,9m and 6 m ?

Create a triangle with the following measurements: 5 meters, 9 meters , and 6meters, by protractor-adjusted to the given length of sides. You have constructed a triangle.

We can only create one triangle here, as no choice can be made in the given length of side as they are prefixed.

This implies that you cannot chose the side length independently. So, only one triangle which is unique will be formed. Hence, 0 or 1 triangle is formed

The distance between each pair of parallel lines with the given equations y = -2x+1 and y = -2x+16 is 15 units.

We can find the points passing through the lines.

Hence,

The points passing through the line y = x - 11  are:-

Let x = 0

y = -2(0) +1

(0,1)

and;

Let x = 1/2

y = -2(1/2) + 1 = -1 +1

(-1/2,0)

The points passing through the line y = -2x + 16 are:-

Let x = 0

y = -2(0) + 16 =16

(0,16)

and;

Let x = 8

y = -2(8) + 16 = -16 + 16

(8,0)

Hence, using distance formula, the distance between the parallel lines will be:-

Answer:12+2y

Step-by-step explanation:

Answer:

12 + 2y

Hope this helps :)

Step-by-step explanation:

When it says "sum," this means the answer to 2 numbers you add. The first number would be 12, and the other number will be y 2 times. So y plus y equals 2y. The final equation is 12 + 2y.

The components of the two vectors are added and subtracted to produce the addition and subtraction vector PQ. i.e. →PQ = →Q + →P and →PQ = →Q - →P

A vector, which denotes the mathematical and geometrical direction of the provided quantity, is a quantity with both magnitude and direction.

For example : Velocity, Displacement etc.  

Let's start by assuming that,

P(x,y,z) and Q(u,v,w)

Now, we need to find the vector addition and subtraction

Addition of vectors to give →PQ

→PQ = →Q + →P

= (ui + vj + wk ) + (xi + yj + zk)

= (ui + xi ) +(vj  + yj) + (wk +zk)

= (u+x) i + (v + y) j + (w + z)k

= →PQ

Similarly, Subtraction of vectors to give →PQ

→PQ = →Q - →P

= (ui + vj + wk ) - (xi + yj + zk)

= (ui + vj + wk  - xi - yj - zk)

= (ui - xi ) +(vj  - yj) + (wk -zk)

= (u-x) i + (v - y) j + (w - z)k

= →PQ

For example : Let P(1,2,1) and Q ( -1, -2,4)

Then, Addition →PQ = →Q + →P

= (1i + 2j + 1k ) + (-1i + (-2)j + 4k)

=  (1-1) i + (2 -2) j + (1 + 4)k

= oi+0j +5j

= 5j

Subtraction →PQ = →Q - →P

= (1i + 2j + 1k ) - (-1i + (-2)j + 4k)

=  (1+1) i + (2 +2) j + (1 - 4)k

= 2i+4j -3j

Hence, the vector PQ addition and subtraction is given by the addition & subtraction of the components of the two vectors.

A quadrilateral (square) may always be used to create a square in a circle. Because squares have right angles at each vertex, every pair of opposing angles in a square is complementary and inscribed in a circle. This is an unavoidable characteristic of squares.

If the form in question is a square, each pair of adjoining angles is supplementary and inscribed in a circle. This is owing to the presence of right angles at each vertex of the square. This means that the assertion can never be proven false.

Athlete swam at a constant rate, his speed in m/s is 2.343 m/s

The pace at which a distance changes over time is referred to as speed. It has a dimension of time-distance. As a result, the fundamental unit of time and the basic unit of distance are combined to form the SI unit of speed. Thus, the metre per second (m/s) is the SI unit of speed.

The formula for speed is as straightforward as dividing a distance by a time. We may define speed as the rate of change of position of an item in any direction by taking the distance traveled and dividing it by the time.

Given,

the distance covered = 50m

total time taken = 21.34s

Speed = distance / Time

speed = 50/ 21.34

By using distributive property 15(3 + 8) 15 11 = 165 both approaches yield the same conclusion.

Distrubutive Property Formula : a(b+c)=a b+a c

The distributive property is also known as the distributive law of multiplication over addition and subtraction. By its very name, the procedure implies that something will be divided or distributed.  According to the distributive property, an expression of the form A (B + C) can be resolved as A (B + C) = AB + AC. Subtraction also belongs to the scope of this distributive law, which is expressed as A (B - C) = AB - AC. The distribution of operand A among the other two operands is seen from this.

A (B + C) = AB + AC represents the distributive property of multiplication over addition.

15(3+8) = (15.3) + (15.8)

15.11 = 45 + 120

165 = 165

Using the law of BODMAS, we can now attempt to solve the expression. The solution is as follows. We will first add the figures in brackets, and then we will multiply this total by the figure outside of the brackets.

Hence, using distributive property, it follows that 15(3 + 8) x 15 = 165. As a result, both approaches yield the same conclusion.

Answer:

$3,985.00

Step-by-step explanation:

The formula for the amount accrued, A if you invest an amount P at r% compounded annually for n years is given by the formula

[tex]A = P\left(1 + \dfrac{r}{100}\right)^n[/tex][tex]A = P\left(1 + \dfrac{2}{100}\right)^{30} \\\\= P\left(1 + 0.02\right)^{30} \\\\= P\left(1 .02\right)^{30} \\\\= \; \$3,985.00[/tex]

The division by 100 is necessary to allow r% to be reduced to a decimal

In this question, we have been given an equation.

[tex]\frac{2a+1}{6}+\frac{a}{2} = \frac{a-1}{3}[/tex]

We need to find the solution of given equation.

[tex]\Rightarrow \frac{2a+1}{6}+\frac{a}{2} = \frac{a-1}{3}\\\\\Rightarrow \frac{2(2a+1)+6a}{12}=\frac{a-1}{3}\\\\\Rightarrow \frac{4a+2+6a}{12}=\frac{a-1}{3}\\\\ \Rightarrow \frac{10a+2}{4}=a-1\\\\\Rightarrow 10a+2=4a-4\\\\\Rightarrow 6a=-6\\\\\Rightarrow a=-1[/tex]

We need to check above solution.

Substitute a = -1 in LHS of given equation.

2a + 1 / 6 + a/2

= [2(-1) + 1 / 6] + [-1/2]

= (-1/6 - 1/2)

= -(4/6)

Substitute a = -1 in RHS of given equation.

a-1/3
