Answer:

Domain is x ∈ R

Step-by-step explanation:

There weren't any options given, but for f(x) = 2x + 15, the domain is x ∈ R.

This is because the graph is a linear function, which exists for all values of x. You can express this in lots of different ways, but R (all reals) is the conventional way to do it.

In case you don't know what a domain is: it is a set of numbers that the x-values of an equation can fit into.

Example:

f(x) = [tex]x^{2}[/tex] -> x ∈ R

This is because, if you draw a quadratic graph, you can see that the values of x are neverending.

Answer:

The missing terms are 9,13,21 and 25

The nth term is 4n + 5

Step-by-step explanation:

From the arrangement, we can see that 17 is the third term while 29 is the 6th term

Now is this sequence arithmetic or geometric?

Since it increases by the same amount each time, then it is an arithmetic sequence.

Mathematically the third term in an arithmetic sequence with first term a and common difference d is ;

a + 2d = 17 •••••(i)

While for the sixth term, we have

a + 5d = 29 ••••••(ii)

The equations are obtainable for the nth term of an arithmetic sequence which can be written as;

Tn = a + (n-1)d

where a is the first term, n is the term number and d is the common difference

Now solving both equations simultaneously;

We can subtract equation i from ii

Thus;

5d-2d = 29-17

3d= 12

d = 12/3 = 4

we can substitute the value of d in any of the equations to get a

let’s use 1

That would be;

a + 2d= 17

a + 2(4) = 17

a + 8 = 17

a = 17-8

a = 9

Now the first term is 9

Second would be 9 + 4 = 13

Fourth would be 3rd + d = 17 + 4 = 21

Fifth would be 4th + d = 21 + 4 = 25

So the sequence now correctly arranged would be;

9,13,17,21,25,29

where 9,13,21 and 25 are the missing terms

b. Mathematically the nth term of the sequence is

a + (n-1)d

let’s substitute the values of a and d , we have

9 +(n-1)4

9 + 4n-4

4n + 5

Answer: 27.33 g water

Step-by-step explanation:

For this problem, we will need to use the equation for heat: q=mCΔT. Since we are given heat, change in temperature, and specific heat, all we have to do is plug them in to find grams.

4000J=m(4.181J/g°C)(100-65°C)              [find change in temperature]

4000J=m(4.181J/g°C)(35°C)    [divide both sides by specific heat and change in temperature]

m=27.33 g

[tex]\frac{1}{18}[/tex]

Step-by-step explanation:

Given:

Flavors of ice cream are vanilla, chocolate, cookies 'n cream, strawberry, mango sorbet and mint chocolate chip.

Number of scoops can be 1, 2 or 3.

To find: probability of someone choosing cookies 'n cream ice cream with 2 scoops

Solution:

Probability refers to chances of occurrence of some event. Two events A and B are said to be independent if probability of one event does not depend on the probability of the other event.

For such events,

P(A and B)= P(A)×P(B)

Probability = number of favourable outcomes/Total number of outcomes

In the given question, cookies 'n cream ice cream with 2 scoops can be in a cone or a cup.

Therefore,

probability of someone choosing cookies 'n cream ice cream with 2 scoops =( probability of choosing cookies 'n cream ice cream × probability of having two scoops of ice-cream × probability of having ice-cream in a cup )+ (probability of choosing cookies 'n cream ice cream × probability of having two scoops of ice-cream × probability of having ice-cream in a cone )

Answer:

[tex]1156.8cm^3[/tex]

Step-by-step explanation:

The volume of a cone is given as:

[tex]V =\frac{1}{3} \pi r^2h[/tex]

where r = radius

h = height of cone

The height of the cone is 17.7 cm and its base radius is 7.9 cm (diameter is 15.8 cm).

Its volume is:

[tex]V = \frac{1}{3} * \pi = 7.9^2 * 17.7\\ \\V = 1156.8cm^3[/tex]

Answer:

1157.3cm^3

Step-by-step explanation:

voume of a cone =V=πr^2h^3

Diameter = 15.8cm

Height = 17.7cm

Radius = diameter/2

= 15.8/2 = 7.9cm

Pi = 22/7

V = 22/7 ×7.9×7.9×17.7/3

= 22/7×62.41×5.9

V = 1157.25cm^3

Hence the volume of the cone is 1157.3cm^3

the 2's cancel out on the fraction side, leaving x = -7(2)

multiply -7 and 2 to get -14

x = -14

Answer:

Step-by-step explanation:

We must find out what divided by 2 equals -7

The remainder of the equation A = 22,714 / 886 is given by R = 564

Equations are statements in mathematics that have two algebraic expressions on either side of the equals (=) sign.

It displays the similarity of the connections between the phrases on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are examples of the parts of an equation. When creating an equation, the "=" symbol and terms on both sides are necessary.

Given data ,

Let the remainder be represented as R

Let the equation be represented as A

Now , the value of A is

Let the first number be p = 22,714

Let the second number be q = 886

Now , A = p/q

On simplifying , we get

A = 22,714 / 886

886 x 25 = 22150

So , the difference between 22714 - 22150 = 564

Therefore , the value of R is 564

Hence , the remainder is 564

Step-by-step explanation:

[tex] = > 3 - 7c - 20c = 7( - 7c - 19) + 14c \\ \\ = > 3 - 27c = ( - 7c \times 7) - (7 \times 19) + 14c \\ \\ = > 3 - 27c = - 49c - 133 + 14c \\ \\ = > 3 - 27c = - 35c - 133 \\ \\ = > 3 - 27c + 35c = - 133 \\ \\ = > 3 + 8c = - 133 \\ \\ = > 8c = - 133 - 3 \\ \\ = > 8c = - 136 \\ \\ = > c = - \frac{136}{8} \\ \\ = > c = - 17[/tex]

Answer:

c = -17

Step-by-step explanation:

→Distribute the 7 to (-7c - 19):

3 - 7c - 20c = -49c - 133 + 14c

→Add like terms (-7c and -20c, -49c and 14c):

3 - 27c = -35c - 133

→Add 35c to both sides:

3 + 8c = -133

→Subtract 3 from both sides:

8c = -136

→Divide both sides by 8:

c = -17

Step-by-step explanation:

We are given the points (-2,0) and (0,2).

Slope is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{2-0}{0-(-2)}=\frac{2}{2} = 1[/tex]

The slope is one.
