Answer:

Domain (-2,3)

Range (-10, 20)

Function: Definitely

Step-by-step explanation: So check it right. Starting with Domain how far do our values go in the x direction positive and negative in this case the farthest to the left is -2 and to the right is 3. For range same thing but now we look at the y axis -10 is lowest and 20 is the highest. Open circles don't affect our domains or range but they are important for determining functions. This is a function because going up and down the graph vertically at any points doesn't collide with any point more than once. If the open circle were closed then this would not be a function but in this case it is a function.

Answer:

Slope is 4.

Step-by-step explanation:

First, we need to find two points in order to find the slope.

Point A (50, 0)

Point B (60, 40)

Next, we have to plug the points in to the slope equation.

[tex]m = \frac{y_{2} - y{1}}{x_{2}- x_{1}}[/tex]

Point A will be [tex](x_{1}, y_{1})[/tex]

Point B will be [tex](x_{2}, y_{2})[/tex].

[tex]m = \frac{40 - 0}{60- 50}[/tex]

[tex]m = \frac{40}{10}[/tex]

[tex]m = 4[/tex]

Therefore, the slope is 4.

Answer:

x = 5    y = -13

Step-by-step explanation:

5(5) - 3 = 22 and 5 - (-13) = 18

The value of x and y is △ABC ≅ △DEF are 5 and -13 respectively

Since △ABC is congruent to △DEF. hence all the sides of △ABC will be equal to △DEF.

Given the sides of △ABC to be 18, 25, and 5x − 3.

Sides of △DEF to be 25, 22, and 5 − y

This shows that the third side of triangle △ABC is 22, hence

5x - 3 = 22

5x = 22 + 3

5x = 25

x = 5

Similarly, the thirs side of △DEF will be 18, hence;

5 - y = 18

y = 5 - 18

y = -13

Hence the value of x and y is △ABC ≅ △DEF are 5 and -13 respectively

Answer:

Step-by-step explanation:

in the formula given.  Asin(Bx)    the A does mean Amplitude and the Bx is how fast the function repeats... and b/c sin is a function of pi  (π)  then if we want it to repeat every 2 of x  then.. we do need to know the units of X .... but.. here it's just a number.. so we have to add the pi part.. b/c sin repeats every 2pi.... sooo....we are told that it's supposed to have an Amplitude of 3.... just how tall is the highest peak of the sin wave... so that's A = 3 .. and to repeat each time x gets to a multiple of 2.. like 2,4,6, ... ect.

so we have to add the pi part...  so that each time x gets to 2 .. the function starts over.  :/  this sounds confusing to me.. even as I explain it.. :/

Answer:

The answer is 34

Step-by-step explanation:

The ratio of AD:EH is 1:2, so therefore the other line segments have the same ratio. Using this logic, we see that DC is equal to 17 m, and we need to find GH. All we do now is double the measurement of DC since the ratio of the two shapes is 1:2.

Therefore, 17 * 2 = 34

Answer: [tex]1250\ m^2[/tex]

Step-by-step explanation:

Let x= Total land.

Then for Maize = [tex]\dfrac{x}{3}[/tex]    

For Potatoes = [tex]\dfrac15(x-\dfrac {x}{3})=\dfrac15(\dfrac{2x}{3})=\dfrac{2}{15}x[/tex]

For beans = [tex]x- (\dfrac{x}{3}+\dfrac{2}{15}x)=0.5 \ ha[/tex]

[tex]\Rightarrow\ x- (\dfrac{5x+2x}{15})=0.5 \ ha\\\\\Rightarrow\ x- (\dfrac{7x}{15})=0.5 \ ha\\\\\Rightarrow\ \dfrac{15x-7x}{15}=0.5 \ ha\\\\\Rightarrow\ \dfrac{8x}{15}=0.5 \ ha\\\\\Rightarrow\ x=0.5\times\dfrac{15}{8} \ ha\\\\\Rightarrow\ x=0.9375 \ ha[/tex]

1 ha = 10000.00 m²

0.9375 ha = 9375 m²

Land for potatoes = [tex]\dfrac{2}{15}(9375) =1250\ m^2[/tex]

Hence, [tex]1250\ m^2[/tex] of the land is on potatoes.

Answer:

nth term = 6n + 4 where n = no. of terms.

I hope it will be useful.

Answer:

[tex]a_{n}[/tex] = 6n + 4

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 10 and d = a₂ - a₁ = 16 - 10 = 6, then

[tex]a_{n}[/tex] = 10 + 6(n - 1) = 10 + 6n - 6 = 6n + 4

Answer:

Ana is correct

Step-by-step explanation:

Given

[tex]Sequence:\ -10, -4, 2,8[/tex]

[tex]Carlos; f(n) = -10 + 6n[/tex]

[tex]Ana; f(n) = -10 + 6(n-1)[/tex]

Required

Determine who is right?

To do this, we simply test each sequence.

For Carlos:

When n = 1

[tex]f(1) = -10 + 6 * 1 = -10 + 6 = -4[/tex]

When n = 2

[tex]f(2) = -10 + 6 * 2 = -10 + 12 = 2[/tex]

This is incorrect because the first and second term of the sequence are -10 and -4 not -4 and 2

For Ana:

When n = 1

[tex]f(1) = -10 + 6(1-1) = -10 + 6*0 = -10 + 0 = -10[/tex]

When n = 2

[tex]f(2) = -10 + 6(2-1) = -10 + 6*1 = -10 + 6 = -4[/tex]

When n=3

[tex]f(3) = -10 + 6(3-1) = -10 + 6*2 = -10 + 12 = 2[/tex]

When n = 4

[tex]f(4) = -10 + 6(4-1) = -10 + 6*3 = -10 + 18 = 8[/tex]

This is correct.

Hence, Ana is correct

we are to find: the probability that the number of U.S. adult who thinks that the government should help fight childhood obesity is:

(a) exactly two  (b) at least four

Answer:

P(X =2) = 0.3160

P(X  ≥ 4) = 0.1656

Step-by-step explanation:

From the given information:

The population proportion = 39/100 = 0.39

the sample size = 6

(a) The required probability that exactly two adults fight childhood obesity out of the six is:

[tex]P(X=2) = (^6_2) (0.39)^2 (1-0.39)^{6-2}[/tex]

[tex]P(X=2) = \dfrac{6!}{2!(6-2)!} (0.39)^2 (1-0.39)^{4}[/tex]

[tex]P(X=2) = 15 \times 0.1521 \times 0.1385[/tex]

P(X =2) = 0.3160

(b)

The probability that at least 4 adults did is:

P( X ≥ 4) = P(X = 4) + P(X = 5) + P(X = 6)

[tex]P( X \ge 4) =(^6_4) (0.39)^4 (1-0.39)^{6-4} + (^6_5) (0.39)^5 (1-0.39)^{6-5}+ (^6_6) (0.39)^6 (1-0.39)^{6-6}[/tex]

[tex]P( X \ge 4) =(\dfrac{6!}{4!(6-4)!}) (0.39)^4 (1-0.39)^{2} +(\dfrac{6!}{5!(6-5)!}) (0.39)^5 (1-0.39)^{1}+ (\dfrac{6!}{6!(6-6)!}) (0.39)^6 (1-0.39)^{0}[/tex]

P(X  ≥ 4) = 0.1291 + 0.0330 + 0.0035

P(X  ≥ 4) = 0.1656
