Predict the next number in the sequence: 1, 4, 16, 64…
512
244
384
256
Step-by-step explanation:
Notice that:
1 * 4 = 4,
4 * 4 = 16,
16 * 4 = 64.
Each term is 4 times of the previous term.
Hence the next term would be 64 * 4 = 256.

Answer:
19w^2-m
Step-by-step explanation:
4w^2-m+15w^2
19w^2-m
The second bracket becomes 15w^2 because it's a negative number multiplied by -1
(4w^2-m)+15w^2
19w^2-m
The angles below are supplementary, What is the value of x?
Answer:
x = 12
Step-by-step explanation:
Supplementary angles add up to 180 degrees therefore (6x + 48) and 60 should add up to 180. Like this:
6x + 48 + 60 = 180
Now solve:
6x + 48 + 60 = 180
6x + 108 = 180
6x = 72
x = 12
Therefore, the answer is x = 12.
I hope this helps!!

Find the range of the graphed function.
A. Y is all real numbers
B. Y>_0
C. 0<_y<_10
D. -9<_y<_5
Btw, <_ or >_ is the greater than or equal to or less than or equal to sign.
Answer:
The range of the function should be:
-9 ≤ y ≤ 5
Hence, option D is true.
Step-by-step explanation:
We know that the set of values of the dependent variable for which a function is defined.
From the given function, we can easily observe that the graph is kind of oscillating between the y-value y = 5 and y = -9.
i.e.
at y = 5, the graph gets its maximum value
at y = -9, the graph gets its minimum value
Thus, the range of the function should be:
-9 ≤ y ≤ 5
Hence, option D is true.

Answer:
q = 4.9
m∠R = 27.1°
m∠S = 136.9°
Step-by-step explanation:
To solve the triangle we will use the cosine rule and the sine rule
In the given triangle
∵ q is the opposite side of ∠Q
∵ s is the opposite side of ∠S
∵ r is the opposite side of ∠R
∵ m∠Q = 16°
∵ r = 8 and s = 12
→ By using the cosine rule to find q
∴ q² = r² + s² - 2 r s cos∠Q
→ Substitute the values of r, s, and ∠Q in the rule above
∵ q² = (8)² + (12)² - 2(8)(12)cos(16°)
∴ q² = 23.43775438
→ Take √ for both sides
∴ q = 4.841255455
→ Round it to the nearest tenth
∴ q = 4.9
→ To find angles R and S we will use the sine rule
∵ [tex]\frac{r}{sin(R)}[/tex] =[tex]\frac{q}{sin(Q)}[/tex] = [tex]\frac{s}{sin(S)}[/tex]
→ Use the first two ratios to find m∠R
∵ [tex]\frac{8}{sin(R)}[/tex] = [tex]\frac{4.841255455}{sin(16)}[/tex]
→ By using cross multiplication
∴ 4.841255455 × sin(R) = 8 × sin(16)
→ Divide both sides by 4.841255455
∴ sin(R) = 0.4554807874
→ Use [tex]sin^{-1}[/tex] to find m∠R
∵ m∠R = [tex]sin^{-1}[/tex] (0.4554807874)
∴ m∠R = 27.0958732
→ Round it to the nearest tenth
∴ m∠R = 27.1°
∵ The sum of the measures of the angle in a triangle is 180°
∴ m∠S + m∠Q + m∠R = 180°
→ Substitute the values of m∠Q and m∠R
∵ m∠S + 16° + 27.1° = 180°
∴ m∠S + 43.1 = 180
→ Subtract 43.1 from both sides
∴ m∠S = 136.9°

Answer:
Equation: [tex]2(x+8)+2(3x-5)+23 = 126[/tex]
[tex]x = 12.125[/tex]m
[tex]AB = 20.125[/tex]m
[tex]EF=31.375[/tex]m
Step-by-step explanation:
The equation of the perimeter of this shape can be written as:[tex]2(x+8)+2(3x-5)+23 = 126[/tex] (Sides with the same number of dashes are equal in length)
Which becomes:
[tex]2x+16+6x-10+23=126[/tex]
[tex]8x+29=126[/tex]
[tex]8x=97[/tex]
[tex]x= 12.125[/tex]
Since AB = [tex]x+8[/tex], we can substitute to get the length of AB:
[tex]x+8 = 12.125+8[/tex]
[tex]=20.125[/tex]
We can also use substitution to solve for the length of EF:
[tex]3x-5=3(12.125)-5[/tex]
[tex]=31.375[/tex]

Eddie went to Luke Base Air Force Show and brought $55 with him to spend. If admission cost him $5 and sodas were $6.25 each, what is the GREATEST number of sodas, x, Eddie can buy? USE x AS VARIABLE; NO SPACES.
Answer:
8
Step-by-step explanation:
Given that:
Eddie has gone to Luke Base Air Force Show.
Total money available with Eddie = $55
Admission cost = $5
Cost of each soda = $6.25
To find:
The greatest number of sodas that can be bought by Eddie ?
Solution:
Let the greatest number of sodas that can be bought by Eddie = [tex]x[/tex]
Now, the total money spent by Eddie will be equal to the admission fee and the cost for buying the [tex]x[/tex] number of sodas.
Cost for [tex]x[/tex] number of sodas = Cost of one soda multiplied by [tex]x[/tex] = $6.25 [tex]\times x[/tex]
Writing equation as per given statement:
Total money = $55
[tex]55 = 5 +6.25x\\\Rightarrow 6.25x = 55-5\\\Rightarrow 6.25x = 50\\\Rightarrow x = \dfrac{50}{6.25}\\\Rightarrow \bold{x = 8}[/tex]
Therefore, a maximum of 8 number of sodas can be bought.

Write an equation in slope-intercept form of the line shown.

Answer:
add 44 and 21 and you will get the answer
Answer:
y = -3/2x+2
Step-by-step explanation:
The slope for a slope equation is y = mx+b
Since it's decreasing from left to right the first part of the equation (mx) is -#x. The second part of the equation (+b) will be +2 because the y-intercept is (0,2). If it were a negative # then it would be -7, or -4, or - whatever.
Now you have to find the slope. To find the slope simply do y1-y2/x1-x2 or y2-y1/x2-x1. Let's follow this equation. say that (2,-1) is 1 and (4,-4) is 2.
-1+4/2-4 = 3/-2 = -3/2. The equation would be y = -3/2x +2. Let's check our work by substituting our variables with numbers using the set (2,-1). Pleases tell me if I'm wrong or if this is confusing.

Answer:
x = 4
y = -7 or (-7, 4)
Step-by-step explanation:
y = -2x + 1
4x + y = 9 replace y in the second equation with (-2x + 1) since y is equal to it
4x + (-2x + 1) = 9 add like terms
2x + 1 = 9 subtract 1 from both sides
2x = 8 divide both sides by 2
x = 4 since y = -2x + 1 replace x with the value we found
y = (-2) × 4 + 1 = -7

a council reviews the amount of bedrooms in 40 houses located in the same area. this table shows the information gathered
a) find the modal average of bedrooms
b) work out the mean average of bedrooms
number of bedrooms: frequency:
1 ---------------------------------5
2------------------------------- 10
3 -------------------------------15
4 --------------------------------7
5 --------------------------------3
Answer:
A. 3
B. 2.825
Step-by-step explanation:
Data obtained from the question include:
Number of bedrooms (x) > Frequency(f)
1 >>>>>>>>>>>>>>>>>>>>> 5
2 >>>>>>>>>>>>>>>>>>>> 10
3 >>>>>>>>>>>>>>>>>>>> 15
4 >>>>>>>>>>>>>>>>>>>> 7
5 >>>>>>>>>>>>>>>>>>>> 3
Mode =?
Mean average of bedrooms =.?
A. Determination of the modal average of bedroom.
The mode of a given set of data is the the value with the highest frequency.
Considering the table given in the question above, we can see clearly that 3 has the highest frequency. Hence 3 is the modal average of the bedroom is 3
B. Determination of the mean average of bedroom.
Mean = Σfx / Σf
Σfx = (1×5) + (2×10) + (3×15) + (4×7) + (5×3)
Σfx = 5 + 20 + 45 + 28 + 15
Σfx = 113
Σf = 5 + 10 + 15 + 7 + 3
Σf = 40
Mean = Σfx / Σf
Mean = 113 / 40
Mean = 2.825
Therefore, the mean average of bedroom is 2.825
