f(x)=2x^2 find f(-3)
Answer:
f(- 3) = 18
Step-by-step explanation:
Substitute x = - 3 into f(x) , that is
f(- 3) = 2(- 3)² = 2(9) = 18
What is the probability of rolling a number less than 4 on a number cube?
Answer:
1/2, 50%
Step-by-step explanation:
A cube has six sides. The probability of landing on a number less than four is 3/6 because there are 3 positive numbers less than 4. 3/6=1/2=50%

find the value of the letter and number below
[tex]a_4[/tex]
Answer:
a4 = 123
Step-by-step explanation:
Here, we want to find the value of the 4th term
we simply have n as 4
substituting this, we have;
a4 = (a3)^2 + 2
But a^3 = (a2)^2 + 2 and
so we have ;
a4 = [(a2)^2 + 2]^2 + 2
But a2 = (a1)^2 + 2
a4 = {[(a1)^2 + 2)]^2 + 2}^2 + 2
Now, substitute the value of a1
a4 = (1)^2 + 2)^2 + 2)^2 + 2
a4 = (1 + 2)^2 + 2)^2 + 2
a4 = (3^2 + 2)^2 + 2
a4 = 11^2 + 2
a4 = 121 + 2
a4 = 123
Morgan uses 1/5 of her supply of raisins to make trail mix and 3/10 of her supply to make cookies. If Morgan uses 5 pounds of raisins, how many pounds of raisins are in her supply? O. 5 pounds. O. 8 pounds O. 12 pounds O. 15 pounds
Answer:
8 pounds
Step-by-step explanation:
x represents the starting amount
5 = 3x/8 + x/4
40 = 3x + 2x multiply both sides by LCD, 8
40 = 5x
x=8
Can someone help me plzzzz
Answer:
279 feet
Step-by-step explanation:
To find x, we solve using the Trigonometric function of Tangent
tan θ = Opposite/ Adjacent
θ = 64°
Length of the shadow = Adjacent = 136 feet
Height of the building = Opposite = h
Hence,
tan 64 = h/136 feet
Cross Multiply
h = tan 64 × 136 feet
h = 278.84132245 feet
Approximately, h to the nearest foot ≈ 279 feet
Therefore, the height of the building = 279 feet

Answer:
17.) 12
18.) 1/15
Step-by-step explanation:
2 ÷ [tex]\frac{1}{6}[/tex]
This problem is asking how many [tex]\frac{1}{6}[/tex] 's can go into 2 blocks. If you divide one box into 6 parts, each tiny box will be [tex]\frac{1}{6}[/tex] of the whole. Divide the other box into 6 parts as well, and you will get 12 of these [tex]\frac{1}{6}[/tex] parts. Check your answer by multiplying 12 by [tex]\frac{1}{6}[/tex]. The answer is [tex]\frac{12}{6}[/tex] which is also equal to 2.
[tex]\frac{1}{3}[/tex] ÷ 5
For this one, think of it as we have one big box divided into thirds. We want to divide each [tex]\frac{1}{3}[/tex] portion by 5. So you should have 5 tiny boxes in each [tex]\frac{1}{3}[/tex] which gives you a total of 15 boxes. But if we look at it as one big box divided into 15 parts, we know that each of those is [tex]\frac{1}{15}[/tex]. Check your answer by multiplying [tex]\frac{1}{15}[/tex] by 5 and you get [tex]\frac{5}{15}[/tex] which is equal to [tex]\frac{1}{3}[/tex].
Let me know if you have any questions, and good luck!

What is the percentage increase of R20 to R22.
Answer: 10%
Step-by-step explanation: R20 = 100
Therefore R1 = 100%÷ R20 = 5%. The difference between R22 and R20 is R2, therefore the increase in % is R2×5%=10%.
Answer:

Find the nth term of the quadratic sequence
Answer:
x^2
Step-by-step explanation:
all the numbers are square roots so n square is the nth term.
2^2= 4
3^2=9
4^2=16
5^2=25
6^2=36
Answer:
[tex] {n}^{2} [/tex]
Step-by-step explanation:
Drawing number into triangular dot pattern and making a square (with same numbers of dots in rows and columns) will give a square number. Similarly, 16 = 42 = 32 + (3 + 3 + 1), 25 = 52 = 42 + (4 + 4 + 1) and so on.
help me plzzzzzzZZZZZZZZZ
Answer:
20
Step-by-step explanation:
We know that the diagonals are bisected, which means
2x+4 = 6x-8
Subtract 2x from each side
2x+4-2x = 6x-8-2x
4 = 4x -8
Add 8 to each side
4+8 = 4x-8+8
12 = 4x
Divide by 4
12/4 = 4x/4
3 =x
We want to know CF = DB = 2x+4 + 6x -8
CF = 8x-4
= 8(3) -4
= 24-4
= 20

What is 15/5 simplified?
Answer:
3
Step-by-step explanation:
fractions are division, so if you divide the numerator by the denominator you'll always get the mixed number / whole number
so 3/4 is equal to 3 divided by 4
15 divided by 5 is 3, because 3 x 5 = 15

The piecewise defined function f(x) is graphed below. What is the value of f(5)?
================================================
Explanation:
Draw a vertical line through 5 on the x axis. This represents the equation x = 5. Notice that we intersect the blue line at (5,-1) which tells us that f(5) = -1. There's a closed point here, meaning that the point is included. This is in contrast to the open hole at (5,3) which is not part of the function. So be careful not to say that f(5) = 3 because that's not the case.
Answer:
i think it's f(5) - a wild guess

Find the value of x.
a
x = 104
b
x = 72.5
c
x = 166
d
x = 93.5
Answer:
x=104
Step-by-step explanation:
Angle Formed by Two Secants= 1/2(difference of Intercepted Arcs)
10.5 = 1/2( x-83)
Multiply each side by 2
2* 10.5 = 2*1/2( x-83)
21 = x-83
Add 83 to each side
21+83 = x-83+83
104 =x
