Answer:
-14
Step-by-step explanation:
Plug 3 in for x
-2 (3)² + 3 + 1
-2 (9) + 3 + 1
-18 + 3 + 1
-14
Answer:
f(3) = -14
Step-by-step explanation:
[tex]f(x)=-2x^{2} +x+1\\f(3)=-2(3)^2+3+1\\f(3) = -2(9)+4\\f(3) = -18+4\\f(3) = -14[/tex]
x/-3 is less than -10

Write the sum, and then write an equivalent expression by collecting like terms and removing parentheses whenever possible.
d. The opposite of - 10t and t - 10t
Answer:
The sum is [tex]t[/tex].
Step-by-step explanation:
Consider the provided information.
The given expression are - 10t and t - 10t
We need to find the sum of the opposite of -10 t and t - 10t.
The opposite of -10 t is 10 t.
[tex]10t+(t-10t)[/tex]
Remove the parenthesis.
[tex]10t+t-10t[/tex]
Simplify the number
[tex]10t-10t+t[/tex]
Use Additive inverse.
[tex]t[/tex]
Hence, the sum is [tex]t[/tex].
Wwhich expression uses the associative property to make it easier to evaluate 8(1/2x1/3)?
A.8/3(2x33)
B.(8x1/2)1/3.
C.8(1/3x1/2)
D.(8x1/3)1/2
The correct answer would be B. (8×1/2)1/3.
Step-by-step explanation:
8 * [(1/2) * (1/3)]
= [8 * (1/2)] * (1/3)
= 4 * (1/3)
= 4/3.
The answer is B because it is easier to calculate 8 * (1/2), which is dividing 8 by 2 to get 4.

Answer:
Through pythogoras theorem
a^2+b^2=c^2
20^2+16^2=c^2
c^2=400+256
c^2= 656
c= square root of 656
c=25.6 inches or 30 inches
Missing side 25.6 inches or 30 inches
c^2 = a^2 + b^2
c^2 = 16^2 + 20^2
c^2 = 256 + 400
c^2 = 656
Now, square root both sides to find the missing length of c or the hypontenuse.
Answer: c = 25.6 incheshelp me plz its algebra 1
Answer:
C. x > -7 and x <= 3
Step-by-step explanation:
-3 < x + 4 <= 7
Subtract 4 from the three expressions.
-7 < x <= 3
-7 < x means x > -7.
Then you have x <= 3.
Answer: C. x > -7 and x <= 3

Can SOMONE help ASAP I don’t understand the diameter of a circle plz show me how y’all got the awswer plz!!!! It’s the top one
Answer:
Step-by-step explanation:
the top one... which is I am assuming asking for the diameter?
Formula = d=2r
so 2x4 which is 8
But if you were wanting number 6
the formula is A=πr2
which would be 3.14 x 1^1 = 3.14
you take the diameter and square it and then multiply it by pi

Square ABCD has diagonals AC¯¯¯¯¯
and BD¯¯¯¯¯
. What is m∠ABD
A
180º
B
90º
C
45º
D
360º
Answer:
option (c)
Step-by-step explanation:
Given,
ABCD is a square.
AC and BD are diagonals
We know that,
Sides of the square make 90 degrees with each other.
And Diagonals bisect the opposite angles of the square.
Now,
[tex]\angle ABD = \dfrac{\angle ABC}{2}[/tex]
[tex]\angle ABC = 90^\circ[/tex]
[tex]\angle ABD = \dfrac{\angle ABC}{2}[/tex]
[tex]\angle ABD = \dfrac{90^\circ}{2}[/tex]
[tex]\angle ABD = 45^\circ[/tex]
Hence, option (c) is correct.
(5) Find the value of the variable. The diagram is not to scale.
Answer:
x = 19 degrees
Step-by-step explanation:
180 - 114 = 66
180 - 66 = 114
Other triangle angle is 114 degrees
114 + 47 = 161
180 - 161 = 19
x = 19 degrees

Complete the square x² + 16.0
Answer:
x^2 + 16x + 32
Step-by-step explanation:
I am going to guess this is from factoring.
In which you need to x's multiplied together to get x^2. So you have:
(x+?) (x+?)
to get 16x you need two 8x's in your factoring square. so it would be
(x+8) (x+8)
Now you found out what you were mulitpling together, then you solve. The final part is multiplying 8 by 8, which is 32.
