What is the cubic root of 81 without a calculator? And how do you get it? Please explain
Answer:
[tex] 3\sqrt[3]{3} [/tex]
Step-by-step explanation:
First, notice that 81 is divisible by 3.
81/3 = 27
27 is also divisible by 3.
27/3 = 9
9 = 3 * 3
81 = 3 * 3 * 3 * 3
81 = 3^3 * 3
[tex] \sqrt[3]{81} = \sqrt[3]{3^3 \times 3} = 3\sqrt[3]{3} [/tex]

Triangle ABC is reflected across the line y=2x to map onto triangle RST. Select all statements that are true.
AB = RS
AB = 2RS
ABC ~ RST
ABC = RST
m<BAC = m<SRT
m<BAC = 2m<SRT
The reflection transformation in the question is a rigid transformation,
therefore, the image and the preimage are congruent.
The statements that are true are;
AB = RS∠ABC ~ ∠RSTΔABC = ΔRSTm∠BAC = m∠SRTReasons:
The given parameter are;
Triangle ΔABC is reflected across the line 2·X, to map onto triangle ΔRST
Required:
To select the true statements
Solution:
A reflection is a rigid transformation, therefore, the distance between corresponding points on the image and the preimage are equal.
Therefore;
AB = RS
BC = ST
AC = RT
Given that the image formed by a reflection is congruent to the preimage, we have;
ΔABC ≅ ΔRST
∠ABC ≅ ∠RST
m∠ABC = m∠RST by the definition of congruency
∠BCA ≅ ∠STR
m∠BCA = m∠STR by the definition of congruency
∠BAC ≅ ∠SRT
m∠BAC = m∠SRT by the definition of congruency

hi, can anyone help with b) and c)?
Answer:
steps below
Step-by-step explanation:
From the graph: parabola pass (0,4) (3,4) (1,2)
equation: y = ax² + bx + c
(0,4): c = 4
(3,4): 9a + 3b + 4 = 4 9a+3b = 0 3a + b = 0 ... (1)
(1,2): a + b + 4 = 2 a+b = -2 ... (2)
(1)-(2): 2a = 2 a = 1
(2): b = -3
parabola equation: f(x) = x² - 3x +4
(a) f(3) = 3² - 3*3 + 4 = 4
(b) normal line: parallel to tangent line y = 3x -5 at (3,4)
slope of line N: -1/3 pass (3,4)

Find the measure of the missing angles
Answer:
m∠1 = 63
m∠2 = 49
m∠3 = 87
m∠4 = 44
Step-by-step explanation:
Angle 2 and 49 are similar
Angle 2 = 49
Angle 1 + 49 + 68 = 180
180 - 49 - 68 = Angle 1
180 - 49 - 68 = 63
Angle 1 = 63
Angle 3 + 93 = 180
180 - 93 = Angle 3
180 - 93 = 87
Angle 3 = 87
Angle 4 + 49 + 87 = 180
180 - 49 - 87 = Angle 4
180 - 49 - 87 = 44
Angle 4 = 44
Step-by-step explanation:
A straight angle measures 180°.
m∠3 = 180 - 93
m∠3 = 87
The sum of the three angles of any triangle is equal to 180°.
m∠4 = 180 - (49 + 87)
m∠4 = 180 - 136 = 44
The vertically opposite angle.
so m∠2 = 49
The sum of the three angles of any triangle is equal to 180°.
m∠1 = 180 - (68 + 49)
m∠1 = 180 - 117 = 63

Im not sure how to do this
Answer:
see explanation
Step-by-step explanation:
Since the figures are similar then then corresponding sides are in proportion , that is
[tex]\frac{NP}{ST}[/tex] = [tex]\frac{NM}{SR}[/tex] , substitute values
[tex]\frac{x}{25}[/tex] = [tex]\frac{18}{30}[/tex] ( cross- multiply )
30x = 450 ( divide both sides by 30 )
x = 15
Similarly
[tex]\frac{UT}{QP}[/tex] = [tex]\frac{NM}{SR}[/tex] , that is
[tex]\frac{y}{15}[/tex] = [tex]\frac{18}{30}[/tex] ( cross- multiply )
30y = 270 ( divide both sides by 30 )
y = 9
The similarity ratio is the ratio of corresponding sides , that is
[tex]\frac{NM}{SR}[/tex] = [tex]\frac{18}{30}[/tex] = [tex]\frac{3}{5}[/tex]
SRUT is [tex]\frac{3}{5}[/tex] of NMQP

Solve for b in the literal equation a+ b+ c= 180
Answer:
b = 180 - a - c
Step-by-step explanation:
To solve for b given the literal equation, a + b + c = 180:
Subtract a and c from both sides:
a + b + c = 180
a - a + b + c - c = 180 - a - c
b = 180 - a - c

Write the equation of the line in point-slope form.
Answer:
y-1= -3/4(x-1)
Step-by-step explanation:
find the slope then put it in the format: y2-y1=m(x2-x1)
y-1= -3/4(x-1)
Answer:
y = -3/4x + 7/4
Step-by-step explanation:
So we have 2 points:
(-3, 4) & (1, 1)
The formula for point-slope is:
y - y1 = m (x - x1)
First, we need to find the slope between the points
The formula for this is
(y2 - y1) /(x2 - x1)
1 - 4 / 1 - (-3) ->
-3 / 4
Our slope is -3/4 (m)
y = -3/4 (x + 3) + 4
I've done this using a simplified formula for point slope which is
y = m(x - x1) + y1
we can simplify this equation more
y = -3/4x + 7/4
is our final equation.
What is the expression in factored form?
4x2 +11x+6
O (2x+3)(2x+2)
O (4x+1)(x+6)
O (2x+1)(2x+6)
(4x+3)(x+2)
Answer: (4x + 3) (x + 2)
Step-by-step explanation:
We can rewrite 4x² + 11x + 6 as 4x² + 8x + 3x + 6
Since 4x² + 11x + 6 = 4x² + 8x + 3x + 6
= (4x + 3) (x + 2)
The factors of the given expression [tex]4x^2 +11x+6[/tex] are (x+8) and (x+3).
A collection of constants, variables connected using one or more arithmetic operator is called an expression.
An algebraic expression or a number that divides another number without leaving any remainder and the quotient is a whole number is called a factor.
The factors of the following expression can be calculated as:
[tex]4x^2 +11x+6[/tex] = [tex]x^2+ 8x+ 3x+24[/tex]
= x(x+8) +3(x+8)
= (x+8) (x+3)
Thus, the factors of the [tex]4x^2 +11x+6[/tex] are (x+8) (x+3)

the sum of the measures of the angles of all triangles is 180 degrees.if one angle of the triangle measures 45 degrees,and other two angles are equal.what is the measure of the other two angles?
Answer:
67.5 degrees.
Step-by-step explanation:
Let the measure of two equal angles of the triangles is x.
Thus, the angles of the triangles are x, x and 45 degrees.
Answer:
67.5°
Step-by-step explanation:
Given:
All triangles is 180°
One Triangle measure 45°
2 Other Angles are equal
To Find:
Two Other Angles
Solution:
180°- 45° = 135°
135° ÷ 2 = 67.5°
Therefore the other two angles are 67.5°
