4. An equilateral triangle has a perimeter of 60 cm. Find the exact
altitude of the triangle.
Step-by-step explanation:
GIVEN:-The Perimeter of Equilateral triangle = 60cm
UNDERSTANDING THE CONCEPT:-According to the question,
To find the height of the triangle,
Perimeter of Equilateral triangle = Area of Equilateral triangle.
FORMULA USED:-[tex]60 = \frac{ \sqrt{3} }{4} a {}^{2} \\ [/tex]
REQUIRED ANSWER:-[tex]60 \times 4 = \sqrt{3a {}^{2} } [/tex]
[tex]a {}^{2} = 240 \sqrt{3} \\ [/tex]

Write an expression that can be used to find the cost in dollars for b bags including shipping.
Answer:
b=21x+8
Step-by-step explanation:
she sell bags 21 dollars for every bag(x) and they only add 8 dollars 1 time
Solve for x by means of factorisation:

The triangle below is isosceles. If ∠C≅∠B, then what is BC, in units?
Answer:
Step-by-step explanation:
If angles C and B have equal degrees then the side AC is also equal to side AB in length and you can make their equations equal as well and solve for X.
2x+16=7x+6
get X's all on same side and the constants all on the other side,
-2x +2x+16=7x+6+-2x
The X's on the left cancel out.
16=5x+6
-6+16=5x+6+-6
add -6 to each side. On the right the 6 is now cancelled out.
10=5X
divide each side by 5 to cancel out the 5
10/5= 5X/5

4x-3y=15
(Worth 10 points )
A:1/2
B: -1
C:3/4
D:-2/3
Answer:
[tex]m = -\frac{2}{3}[/tex]
Step-by-step explanation:
Given
[tex]2x+3y=12[/tex]
[tex]4x-3y=15[/tex]
Required
Slope of #1
[tex]2x+3y=12[/tex]
Make y the subject
[tex]3y = -2x + 12[/tex]
Divide through by 3
[tex]y = -\frac{2}{3}x + \frac{12}{3}[/tex]
[tex]y = -\frac{2}{3}x + 4[/tex]
An equation has the form:
[tex]y = mx + c[/tex]
Where
[tex]m = slope[/tex]
Compare [tex]y = mx + c[/tex] and [tex]y = -\frac{2}{3}x + 4[/tex]
[tex]m = -\frac{2}{3}[/tex]
Hence, the slope is [tex]-\frac{2}{3}[/tex]

What is sine rule?Law of Sines In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.
The formula for sine rule is sinA/a=sinB/b=sinC/c
From the given triangle VWX, ∠X=51°, ∠W=16° and VW=x=14.
Here, sinX/x=sinW/w
sin51°/14=sin16°/w
0.7771/14=sin16°/w
0.7771/14=0.2756/w
0.0555=0.2756/w
w=0.2756/0.0555
w=4.965
w≈5
Therefore, option D is the correct answer.

Enter the value of b when the expression 9x + b is equivalent to
3(3x + 1).
BE
ker notes
Answer:
b = 3
Step-by-step explanation:
Isolate the variable, b. Note the equal sign, what you do to one side, you do to the other:
First, distribute 3 to all terms within the parenthesis:
3(3x + 1) =
3 * 3x = 9x
3 * 1 = 3
9x + b = 9x + 3
Isolate the variable, b. Subtract 9x from both sides:
9x (-9x) + b = 9x (-9x) + 3
b = 3
3 is your value for b.

WILL MARK BRAINLIEST - One factor of the function f(x)=x^3-8x^2+17x-10 is (x-5). Describe how to find the x-intercepts and y-intercept of the graph of f(x) without using technology. Show your work and include all intercepts in your answer.
Answer: x-intercepts (5,0), (2,0), (1,0)
y-intercept (0,-10)
Step-by-step explanation: If one factor of the polynomial function is (x-5), then the function f(x) can be factored in the following way: (x-5) (x^2-3x+2)
Now factor the trinomial: (x-2) (x-1)
Thus, x-intercepts (points where f(x)=0) are
x1=5
x2=2
x3=1
and y-intercept (point where x=0) is
f(0)=0^3-8.0^2+17.0-10=-10.

A function assigns the values. The y-intercept of the function is -10, while the x-intercept of the function is 5, 2, and 1.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
To find an intercept of the function, we need to substitute the value of x or y depending on the intercept as 0 in the function. Therefore, the x-intercept of the function is,
y = (0)³ - 8(0)² + 17(0) - 10
y = -10
Since given that one factor of the function f(x)=x³-8x²+17x-10 is (x-5). Therefore, if the function f(x) is divided by (x-5). The quotient will be x²-3x+2.
Now, Factorising the given expression x²-3x+2.
x²-3x+2
= x² - 2x - x + 2
= x(x-2) -1(x-2)
= (x-2)(x-1)
Now, we can write the function f(x)=x³-8x²+17x-10 as y=(x-5)(x-2)(x-1). Therefore, the x-intercept of the function is,
x-intercept = 5, 2, 1
This can be verified from the graph formed below.
