you find a triangle that has an area of 10 sq ft. the height of the triangle is 10 feet. what is the length of the base of the triangle?
Answers
Solution:
Given :
Area of triangle = 10 ft² Height of triangle = 10 ftSo, We have to find the Base of Triangle .
Area of triangle = 1/2*b×h, Where represents
B represent Base H represent HeightStep : Substitute those value in Formula;
Area of triangle = 1/2 × b × h
10 = 1/2 × b × 11
20 = 11 × b
b = 20/11
b = 1.81 ft
Therefore, Base of Triangle is 1.81 ft
Final answer:
To find the base of a triangle with an area of 10 sq ft and a height of 10 ft, use the formula 1/2 × base × height. By rearranging the formula and substituting the known values, the base is calculated to be 2 feet.
Explanation:
The question is asking to find the length of the base of a triangle when the area is 10 square feet and the height is 10 feet. The formula for the area of a triangle is 1/2 × base × height. In this case, we know the area (10 sq ft) and the height (10 ft), and we need to solve for the base.
Inserting the known values into the formula gives us:
Area = 1/2 × base × height
10 = 1/2 × base × 10
To solve for the base, we rearrange the formula:
base = 2 × Area / height
base = 2 × 10 / 10
base = 2 feet
Therefore, the length of the base of the triangle is 2 feet.

Answers
Answer:
[tex]\lim_{x \to 0}\ x^2 -2 = -2[/tex]
Step-by-step explanation:
We have the following limit
[tex]\lim_{x \to 0}\ x^2 -2[/tex]
To solve this limit using direct substitution to substitute the value that tends x into f(x) and simplify.
In this case x tends to zero, then we substitute x = 0 in the function and simplify
[tex]\lim_{x \to 0}\ x^2 -2= (0)^2 -2= -2[/tex]
Therefore
[tex]\lim_{x \to 0}\ x^2 -2 = -2[/tex]
When x approaches 0 then f(x) it tends to -2

Answer:
The red line is g(x)
Step-by-step explanation:
* To solve this problem you must to know some fact about
transformation
- If the function f(x) translated horizontally to the left
by h units, then the new function g(x) = f(x + h)
- If the function f(x) translated vertically up
by k units, then the new function g(x) = f(x) + k
- If the function f(x) translated vertically down
by k units, then the new function g(x) = f(x) – k
- A vertical stretching is the stretching of the graph away from
the x-axis
• if k > 1, the graph of y = k•f (x) is the graph of f (x) vertically
stretched by multiplying each of its y-coordinates by k.
- A vertical compression is the squeezing of the graph toward
the x-axis.
• if 0 < k < 1 (a fraction), the graph is f (x) vertically compressed
by multiplying each of its y-coordinates by k.
• if k should be negative, the vertical stretch or compress is
followed by a reflection across the x-axis.
* Now lets solve the problem
- g(x) = -1/2f(x + 2)
# x + 2 ⇒ means the graph moved 2 units to the left
# -1/2 ⇒ means the graph has vertical compressed followed
by a reflection across the x-axis, then multiply
each y-coordinate by -1/2
- The graph of f(x) intersects x-axis at point (3 , 0)
∴ The point will be (1 , 0) on g(x)
- The graph of f(x) intersects y-axis at point (0 , -6)
∴ The point will be (-2 , 3) on g(x)
* Look to the graph
# The red line is g(x)
# The blue line is f(x)
- To check your answer
# The equation of f(x) is f(x) = 2x - 6
∵ g(x) = -1/2f(x + 2)
∴ g(x) = -1/2[2(x + 2) - 6] = -1/2[2x + 4 - 6] = -1/2[2x - 2] = -x + 1
* g(x) intersect x-axis at point (1 , 0) and y-axis at point (0 , 1)
suppose that F(x)=x^3 and G(x)=-2x^3
Answers
Answer:
A
Step-by-step explanation:
Given a function f(x) = x^2, we can say:
g(x) = -(x^2) is the reflection of f(x) in the x-axish(x) = ax^2 is a vertical stretch if a > 1 and a vertical compression if 0 < a < 1The negative sign in front says that G(x) is flipped over the x-axis with respect to F(x). Also, the 2 in front tells us that it is a vertical stretch of the function F(x), since a > 1.
Hence, answer choice A is right.

Simplify the expression 3x(x – 12x) + 3x2 – 2(x – 2)2. Which statements are true about the process and simplified product?
Answers
Simplifying the expression requires expanding the brackets, combining like terms, and applying algebraic rules including distribution. The resulting simplified form is – 35x2 + 8x – 8 after properly eliminating unnecessary terms and ensuring the solution is valid.
Explanation:To simplify the expression 3x(x – 12x) + 3x2 – 2(x – 2)2, we need to apply standard algebraic techniques such as distribution, combining like terms, and simplifying polynomial expressions.
Firstly, distribute the 3x across the parentheses: 3x×(x – 12x) becomes 3x2 – 36x2.
Then, expand the square: – 2(x – 2)2 becomes – 2(x2 – 4x + 4).
Next, we can simplify the expression by combining like terms and further distributing where necessary:
3x2 – 36x2 + 3x2 – 2x2 + 8x – 8Combine like terms:
– 35x2 + 8x – 8Eliminate terms wherever possible and check to see if the simplified expression is reasonable. We are using multiplication, distribution, and combination of like terms to simplify the algebraic expression.
Find the surface area of the regular hexagonal prism. Round your answer to the nearest hundredth.
Answers
Answer:
860.55 mm²
Step-by-step explanation:
The surface area of an hexagonal prism, also known as an octahedron, is given by the following formula (since we have the apothem):
S= 6*b*(a+h)
where b = is the side of the base, a is the apothem length, and h = the height
S = 6 * 8 * (4√3 + 11) = 48 * 17.92812 = 860.55 sq mm
Could have also have used another formula without the apothem:
S =3 * √3 * b² + 6 * b * h
S = 3 * √3 * 8² + 6 * 8 * 11 = 3√3 * 64 + 528 = 332.55 + 528 = 860.55 sq mm

kate has 2/3 yards of fabric to make small flags each flag requires 1/6 yards of fabric how many flags cane kate make
Answers

THE ANSWER IS 7
Step-by-step explanation:
CAUSE UR MOM IS A TRASHIE i'm sorry i meant YO MAMA
Final answer:
Kate can make 4 small flags from 2/3 yards of fabric since each flag requires 1/6 yards of fabric.
Explanation:
Kate has 2/3 yards of fabric and each small flag requires 1/6 yards of fabric. To find out how many flags Kate can make, you divide the total amount of fabric by the amount needed for one flag:
2/3 yards \/ 1/6 yards = 4 flags.
Here's the step-by-step calculation:
First, recall that dividing by a fraction is the same as multiplying by its reciprocal. In this case, the reciprocal of 1/6 is 6/1.
So, multiply 2/3 by the reciprocal of 1/6:
2/3 × 6/1 = 12/3 = 4.
Thus, Kate can make 4 small flags from the fabric she has.

You need to remember that a product is the result of a multiplication.
Let be the number mentioned in the problem "x", "the product of seventeen and a number" means that:
[tex](17)(x)=17x[/tex]
Now "twelve more than the product of seventeen and a number" indicates that you need to add 12 to [tex]17x[/tex].

Step-by-step explanation:

Now we need to find about what is the rate of change of the cost in dollars with respect to the number of miles.
First we need to rewrite [tex]y=3.75 + 1.5(x-1)[/tex] in y=mx+b form
[tex]y=3.75 + 1.5(x-1)[/tex]
[tex]y=3.75 + 1.5x-1.5[/tex]
[tex]y=2.25 + 1.5x[/tex]
[tex]y=1.5x + 2.25[/tex]
comparing with y=mx+b, we get m=1.5
Hence rate of change of the cost in dollars with respect to the number of miles is 1.5.

How to find the area of the path?The yard is rectangular in shape.In the figure, there are two right angles triangles on two sides of the pathArea of the path = (Area of the rectangular yard) - (Area of two right angled triangles)The width of the path is 3 feet. So, the base of the right angled triangle = (12-3) feet = 9 feet Area of the right angled triangle = base x height/2

A jacket is on sale for 70% of the original price. If the discount saves $45, what was the original price of the jacket? What is the sale price?
Answers
First you divide 45/7 to find out what 10% of 45 is since 70% is $45
45/7= 6.42, so now you multiply 6.42 by 3 to fin out what the 30% is
6.42(3)= $19.28
Now you add $19.28+45 to add the 30% and the 70%, which is $64.28
100 - 70% = 30
0.30 × p (p=45)
0.30 × 45 = 13.5

Which statement about these rectangles is true ?
Answers
the answer for this question is the dilation is reduction
The statement which is true about these rectangles is:
The dilation is an enlargement.
Step-by-step explanation:Dilation Transformation--
It is the translation which changes the size of the original figure.The shape of the figure is conserved.Also, in dilation either the size increases (i.e. the figure enlarges) or it decreases( i.e. the figure reduces).Also, in a polygon if there is a dilation then there is a scalar multiplication in each of the sides of the polygon.If the scalar multiple is greater than 1 then there is a enlargement.and if the scalar multiple is less than 1 but greater than 0 then there is a reduction.Here we see that each of the sides of the original figure is multiplied by "1.5" to obtain a larger rectangle.
This means that the dilation is a enlargement.
( since the scalar is strictly greater than one )
