Answer:
Isosceles triangle
Step-by-step explanation:
Given
Triangle ABC
Required
Reflect across BC and name the triangle according to length of its side
When the triangle is reflected across line BC, the new triangle is ACA (see new attachment)
And the sides of this ACA are:
AC, CA and AA
Such that
AC = CA
and
[tex]AA = 2 * AB[/tex]
[tex]AA = 2AB[/tex]
From the description above, we have two sides (AC and CA) of the triangle to be equal.
By classification of sides, when two sides of a triangle are equal; such triangle is an isosceles triangle
Triangle ACA' has two equal sides, based on the side lengths, triangle ACA' can be classified as: an isosceles triangle.
Recall:
An isosceles triangle has two equal side lengths which lie opposite each other.Given that triangle ABC is a right triangle, if we reflect it across line BC, we will have mirror figure of right triangle ABC, forming triangle ACA'.
That is, two right triangles of ABC, which are reflections of each other, will form triangle ACA'. (See image attached).
Thus, this means that:
A'B = AB (congruent sides)Therefore,
A'A = 2(AB) or 2(A'B)Also, CA = C'A (congruent sides)
This means that, triangle ACA' has two equal sides that are opposite to each other.
Therefore, based on the side lengths, triangle ACA' can be classified as: an isosceles triangle.

3(2x-4)+6=30
x=___
Answer:
x = 6
Step-by-step explanation:
Use distributive property: a(b + c) = a*b + a*c
3(2x - 4) + 6= 30
3*2x - 3*4 + 6 = 30
6x - 12 + 6 = 30
6x - 6 = 30
6x = 30+ 6
6x = 36
x = 36/6
x = 6
Answer:
x = 6
Step-by-step explanation:
Simplify 3(2x-4) first: 3 (2x) 3(-4) =
6x - 12+6 = 30
Combine like terms: -12 + 6 = -6
6x - 6 = 30
Add 6 to both sides: 6x = 36
Divide both sides by 6: x = 6
CHECK:
3( 2(6) - 4) +6 = 30
3 (12-4) +6 = 30
3(8) +6 = 30
24+ 6 = 30
30 = 30
write an equation for the line in slope intercept form.
Variable on both sides
John will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $57.96 and costs an additional $0.12 per mile driven.
The second plan has an initial fee of $47.96 and costs an additional $0.16 per mile driven. How many miles would John need to drive for the two plans to cost
the same?
II miles
Х
?
So for starts we can go 0.16 x 63 miles = 10.04 so the total for the second plan would be $58 with driving 63 miles. and for the first plan would be 0.12 divided by 3 would be 0.04 so we add them together and we get $58 with driving a 3rd of a mile.
Overall:
1st plan: $58 with driving a 3rd of a mile.
2nd plan: $58 with driving 63 miles.
Angus has $3,000 he want to invest. What interest rate compounded continuously does an account need to offer so that Angus has $5,500 in 8 years?
Answer:
The interest rate is 7.58%
Step-by-step explanation:
Compound continuous interest can be calculated using the formula:
A = P[tex]e^{rt}[/tex], where
A is the future value of the investment, including interestP is the principal investment amount (the initial amount)r is the interest rate in decimalt is the time the money is invested for∵ Angus has $3,000 he want to invest
∴ P = 3000
∵ The interest rate is compounded continuously
∵ Angus has $5,500 in 8 years
∴ A = 5500
∴ t = 8
→ Substitute them in the rule above to find r
∵ 5500 = 3000[tex]e^{8r}[/tex]
→ Divide both sides by 3000
∴ [tex]\frac{11}{6}[/tex] = [tex]e^{8r}[/tex]
→ Insert ㏑ in both sides
∵ ㏑( [tex]\frac{11}{6}[/tex] ) = ㏑([tex]e^{8r}[/tex])
→ Remember ㏑([tex]e^{n}[/tex]) = n
∴ ㏑( [tex]\frac{11}{6}[/tex] ) = 8r
→ Divide both sides by 8
∴ 0.07576697545 = r
→ Multiply it by 100% to change it to a percentage
∴ r = 0.07576697545 × 100%
∴ r = 7.576697545 %
→ Round it to the nearest hundredth
∴ r ≅ 7.58
∴ The interest rate is 7.58%

1. A = H

(b) Ingrid’s claim is correct, but her steps are incorrect
Step-by-step explanation:
As nearly as we can tell from the problem statement, Ingrid's table looks like the one attache. We have highlighted the incorrect steps.
Step 3 should read ...
0·cos(y) -(-1)·sin(y) = sin(y) . . . . . . . . . sin(-π/2) = -1
Step 4 should read ...
0 + sin(y) = sin(y)

PLEASEEE I NEED HELP
i'm going to assume you're supposed to solve for x
Answer:
x = -2
Step-by-step explanation:
so you're trying to get x out of the equation and by it self
i would start this off by setting the equation equal to 0
then subtract 6
i would then divide by 3 on each side
you should then have x+4=2
you then subtract 4 to cancel it out
you then get your answer of x = -2

Jake wanted to measure the width of the pond, so
he drew this diagram of two similar triangles.
What is the approximate width, w, of the pond?
Answer:
C
Step-by-step explanation:
Applying the similar triangle theorem, the width, w, of the pond is approximately: D. 13 feet
Recall:
Similar triangles will have corresponding sides that have proportionate length based on the similar triangle theorem.
The two triangles in the diagram are similar.
Therefore, the ratio of their corresponding sides will be equal (i.e. corresponding side lengths that are proportional).
Thus:
[tex]\frac{5}{w} = \frac{7}{18}[/tex]
Divide both sides by 5[tex]w = \frac{18 \times 5}{7} \\\\w = 12.9[/tex]
Therefore, applying the similar triangle theorem, the width, w, of the pond is approximately: D. 13 feet

4) y = -3x - 7
-6x - 2y = 14
Answer:
The system of equations has infinite solutions
Step-by-step explanation:
∵ y = -3x - 7 ⇒ (1)
∵ -6x - 2y = 14 ⇒ (2)
→ Substitute y in equation (2) by equation (1)
∴ -6x - 2(-3x - 7) = 14
→ Simplify the left side
∵ -6x - 2(-3x) - 2(-7) = 14
∴ -6x + 6x + 14 = 14
→ Add the like terms in the left side
∵ (-6x + 6x) + 14 = 14
∴ 0 + 14 = 14
∴ 14 = 14
∵ The variable is disappeared and the two sides of the equation equal
∴ The equation has many solutions
→ That means x and y can be any numbers
∴ The system of equations has infinite solutions
