can i have some help?

Answer:

y = 7

z = 1

Step-by-step explanation:

If the triangles are congruent

AB = QR

y+ 34 = 41

Subtract 34 from each side

y = 41-34

y = 7

and QP = BC

38 = z+37

Subtract 37 from each side

38-37 = z

1 =z

Answer:

y = 7

z = 1

Step-by-step explanation:

The triangles are congruent, the length of the sides are equal.

y + 34 = 41

y = 41 - 34

y = 7

z + 37 = 38

z = 38 - 37

z = 1

Answer:

D.

Step-by-step explanation:

Since this isn't a credit card, there are no interests or fees on a debit card, so A is incorrect. B is also incorrect. You only need identification when you are withdrawing or depositing at a bank, but purchases made in stores or online do not need your identification. You also don't need to record transactions in your checkbook (but it is recommend to keep track of purchases). Modern day technology already records transaction history and all you need to do is access it online.

D is correct because if someone steals your PIN for your debit card, they could go to stores and use that money. You can dispute charges and report to the bank if that happens.

Answer:

Monique made an error when writing the factored expression.

Step-by-step explanation:

The factorisation of the expression 4x+16xy is 4x(1+4y).

The given expression is 4x+16xy.

In mathematics, factorization or factoring consists of writing a number or another mathematical object as a product of several factors, usually smaller or simpler objects of the same kind.

Now, 4x=2×2×x and 16xy=2×2×2×2×x×y

so, the GCF of terms 4x.

Now, 4x(4x/4x+16xy/4x)=4x(1+4y)

Therefore, the factorisation of the expression 4x+16xy is 4x(1+4y).

Answer:

(A) 1

Step-by-step explanation:

We know that the formula is x = (m/m+n) (x2-x1) + x1.

But the trick to the question which is why everyone is getting it wrong is because it asks for F to D not D to F.

The reason everyone else was getting 4 was because they were using this.

They solved the equation x = (8/8+5) (9-[-4]) -4 where it was D to F. This equation does turn out to be 4 but it is incorrect.

However, the correct equation (because it is supposed to be F to D) is

x = (8/8+5) (-4 -9) +9 which is in fact equal to 1.

Answer:

All negative numbers

Step-by-step explanation:

They are not whole numbers

Answer:

0

Step-by-step explanation:

Since negative numbers are not considered whole numbers, they are not included here. All natural numbers are whole numbers but not all whole numbers are natural numbers. 0 is a whole number but it doesn't count as a natural number which makes the answer 0

Answer:

B

Step-by-step explanation:

X is the domain.

The function comes from -∞ and goes to ∞

So B is the answer.

Answer:

C. 46 degrees

Step-by-step explanation:

In a rotation all angles and side lengths are preserved so the angle measure will be the same in both the image and pre-image.

Answer:

C. 46°

Step-by-step explanation:

When you rotate a shape, it's angles and size do not change. The only things that change are its orientation and location.

Answer:

A) if and only if a = 0

Step-by-step explanation:

Since Z1 = 12 + 6݅  and Z2 = a + bi , then the product, Z1Z2 = (12 + 6)(a + bi)

Z1Z2 = (12 + 6)(a + bi)

Expanding the brackets, we have

Z1Z2 = 12a + 12bi + 6a + 6bi

Collecting like terms, we have

Z1Z2 = 12a + 6a + 12bi +6bi

Z1Z2 = 12a + 6a + (12b +6b)i

Simplifying, we have

Z1Z2 = 18a + 18bi

For Z1Z2 to be imaginary, then the real part must be zero.

That is 18a = 0 ⇒ a = 0

So, Z1Z2 is imaginary if and only if a = 0

Answer:

c = 6√2 cm

Step-by-step explanation:

a² + b² = c²

6² + 6² = c²

36 + 36 = c²

108 = c²

c = ± √108 = ± 6√2

Since the side length of a triangle can't be negative, c = -6√2 is an extraneous solution; therefore the answer is c = 6√2.

Answer:

72 cm or 6 square root of 2

Step-by-step explanation:

a^2+b^2=c^2

6^2+6^2=c^2

36+36=72

c= 72 cm.  or 6 square root of 2

Answer:

Choice A: -36 + (-8)

Step-by-step explanation:

We want to find the equivalent expression to -36 - 8

The correct option is Choice A.

Choice A is -36 + (-8)

The reason is that the product of the signs + and - is -, i.e.

+ * - = -

Hence, + (-8) is the same thing as -8 and Choice A becomes -36 - 8

Answer:

The answer is

Step-by-step explanation:

To find side b we use cosine

cos ∅ = adjacent / hypotenuse

From the question

side c is the hypotenuse

side c = 48 feet

side b is the adjacent

∅ = 35°

We have

cos 35 = b/c

cos 35 = b / 48

b = 48 cos 35

b = 39.319

b = 39.32 feet to 2 decimal places

Hope this helps you

Answer:

b ≈ 39.32 ft

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos35° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{b}{c}[/tex] = [tex]\frac{b}{48}[/tex] ( multiply both sides by 48 )

48 × cos35° = b, thus

b ≈ 39.32 ft ( to 2 dec. places )

Answer:

[tex]g(x) = 8\cdot (x-3)^{2}-5[/tex]

Step-by-step explanation:

Given that parent function represents a parabola, the standard form with a vertex at (h,k) is now described:

[tex]y-k = C\cdot (x-h)^{2}[/tex]

[tex]y = C \cdot (x-h)^{2} + k[/tex]

Where:

[tex]x[/tex], [tex]y[/tex] - Independent and dependent variables, dimensionless.

[tex]h[/tex], [tex]k[/tex] - Horizontal and vertical component of the vertex, dimensionless.

[tex]C[/tex] - Vertex factor, dimensionless. (If C > 0, then vertex is an absolute minimum, but if C < 0, there is an absolute maximum).

After reading the statement of the problem, the following conclusion are found:

1) New function must have an absolute minimum: [tex]C > 0[/tex]

2) Transformation to the right: [tex]h > 0[/tex].

3) Transformation downwards: [tex]k < 0[/tex]

Hence, the right choice must be [tex]g(x) = 8\cdot (x-3)^{2}-5[/tex].

Answer:

The Amount amount he pays each month is 298

Step-by-step explanation:

Given:

Total amount of new car (including interest) = 17,880

Payment is splited over 60 months i.e time = 60 months

Required:

How much will be paid each month

To find the amount to be paid each month use the formula:

Monthly payment = Total amount / time

[tex] = \frac{17880}{60} = 298 [/tex]

Therefore, the amount William pays each month is 298

Tinh's reduction is incorrect. He should only divided the side lengths by 3.

Dividing the angle measures by 3 would make it into a completely different triangle.

Dividing only the side lengths will make the triangles slightly alike.

The answer is A.

Period(n)=12 months

Time(t)=10 years

A=p(1+r/n)^nt

=17,542.2

A=$17,542.2

Marcus will receive a total of $17,542.2 when he redeems the certificate of deposit (CD) at the end of 10 years

Answer:

y = 0.5x + 2

Step-by-step explanation:

the y-intercept is 2, as shown in the graph

the slope is 0.5. this is because while the x-value goes up by 2, the y-value goes up by one (from 0, 2 to 2, 3).

using the slope formula of rise / run, you get 1/2, which is equal to 0.5

The Lewis family and the Perry family each used their sprinklers last summer. The water output rate for the Lewis family's sprinkler was 15 L per hour. The water output rate for the Perry family's sprinkler was 40 L per hour. The families used their sprinklers for a combined total of 65 hours, resulting in a total water output of 1850 L . How long was each sprinkler used

Answer:

Hours of use of sprinkler by Lewis family is 30 hours.

Hours of use of sprinkler by Perry family is 35 hours.

Step-by-step explanation:

Let W = hours of use by Lewis family

65 - W = hours of use by Perry family

Then;

15W + 40*(65 - W) = 1850

15W + 2600 - 40W = 1850

(15 - 40)W = 1850 - 2600

-25W = −750

W = 750/25 = 30

Therefore;

W = 30

65 - W = 65 - 30 = 35

Hence,

Hours of use by Lewis family is 30 hours.

Hours of use by Perry family is 35 hours.
