1) Which expression has a base with an exponent of 4?
1. p + 4
2. 4 • I • y
3. 4z^3
4. 3m^4
Answer:
Number 4 has an exponent of 4.
Step-by-step explanation:
The ^ thingy is referring to an exponent. The number after that symbol is the exponent. Therefore, the last answer is the solution to this problem.
The expression which has a base with an exponent of 4 is [tex]3m^4[/tex]
Given two integers a and b, in indices form, we can write;
[tex]a^b[/tex] where:
a is the base
b is the exponent
From the given question, we are to find the expression has a base with an exponent of 4. From the given option;
In p + 4, 4 is not an exponent falsifying option AFor option 2, 4ly, 4 is not an exponent but a baseFor the expression, [tex]4z^3[/tex] 4 is the base, and 3 is the exponent falsifying option C.For the expression, [tex]3m^4[/tex] 3 is the base while 4 is an exponent. Hence the option D is correct.Hence the expression which has a base with an exponent of 4 is
[tex]3m^4[/tex]

Step-by-step explanation:
Congruent triangles are exact same triangles, but they might be placed at different positions. The statement is true.
What are congruent triangles?Suppose it is given that two triangles ΔABC ≅ ΔDEF
Then that means ΔABC and ΔDEF are congruent. Congruent triangles are exact same triangles, but they might be placed at different positions.
The order in which the congruency is written matters.
For ΔABC ≅ ΔDEF, we have all of their corresponding elements like angle and sides congruent.
Thus, we get:
[tex]\rm m\angle A = m\angle D \: or \: \: \angle A \cong \angle D \angle B = \angle E\\\\\rm m\angle B = m\angle E \: or \: \: \angle B \cong \angle E \\\\\rm m\angle C = m\angle F \: or \: \: \angle C \cong \angle F \\\\\rm |AB| = |DE| \: \: or \: \: AB \cong DE\\\\\rm |AC| = |DF| \: \: or \: \: AC \cong DF\\\\\rm |BC| = |EF| \: \: or \: \: BC \cong EF[/tex]
(|AB| denotes the length of line segment AB, and so on for others).
In the two triangles, ΔACD and ΔBCD,
DC is the common side
∠ADC = ∠BDC = 90°
∠ACD = ∠BCD (Given)
Thus, the two triangles are congruent and the sides AD≅DB.
Hence, the statement is true.

Answer:
144.6°
Step-by-step explanation:
180-35.4
144.6°
Answer:
144.6
Step-by-step explanation:
Supplementary angles add to 180
Let x be the unknown angle
x + 35.4 = 180
Subtract 35.4 from each side
x = 180-35.4
x =144.6

From 1995 - 2008 in the US 648 people were struck by lightening. 531 of them were men. You want to see if this observation differs from the null hypothesis, that 50% of people who are hit by lightening would be men, based on the proportion of men in the population as a whole. Calculate the probability under the normal distribution of getting a result of 531 or more (including the continuity correction). Use the binomial test with a normal approximation. What is your conclusion?
Answer:
Because z is higher than any given value in the chart we come to the conclusion To reject null hypothesis
Step-by-step explanation:
Sample proportion = p= 531/648 = 0.8194
This is the proportion of men that were hit by lightening
Null hypothesis: H0: p = 0.5
Alternate hypothesis: H1: p ≠ 0.5
Test statistics z = 0.8194-0.5/(√0.5x0.5/648)
= 0.8194-0.5/√0.0003858
= 0.3194/0.019642
= 16.26
Since the z > 1.96 (at 5% significance) we reject the null hypothesis.
Therefore in conclusion we say z is higher than given values in the chart so we reject null hypothesis.

Determine if the ratio or rates are equivalent: 120 calories in 2 servings; 360 calories in 6 servings OMG PLS HELP ASAP I NEED HELP YOU GET 25 PIONTS
Answer:
No, they are not equivalent
Step-by-step explanation:
Because
120/2 Can not be divided equally into 360/6
Answer:
Yes
Step-by-step explanation:
They are equivalent because if you write the ratio's out, you get 120:2 and 360:6. If you then simplify both, you get 60:1. To simplify these, you need to find a common factor. In 120:2, you can tell that both numbers can be divided by two because they are both even. After dividing, you get 60:1. In 360:6, you can tell that both numbers can be divided by 6 since they both are multiples of 6. After dividing, you get 60:1. Because these to ratio's are equal, they are equivalent.
A banquet hall has just two sizes of tables.
One size seats exactly 5 people, and the other size seats exactly 8 people.
At tonight’s banquet, exactly 79 people will be seated at less than one dozen tables, and there will be no empty places.
How many tables of each size will there be at the banquet?
Answer:
3 8 person tables. 11 5 person tables.
Step-by-step explanation:
Given the functions:
f(x) = x2 - 9, and g(x) = x3 + 4x² + 8x – 7, find h(x) = f(x) + g(x).
h(x) = - x3 +5x2 + 8x - 16
h(x) = x3 + 3x² + 8x + 2
h(x) = x3 + 5x² + 8x – 16
h(x) = -x3 - 3x2 – 8x - 2
h(x) = -x3 + 3x2+8x+2
Answer: h(x)=x³+5x²+8x-16
Step-by-step explanation:
In this problem, we are given f(x) and g(x). The problem asks to find h(x)=f(x)+g(x). Since we are given f(x) and g(x), we can directly add them together.
h(x)=x²-9+x³+4x²+8x-7 [combine like terms]
h(x)=x³+5x²+8x-16
Now, we know that h(x)=x³+5x²+8x-16 after we have combined like terms.

A 2 3/4 inch candle burns down in 11 hours. At what rate does the candle burn, in inches per hour?
Answer:
1/4 or or 0.25
1Step-by-step explanation:
just do 2.75 divided by 11 and you get your answer
At rate 0.25 inch per hour the candle burn.
What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
A 2 3/4 inch candle burns down in 11 hours.
Now,
Since, A 2 3/4 inch candle burns down in 11 hours.
Hence, The rate in which the candle burn, in inches per hour is;
= [tex]2 \frac{3}{4}[/tex] ÷ [tex]11[/tex]
= 11/4 ÷ 11
= 11/4 x 1/11
= 1/4 inches per hour.
Thus, At rate 0.25 inch per hour the candle burn.

Answer:
its adding 3
Step-by-step explanation:
So if you had 6 cupcake two days ago, than yesterday there was 9, so tomorrow you should have 12 cupcake and so on
The requried pattern of cupcakes is given by adding 3 cupcakes each day and the pattern comes out as 6, 9, 12, 15, 18, 21, and so on for the subsequent day.
What is a sequence?The sequence is a pattern of placing the values in a specified manner.
Here,
Assuming that the pattern is to add 3 cupcakes each day, the continuation of the pattern would be:
Two days ago: 6 cupcakes
Yesterday: 9 cupcakes
Today: 12 cupcakes
Tomorrow: 15 cupcakes
Day after tomorrow: 18 cupcakes
In five days: 21 cupcakes

Step-by-step explanation:
A six sided polygon should have a total degree total of 720 degrees. 105+142+140+124+88+x=720. When you find x, it should equal 121 degrees. Since x and y are both on a straight line, that line has to be 180 degrees. These are supplementary angles. 180-121 should equal 59.

D. Dilation and reflection
Step-by-step explanation:
There are 4 main types of transformations, rotation, reflection, translation, and dilation. 3 of these transformations are defined as rigid, rigid means that the transformation preserves angles and distance between points. If these aspects are preserved than the image is congruent. The only non-rigid transformation listed is dilation, therefore D must be correct.
